Description

 Method for guiding motion sequences as well

 Training device for guiding movement sequences

The invention relates to a method for guiding movements of a user in an exercise as well as a training device for guiding movements of a user.

In sports, especially in the fitness field, while dancing or for the treatment of injuries or movement disorders, such as after a stroke, the correct execution of movements is sought. Wrong movements lead to worse performance and in the worst case even injuries.

For example, when training with free weights, ie without such devices that cause the movement, a risk of injury is given when exercises are performed incorrectly. Therefore, an experienced trainer usually looks after a trainee in order to be able to correct the movements of the trainee. This prevents injuries and the rehearsal of incorrect movements.

However, the services of an experienced trainer or therapist to use, on the one hand costly and on the other hand requires scheduling appointments with the trainer. As a remedy exercise devices are known which have a screen and a

Have camera in which the exerciser is detected by the camera and on the screen, the image captured by the camera is displayed in life size. This allows the user to see when the movements are performed on the screen. In addition, an analysis of the movements of the exerciser can be performed by a control unit, so that the user can simultaneously be shown on the display with correction notices, example videos or target areas that are related to the reproduction of his body on the screen. Problematically, however, such systems do not provide a realistic and delay-free image of the exerciser, so that the trainee's possibilities for self-correction are impaired.

It is therefore an object of the invention to provide a method for guiding movements of a user and a training device for guiding movements, with which the user can control himself without restrictions and at the same time the user without the presence of a trainer through the correct sequence of movements of the exercises lead and / or draw attention to incorrect movements.

The object is achieved by a method for guiding movements of a user in an exercise by means of a training device, which comprises a mirror with a reflection surface, at least one display device, at least one sensor, which is directed to the user, and a control unit, the measurement data from receiving at least one sensor and controlling the at least one display device, comprising the steps of: a) detecting the user by the at least one sensor, b) determining the position of the user's eyes in relation to the reflection surface of the mirror, c) determining the position at least one representative body part of the user representing the position of the body of the user with respect to the reflection surface of the mirror, and d) generating at least one target area associated with at least one body part used in the exercise on the reflection surface of the mirror in dependence on the Position of the user's eyes and the position of the representative body part such that the target area is represented at the location on the reflective surface by the display device at which the mirror image of the at least one body part used in the exercise is received by the user's eyes should be located and / or moved according to the progress of the exercise being performed. The target area can be created by visual representations of the display devices that are perceivable by the user. The positions are given in relation to the reflection surface, for example by a suitable common coordinate system, in that both the vertical distance to the reflection surface, the height above the ground and the lateral offset parallel to the reflection surface can be determined.

The determination of the position of the eyes need not be made by direct measurement of the eyes. Rather, the position of other body parts can be measured, from which then closed to the position of the eyes or the position can be estimated. For example, it is sufficient to determine the position of the head in order to be able to carry out a sufficiently accurate determination of the position of the eyes.

The position of the mirror image on the reflection surface could also be directly based on the position of this other body part. In this case, however, an implicit position determination of the eyes takes place, since their position is decisive for the position of the mirror image. The term "determination of the position of the eyes" and other formulations used therefore also encompass this implicit position determination of the eyes in the context of this invention. The same applies to the representative body part.

It is also conceivable that the eyes are the representative part of the body.

The invention is based on the finding that it is possible to guide a user through representations on his mirror image through movement sequences of an exercise. This allows the advantages of a mirror to be used, such as the realistic and instantaneous reproduction of the user.

By determining the position of the user's eyes and the position of a representative body part of the user, it is possible for the control unit to determine the position of the mirror image on the reflection surface of the mirror at which the user actually perceives his mirror image. The determined position of the perceived mirror image on the reflection surface of the mirror is then used to output target areas via the display device so that they are perceived by the user on or next to his own mirror image. By means of these target areas, it is then possible for the user to be guided through a sequence of movements.

In the context of this invention, in part shortened, it is referred to display displayed elements in relation to parts of the body of the user. This always means, even if not explicitly stated, that elements in the specific reference to the mirror image of the user received by the eyes of the user are displayed on the reflection surface by the display device.

A color in which the target area is displayed may be adapted to the position of the target area on the mirror and / or depending on the position of the user's eyes. As a result, a target area can be perceived particularly clearly by a user.

Preferably, the position of the user's eyes is determined continuously or once before or at the beginning of the exercise, and the location where the target area is located is adjusted continuously or once before or at the beginning of the exercise to the position of the eyes. Continuous means permanent or with a repetition rate of 60 Hz or more. This ensures that the target areas are always displayed so that they are received by the user's eyes in the intended location to the user's mirror image.

In particular, the representation of the target area is dynamically adjusted based on a position of the perceived mirror image on the reflecting surface of the mirror. This means that a displayed target area at any time during an exercise is exactly adapted to a current body reflection of the user.

For example, as a user moves toward or away from the mirror during an exercise, a scaling of the target area is continually adjusted. Even if a user moves aside during an exercise, follows the target area of the body reflection of the user. The user can thus perform the exercises in a particularly effective and targeted manner.

According to a further embodiment, at least one visual representation with the mirror image of the user can move on the reflection surface. As a result, a user can always see all the displayed items well, even if the position of the user's body or the position of the user's eyes changes during an exercise. This can be the case when performing squats, for example. When the user goes to his knees, the visual image moves down a corresponding distance. The visual representation can be made so that they are always arranged in the user's perspective, but do not disturb the user.

Examples of visual representations following the user's mirror image are displays such as a speedometer, a balance display, a number of repetitions, a progress bar, a training video, or other cues.

For example, at least a part of the at least one target area is represented by a geometric figure by means of the display device. The geometric figure may be a circle, an ellipse, a square, a rectangle, a star, or another polygon or polygon. Also conceivable are a line or several lines that have to be passed. In this way, a simple representation of the target area is possible.

According to an embodiment, scaling of the target area occurs such that a target area is adjusted to the size of a body or body part of the user. If a mirror is used which, due to its size, can only reflect a part of the user's body, for example only a lower part of the body or only an upper part of the body, the target area is also displayed only for the part of the body being reflected.

In addition, the size of the target area may be adjusted to indicate a desired distance of a body or body part to the mirror, particularly to signal movement toward or away from the mirror. For example, the target area or a portion of the target area may increase to indicate to the user that he or she is a body part should move forward. Likewise, the target area or a portion of the target area may shrink to indicate to the user that he should move a body part backward.

In particular, the control unit recognizes which body part of the user is displayed in the mirror or is perceived by the user. This can be done based on a height, a position of the user's eyes or a position of a body part of the user, for example a position of the user's head.

In one embodiment variant, the at least one part of the at least one target area is at least part of a silhouette of a body, the silhouette being displayed on the reflection surface by the display device in such a way that the silhouette is received by the eyes of the user as if the silhouette were the one same or slightly larger size, proportions, and / or position as the user's mirror image received by the user. The silhouette may represent a human body or the outlines thereof or be the image of a person, for example, a famous athlete. It is also conceivable that the silhouette is the image of an animal, a mythical creature or a fictitious figure, like the image of a superhero. The user thus gets the impression that his mirror image is inside the silhouette. The silhouette can be an indication of the total perceived by the user in the mirror body.

The silhouette can be generated by measuring the user's body, or there is a stored silhouette that matches the user's mirror image.

In a further embodiment variant, at least one posture indicator is displayed on the reflection surface by the display device on which the mirror image of the user received by the user's eyes is located. The posture indicator helps the user to control his movement. The user can use the posture indicator to make it easier to tell if he is in the right posture or not. The size of the attitude indicator can be continuously adjusted to a size of the mirror image of the user. Thus, the user can always perceive the attitude indicator superimposed with its mirror image.

For example, the posture indicator may include a line that illustrates an attitude of the user. For example, the line may represent a connection between the shoulders or the hip bones. When the line is horizontal, the user realizes that his upper body is upright, which is correct in most exercises. If the line is inclined, there is probably a malposition. Alternatively or additionally, the posture indicator may comprise a vertical line representing the user's spine. Based on the slope of the line both in depth and sideways, a user can see if he is in a straight posture or if his body is tilted forward or backward. According to an embodiment, the posture indicator may be a stick figure illustrating a body of the user. The stick figure contains several of the previously described lines. Compared to a single line, a stick figure gives a user even better control over his posture. Alternatively or additionally, the posture indicator may comprise points imaged on joints or relevant body points of the mirror image. For example, to properly perform the exercise, the user has to hold the dots in displayed target areas.

It is also conceivable that the representation of the attitude indicator changes in the course of a training. For example, the posture indicator may change from a stick figure to a single line to one or more points.

According to one embodiment, the target area and the attitude indicator may be displayed simultaneously. The user then has a double control, namely by comparing his mirror image with the target area and by the position of the attitude indicator. However, it is also conceivable that the target area and / or the attitude indicator are hidden depending on the time. For example, if an advanced user is trained or recognized as having understood the motion sequence by the user, the target area may be hidden and only the posture indicator may be displayed. In particular, the target area can transform into the attitude indicator and vice versa.

Alternatively, in an advanced user, both the target area and the attitude indicator may be hidden.

The control unit can recognize from a number of correctly executed repetitions or a degree of agreement with a target movement, whether the user is beginner or advanced and react accordingly, in particular the target area and / or the attitude indicator on or hide.

However, in the background, the control unit can always compare the movement of the user with a target movement even if the target area and / or the posture indicator are hidden. If the control unit detects that the user is not performing an exercise correctly, the target area and / or the posture indicator may reappear.

According to another embodiment, the user may manually adjust whether the target area and / or the attitude indicator should be displayed. The user can also switch off all visualizations, in particular the target area and the attitude indicator.

Another embodiment provides that the user is confirmed a correct sequence of movements. For this purpose, a position and / or a trajectory of the joints can be detected and compared with a desired position or a desired trajectory. In this case, the joints of the user can be illustrated during training by the attitude indicator, in particular by points.

If the position and / or trajectory of the joints is correct, appropriate feedback may be given to the user. The feedback can be visual and / or audible. For example, the joints may be green Points are displayed when a correct posture is present or when a correct movement has been performed.

However, if the position and / or trajectory of the joints is incorrect, visual and / or audible feedback may also be provided to the user, for example by representing the joints with red dots.

To assist the user during exercise, a range indicator may be displayed, with areas marked where the joints or body parts should ideally be, or in which the joints or body parts are to be moved (range-of-motion). For example, a desired range of motion and / or an actual range of motion can be displayed. So a user can compare his actual movement particularly well with a target movement.

In order to guide the user through the exercises at the correct speed, the control unit may have access to a controlled course of the exercise comprising a target movement of the at least one body part used in the exercise, the target area and / or the silhouette executes the target movement sequence of the exercise. The silhouette or the target area make the exercise at the right speed. Access here means that the process is stored in a memory, for example the control unit itself, the sequence can be called up by the control unit from the Internet and / or the control unit receives the desired movement sequence in real time from another training device, which receives from the Users of this other training device is being executed. For example, the control unit has access to a control-stored process of the exercise, which comprises a target movement of at least one used in the exercise body part, wherein at least one target trajectory of the display device is generated such that the desired trajectory of the trajectory of the mirror image of the at least one body part corresponds when the user performs the target movement. In this way, the user can also easily capture complex movement sequences. In one embodiment, the control unit has access to a controlled flow of the exercise comprising a desired movement of the at least one body part used in the exercise, wherein the at least one target area is moved such that the user correctly performs the desired movement of the exercise when the user always keeps the mirror image of the at least one body part within the at least one target area. In this way, a simple and very intuitive guidance of the user is possible.

In order to further assist the user in correctly performing the exercise and to indicate errors, the control unit may have access to a controlled course of the exercise comprising a target movement of the at least one body part used in the exercise, the method additionally comprising comprising the steps of: a) determining the position of the at least one body part of the user used in the exercise with respect to the reflection surface of the mirror, b) optionally determining a movement sequence by the control unit that the user performs with the at least one body part used in the exercise, c) comparing the position of the at least one body part used in the exercise and / or the user movement sequence with the target movement sequence; d) determining the difference between the position of the at least one body part used in the exercise and / or the user movement sequence and the sol l motion sequence, and e) outputting an optical signal based on the detected difference by the at least one display device.

The difference can also be zero if the desired movement has been carried out correctly. As part of the signal, for example, a text box, video and / or animation is provided, which is displayed by the display device. In the video or the animation, the target movement by a Person or an avatar are shown, wherein the at least one body part used in the exercise is at least temporarily marked.

Preferably, the optical signal is at least partially that the target area, the desired trajectory and / or an illustrated user trajectory of the mirror image of the at least one used in the exercise body part of the user on which the difference is based, and / or the shape of the target area changes. In this way, the user can be quickly pointed to errors in the movement he has performed. It is possible that additional motion sequences can be added in addition to the already set target motion sequences. This ensures the greatest possible flexibility during training.

The addition of additional target movements, for example, by a trainer performing an exercise in front of the mirror. Previously, the control unit receives a signal, in particular by a manual input of the trainer, that the following exercise should be included. After completion of the exercise, the recorded movement sequence can be added to a series of already existing exercises, in particular as a further desired movement sequence. It is not mandatory that the coach is in front of the mirror, but basically only one sensor is necessary, which receives the movement of the trainer and sends it to the control unit.

So that the user can be notified of errors even more quickly, a marker can be output as at least part of the optical signal in such a way that the marker is displayed on or in the region on the reflection surface on which the mirror image received by the eyes of the user of at least one body part used in the exercise on which the difference is based. The marker may be an arrow that is received by the user's eyes such that the arrow points to the at least one body part used in the exercise. Preferably, the optical signal is at least partially in that a correction reference is displayed, in particular an arrow is shown, which is shown in the surrounding area of the location on the reflection surface, at the the mirror image of the at least one body part used in the exercise, on which the difference is based, is received by the user's eyes, the arrow being received by the eyes of the user such that the arrow points in a correction direction. With the aid of the correction direction, the user can quickly find his way back to the desired movement sequence. For example, the surrounding area of the silhouette is the area that adjoins and / or completely surrounds the corresponding location.

In order not to unnecessarily distract the user, the target area, the desired trajectory and / or at least part of the silhouette can be displayed as at least part of the optical signal, in particular the part of the silhouette corresponding to the at least one body part used in the exercise is displayed on which the difference is based. Otherwise, the target area, the silhouette and / or the desired trajectory are not represented by the display device. In one embodiment of the invention, several body parts of the user are used in the exercise, and for at least one, in particular each of the body parts used an associated target area is provided. To output a signal, it is conceivable that only the body part used in the exercise is used on which the difference is based. In this way it is possible to guide the user through complex and coordinatively difficult exercises with several simultaneously moving body parts.

According to a further embodiment it can be provided that a video transmission can be displayed on the reflection surface of the mirror, in particular a live transmission. In this way, for example, by a trainer hints or a mirror image of the coach on a mirror in front of a user trains.

Furthermore, the object is achieved by a training device for guiding a user's movements, comprising a mirror having a front side and a rear side, at least one display device provided on the rear side of the mirror, at least one sensor facing a training area in front of the mirror Front is directed, and a control unit, which is connected to the at least one display device and the at least one sensor information technology. The display device is such arranged that a display generated by the display device can be seen by the mirror on the reflection surface of the training area. The control unit is set up to carry out the method according to the invention. Information technology means, for example, that the parts can exchange information through a data line or a device for wireless data transmission.

Further advantages and features of the invention will become apparent from the following description and from the accompanying drawings, to which reference is made. In the drawings: FIGS. 1 a and b show a front and rear view of a training device according to the invention,

FIG. 2 shows a sectional view of the training device according to the invention according to FIGS. 1 a and 1 b along the axis II-II,

Figure 3 schematically shows the training device according to Figures 1 a, 1 b and 2 from the user's perspective during operation, Figures 4a to 4c schematically, the training device of Figure 3 from the user's point of view at different times when performing an exercise, the figures 5a to 5c schematically show the training device according to FIG. 3 from the perspective of the user at different points in time when carrying out a further exercise; FIGS. 5d to 5f similar to FIGS. 5a to 5c show the training device according to FIG. 3 from the point of view of the user at different points in time during the execution In another exercise, Figures 6a to 6c schematically show a second embodiment of the exercise device from the user's point of view at various times when performing an exercise, Figures 7a to 7c schematically shows a third embodiment of the exercise device from the perspective of the user at different times in the D perform an exercise, and Figures 8a to 8c schematically show a fourth embodiment of the exercise device as seen by the user at various times when performing an exercise.

FIGS. 1 a, 1 b and 2 show a training apparatus 10 with a base body 12, a mirror 14, a plurality of sensors 16, a plurality of dispensers 18 (FIG. 1 b) and a control unit 20 (FIG. 1 b) in front of a wall W shown.

The training device 10 is suitable for the evaluation and correction of movements of a user B (FIG. 2). Although the illustrated embodiment shows the application for correcting movement sequences in the fitness area, other applications in sports, dance or medical applications in rhea, orthopedics or physiotherapy are possible.

On the base body 12, which may for example be a steel frame and which is only indicated in the figures, the mirror 14 is attached.

The mirror 14 is in the embodiment shown a conventional or safety mirror made of glass or acrylic glass, which has been provided with a reflective coating. For example, an aluminum coating was vapor-deposited or pressed onto the glass or the acrylic glass. However, it is also conceivable that the mirror 14 is only a reflective film, which is fixed to the base body 12 or on the frame or which is spanned by the base body 12.

The mirror 14 has two opposite sides, the side on which the user B performs his exercises is referred to as front V and the area in front of the front V as training area T, and the opposite side represents the rear side R or the technique side. The user B sees the training device 10 so as shown in Figure 1 a.

In addition, the mirror 14 has a reflection surface 21, is reflected to light that comes from the training area T. On the reflection surface 21, the user B sees his mirror image 40. The reflection surface 21 has different regions with different degrees of transmittance, namely a plurality of functional regions 22 and at least one mirror region 24.

Of course, it is also conceivable that the mirror 14 has a uniform transmittance.

In Figure 1 a, the plurality of functional areas 22 of the mirror 14 are shown in dashed lines. The functional areas 22 have a higher transmission compared to the remaining mirror 14, which forms the mirror area 24.

The transmission of the functional ranges is between 5% and 20%, in particular between 8% and 12%.

In contrast, the transmission of the mirror areas 24 is smaller than that of the functional areas 22 and should be as small as possible.

In the embodiment shown, five functional areas 22 are provided, wherein two rectangular functional areas 22 are located on the left edge of the mirror 14 one above the other. Another rectangular functional area 22 with a larger area is located centrally in the mirror 14. This large central functional area 22 may, for example, extend as far as the lower edge of the mirror 14. In particular, both the mirror 14 and the central functional area 22 extend to the ground or almost to the ground. On the side next to the large central functional area 22, two round functional areas 22 with a small diameter of, for example, a maximum of 5 cm are provided substantially at half the height.

Around the mirror 14, the base body 12 is visible, on which four sensors 16 of a first group Si of sensors are arranged. In the exemplary embodiment shown, there is a sensor 16 below, a further sensor 16 above, a third sensor 16 on the left side and a fourth sensor 16 on the right side of the mirror 14.

As can be seen in FIG. 2, the sensors 16 of the first group Si are located in the direction Rs perpendicular to the mirror 14 in the region of the mirror 14. The sensors 16 may be cameras, time-of-flight cameras (ToF cameras), radar sensors, infrared sensors and / or ultrasound sensors.

In the exemplary embodiment shown, the sensors 16 of the first group Si are all cameras or time-of-flight cameras which can record spatial images (3D images) by means of a light transit time measurement.

These ToF cameras usually operate with infrared light and are therefore not located on the back side R of the mirror 14 because the mirror 14 absorbs infrared light.

In addition, an identification device 26 is arranged on the base body 12. The identification device 26 may be a bar code scanner, an RFID reader, a fingerprint scanner, an iris scanner and / or a face scanner.

On the back R of the mirror 14 shown in Figure 1 b, the remaining components of the training device 10 are arranged. Two further sensors 16 of a second group S2 of sensors are mounted on the rear side R of the mirror 14 directly on the mirror 14.

These sensors 16 are provided in the two round functional areas 22 of the mirror 14, so that they can receive light or other electromagnetic radiation from the front side V or the training area T due to the high transmission of the functional areas 22.

For example, the sensors 16 of the second group S2 are radar sensors. However, they can also be sensors of the aforementioned types.

It is conceivable that individual or all sensors 16 are individually adjustable. This allows their angle or position to be adjusted to align the sensors 16, i. to adjust their exhibition area. In particular, the sensors 16 can be adjusted in the vertical direction Rv and / or the horizontal direction RH with respect to the mirror 14.

In Figure 2, the measuring ranges of some sensors 16 are indicated by different lines. However, all measuring ranges extend to the front side V of the mirror 14 in the training area T, so that the sensors 16 on the Front V and the training area T or on the user B on the front V are directed.

In the other three functional areas 22 of the mirror 14, optical display devices 29, in the exemplary embodiment shown, screens 30 are provided as some of the output devices 18. The screens 30 are provided directly on the mirror 14 and touch the mirror 14, so that no stray light from the rear side R of the mirror 14 can pass through the corresponding functional area 22 to the front side V. As a result, representations are produced directly on the reflection surface 21 by the display device 29, in this case by the screen 30. These are due to the small distance between the display device 29 and screen 30 by the user B perceived as they are on the reflective surface 21 itself. Therefore, in the context of this invention for simplicity it is spoken that the display device 29 generates representations on the reflective surface 21, although in reality there is a gap.

Thus, the screens 30 are from the front side V of the mirror 14, i. well readable from the training area T.

The optical display devices 29 may be conventional flat screens (LCD, plasma, OLED, e-ink). However, it is also conceivable that the screens are LCD, LED, plasma, E-ink or OLED foils, which are attached to the mirror 14 or the base body 12.

It is also conceivable that the display device 29 is a projector (beamer).

Two further output devices 18 in the form of speakers 32, d. H. Acoustic output devices 18 are also provided on the rear side R.

In the embodiment shown, all dispensing devices 18 are attached to the base 12. However, it is also conceivable that the output devices 18, in particular the loudspeakers 32, are fastened only to the mirror 14. The control unit 20 is likewise arranged on the rear side R and can be held by the base body 12. The control unit 20 is connected to all sensors 16, the output devices 18 and the identification device 26 in terms of information technology.

In the embodiment shown, this is achieved by cables. However, it is also conceivable that the control unit 20 is connected by means of wireless connections, e.g. Bluetooth or WLAN with the output devices 18, the sensors 16 and / or the identification device 26 communicates.

To assist the user B, the control unit 20 receives data from the sensors 16 and drives the output device 18 based on this data.

It is also possible for the control unit 20 to communicate with sensors (not shown) outside the training device, in particular wirelessly. Such sensors may be, for example, motion and / or acceleration sensors in the sports equipment used or worn by the user during exercise.

When a user B wants to use the exercise device 10, the user B enters the front side V of the exercise device 10 in the exercise area T.

First, the user B identifies himself to the identification device 26, for example by scanning his membership card of the corresponding gym or the corresponding device. For this purpose, the membership card can have a corresponding RFID chip or a barcode that can be read by the identification device 26.

It is also conceivable that the user B can scan his fingerprint, his iris or his face from the identification device in order to identify himself by means of biometric features.

However, it is also conceivable that the face is detected by means of the sensors 16 and evaluated by the control unit 20, so that an additional identification device 26 is not required. After identification, the control unit 20 may retrieve user data about the user B. This user data may be stored in a local memory of the training device 10 or the control unit 20 and / or the control unit 20 may obtain this data from a server in a local network or on the Internet. Also, the control unit 20 may receive user data from the user's smartphone.

The user data includes information about training histories of previous training sessions, their times, and user B's current training schedule. This information, and possibly a greeting, may be output via the output devices 18, in particular via the screens 30, e.g. those located at the left edge of the mirror 14.

The user B then sees his training plan and thus the exercises of the next training that he has to complete. User B can take a closer look at individual exercises, e.g. Example videos let the target movement of the exercise on the screens 30 output, change the exercises or select other functions.

In order to select a function, he can perform predetermined gestures, which are picked up by the sensors 16 and recognized by the control unit 20, so that the exercise device 10 can be operated by means of gesture control. For example, an air bar may be provided, which is a laser-based touch-sensitive sensor that detects touches based on light reflections.

It is also conceivable that the identification device 26 has a touch-sensitive screen with which the training device 10 can be controlled. Instead of a touch-sensitive screen, a touch-sensitive film may be provided, which is arranged in particular on the front side of the mirror. The touch-sensitive film may be embedded between two glass panes of the mirror.

The touch-sensitive screen or the touch-sensitive film can simultaneously be part of the display device 29, so that information can be displayed simultaneously on the touch-sensitive screen or the touch-sensitive film. If user B now wants to start training, he selects the appropriate function or makes the appropriate gesture. The gesture is recognized by the control unit 20 and training begins.

The user B is detected at the latest now, but preferably immediately after the identification, by the sensors 16 of both the first group Si and the second group S2. These data are forwarded to the control unit 20.

The control unit 20 determines from the data of the sensors 16 the position of the body of the user B as well as the position and flexion of the body parts and / or joints of the user B.

The determination is carried out, for example, on the basis of the distance measured by the radar sensors in conjunction with the image data obtained by means of the cameras or the ToF cameras.

In addition, the control unit 20 may also determine the position of the user B's skeleton. The position of the user's B skeleton can also be idealized or approximated.

In addition, the control unit 20 can recognize, based on the data of the sensors 16 by means of image recognition, whether and which devices 36 the user B uses. Alternatively, the control unit 20 can recognize a signature such as a 1D or 2D barcode on the devices 36 for identifying the devices 36.

In the embodiment shown, the user B uses as devices 36 two dumbbells in the hands.

Based on the detected devices 36, the control unit 20 can now close to the exercise that the user B performs or would like to perform. However, it is also conceivable that the control unit 20, based on the training plan of the user B or a selection of the user B, knows which exercise the user B is performing or would like to carry out.

The control unit 20 then accesses a controlled flow of the exercise which contains the body parts 38 of the user B used in the exercise and predetermined target movements which indicate how the movements of the body part 38 used in the exercise are performed correctly.

These predetermined sequences or desired movements are preferably stored in a generally valid, person-independent format, for example, as a time course of the relative movements of the joints to each other or in relation to a body axis and their diffraction.

The control unit 20 can retrieve these sequences or desired movement sequences from a local memory of the training device 10 or the control unit 20 or load it from a server in the local network or on the Internet. It is also conceivable for the control unit 20 to receive real-time sequences of movements from other training devices (not shown) currently being executed by the user of this other training device. The user movement sequences of the user of the other training device are then the sequences or target movement sequences of the user of the training device 10.

The control unit 20 can also be taught new sequences or desired sequences of motion, or the control unit 20 can itself determine or calculate new sequences or desired sequences of motion, which are then stored by the control unit locally or on a server in the local network or on the Internet.

For example, a trainer may activate a learning mode of the exerciser and then perform a new exercise. The execution is detected by the training device and generated from the recorded data, a target movement for this new exercise and deposited. The control unit 20 thus knows, due to the process or target sequence of motion, just like an experienced trainer, how the movement performed by the user B should ideally look like.

In the embodiment shown, the user would like to perform a "side lift" exercise The body parts 38 used in this exercise are the hands of user B. For convenience, those in the exercise Body parts used in the following also called only "used body parts 38".

In detail, the position of the eyes A of the user B relative to the reflection surface 21 of the mirror 14 is determined. This can be done by determining the point of the eyes A in a three-dimensional coordinate system whose zero point is, for example, on the reflection surface 21 and from which the distance to the eye A in the three directions Rs, Rv and RH is determined. For example, the distance Ds in the vertical direction Rs between the eyes A and the reflection surface 21, the height DH of the eyes A above the ground, and the position of the eyes A in the horizontal direction RH, that is, the horizontal offset parallel to the mirror 14, are measured. This can also be done by means of the radar sensors in interaction with the image data of the camera or the ToF camera.

In the same way, the control unit 20 determines the position of a representative body part 39 of the user B.

The representative body part 39 is a body part, e.g. the torso, on the basis of whose position and position on the positions of others, in particular the body parts 38 used can be closed.

The representative body part 39 may be a different body part for different exercises and is preferably a body part that is not or only slightly moved during the performance of the exercise.

For example, the head or torso is in many cases suitable as the representative body part 39, e.g. while doing exercises with the arms standing up.

By means of the position of the eyes A and the position of the representative body part 39, the control unit 20 determines the position of the mirror image 40 of the user B on the reflection surface 21, ie the locations of the reflection surface 21 at which the mirror image 40 received from the eyes A of the user B located. For simplicity, only the "position of the mirror image 40 will be discussed below, although the position depends in particular on the position of the eyes A." The control unit 20 thus transfers the three-dimensional image of the user B, which was detected by the sensors 16, to the two-dimensional reflection surface 21 of the mirror 14.

The control unit 20 can generate representations, such as a target area 42, on the reflection surface 21 by means of one of the display devices 29, which the user B perceives together with his mirror image 40. Based on the knowledge of the location of the mirror image 40, the control unit 20 may determine the location 44 of the representations relative to the location of the mirror image 40 such that the representation and mirror image 40 are from the eyes A of the user B at the desired distance and desired relative position be received.

The color in which the target area 42 is displayed may be adjusted depending on the position of the target area 42 on the mirror 14 and / or depending on the position of the eyes A of the user B. The colors in which advertisements, notes, postural displays or other visual presentation are superimposed can also be adapted according to the position of the eyes A of the user B.

If a representation, for example a circle, in the perception of the user B include his hand, then the location 44 is the location on the reflection surface 21 at which the user B sees the mirror image 40 of his hand. This situation is shown in FIG.

In FIG. 3 and the following figures, in each case only the reflection surface 21 of the mirror 14 is represented as the user B perceives it. By dash-dotted lines, the individual display devices 29 are indicated and the mirror image 40 of the user B and the devices 36 is shown in dashed lines. Only the representations (and the edge of the mirror 14) that are generated by the display devices 29, here by means of the central screen 30, are drawn with solid lines.

The display devices 29 thus do not reproduce an image of the user B, but only the representations that are perceived by the user B together with his mirror image 40. For example, the control unit 20 uses the previously determined position of the eyes A of the user B and the position of the hands of the user B to determine the location 44, and determines the light from the user's hand, for example, by determining the beam path (shown in phantom in Figure 2) B to the eyes A of the user B, the point 44 on the reflection surface 21, at which the received from the eyes A of the user B mirror image 40 of the hand is. This is the point 44 where the user B perceives his hand in the mirror 14.

The control unit 20 then instructs the display device 29 to output display at location 44.

In Figure 3, a circle is displayed by the display device 29 in relation to the position of the mirror image 40 so that the user B gets the impression that the circle includes the mirror image 40 of his left hand. In addition, the name of the user B can be generated on the reflection surface 21 of the mirror 14.

It should be noted that the position of the location 44 depends on both the position of the hand and the position of the eyes A, so that only the user B perceives the circle superimposed on the mirror image 40 of his hand.

An observer standing laterally beside the user B would only see the circle which was apparently randomly generated on the reflection surface 21 without reference to a mirror image 40. This is a great difference from the known devices of the prior art, in which each observer, regardless of his position, would perceive a mark or target area on the corresponding body part. By means of the illustrations, the user B can be guided by the control unit 20 and the display device 29 through an exercise.

In FIGS. 4a to 4c, by way of example, several positions are illustrated in the execution of a repetition of the selected exercise "side elevation". The target movement of the exercise is that the user B is to move his two hands, which thus represent the body parts used in the exercise 38, side of the body with stretched arms upwards.

In order to guide the user B, the display device 29 generates two target areas 42 on the reflection surface 21, which are each assigned to one of the body parts 38 used for one hand.

The target areas 42 are circles in the embodiment shown. However, other geometric shapes such as ellipses, squares, rectangles, stars or other polygons and polygons are also conceivable. The target areas 42 are not used to mark the body parts 38 of the

User B, but show the user B the correct target movement.

For this purpose, the target areas 42 are indeed determined depending on the position of the representative body part 39 of the user B and the eyes A of the user B, but regardless of the exact position of the body part 38 used in the exercise, in this case the hands.

The target areas 42 are thus generated at the locations 44 on the reflection surface 21 at which the mirror image 40 of the body parts 38 used would be located if the desired movement sequence were correctly executed. For example, in Figure 4a, the starting position of the exercise is shown. In the starting position of the exercise, the user's hands should be placed next to his hip. Accordingly, the target areas 42 are located at the locations 44 laterally adjacent to the location of the reflective surface 21 where the eyes A of the user B receive the mirror image 40 of the hips. For simplicity, hereinafter, positions where certain parts of the mirror image 40 are received by the eyes A of the user B are referred to as the positions where the user B perceives the corresponding part of the mirror image 40. However, it should be emphasized that the positions are independent of the cognitive perception of the user B and, in particular, is dependent on the position of the eyes A of the user B. In the case shown in Figure 4a, the mirror images 40 of the hands perceived by the user B are within the target areas 42, so that he has assumed the correct starting position.

In addition to the target areas 42, target trajectories 46 are additionally generated by the display device 29 on the reflection surface 21, which represent the desired movement sequence. The desired trajectories are also generated depending on the position of the representative body part 39. The representation is made in such a way that the user B would see the mirror image 40 of his hands, that is to say the body part 38 used in the exercise, run along the desired trajectory 46 during the correct execution of the desired movement sequence.

Since the representations, that is, in this case, the target areas 42 and the target trajectories 46 depend on the position of the body of the user B, in particular the representative body part 39 and the position of the eyes A of the user B, the position of the eyes becomes A of the user B and also the position of the body of the user B or the representative body part 39 continuously determined by the control unit 20. Continuous means either permanent or with a repetition rate of 60 Hz or more.

However, it is also conceivable that the position of the eyes A of the user B and also the position of the body of the user B or of the representative body part 39 take place once, e.g. when logging on to the training device 10 or once before or at the beginning of each or the first exercise.

Accordingly, the control unit 20 continuously redetermines the locations 44 of the representations, that is, the location 44 of the target areas 42 and also the locations 44 of the desired trajectories 46, and correspondingly outputs them from the display device 29.

By continuously determining the position of the eyes A, a representation of the target areas 42 can also be adapted dynamically. Thus, it can be ensured that the target areas 42 are always displayed in exactly the correct position with respect to a mirror image perceived by the user B. When a user B moves out of his initial position during exercise, for example, sideways or forward toward the mirror or away from the mirror, the representation of the target areas 42 becomes adjusted accordingly. User B can continue training without interruption.

FIG. 4b shows the situation after the starting position shown in FIG. 4a. It can be seen that the target regions 42 have moved along the desired trajectory 46 and the desired trajectory 46 has become correspondingly smaller.

The movement of the target areas 42 takes place in the speed provided for the exercise, which is deposited in the course of the exercise and thus indicate the progress of the exercise. Figuratively speaking, the target areas 42 make the exercise before, so perform the target movement of the exercise.

The user B executes the target movement in the embodiment with his right hand, so that he perceives the mirror image 40 of his right hand within the associated target area 42.

On the other hand, he keeps his left hand in the starting position so that the user B no longer perceives the mirror image 40 of his left hand in the target area 42.

During the execution of the exercise, the control unit 20 also uses the sensors 16 to determine the position of the body part 38 used in the exercise, in this case the hands. Based on the current and past positions of the body part 38 used, the control unit 20 can also determine the movement performed by the user B and thus determine a user movement sequence.

Subsequently, the control unit 20 compares the position of the used body part 38 and / or the user movement sequence with the target movement and determines differences between the position of the used body part 38 and the target movement.

The difference between the position or the user movement sequence and the desired movement sequence can also be zero, that is, the position of the body part of the user B is correct or the user movement sequence corresponds to the desired movement sequence. Here are minor deviations that do not affect the training effect, also seen as a difference from zero.

On the basis of the difference determined, a signal is output to the user B by the output device 18, in particular the display device 29.

In the situation shown in Figure 4b, the difference of the position of the right hand of the user B and the target movement is zero. As an optical signal, therefore, the target area 42 can be colored green. It is also conceivable that the geometric shape of the target area 42 changes as a signal, for example into a star.

On the other hand, the difference of the position and the movement of the left hand of the user is large, so that an optical signal should inform the user B of this difference.

For this purpose, for example, the target area 42 assigned to the left hand can be colored red or flashing. Also, the shape of the target area may change.

In addition, to indicate the current position of the body part 38 used, which causes the difference (here, the left hand), a marker 48 can be output as a part of the optical signal. In the example shown in FIG. 4, the marker 48 comprises an arrow which is placed on the reflection surface 21 such that it points in the perception of the user B to the left hand. The marker 48 also has an exclamation point.

However, other embodiments of a marker 48, such as geometric figures or frames around the used body part 38, which causes the difference, are also conceivable.

In addition, in FIG. 4b, as an indication of correction 50 for the user B, an arrow is displayed which indicates the direction of correction in which the left hand must be moved in order to carry out the desired movement sequence. This arrow is accordingly an arrow facing away from the left hand, which is placed so that the user B perceives it directly next to the mirror image 40 of his left hand. The arrow points in the direction of correction, towards the target area 42. FIG. 4c shows a further, later situation, namely at the time at which the desired movement sequence has ended.

The target areas 42 are now in the places where the user B should perceive the mirror images 40 of his hands if he had performed the target movement correctly. He has done this with his right hand, so that he perceives the mirror image of his right hand within the target area 42, which is assigned to the right hand. This target area 42 may, for example, continue to be colored green.

The user B's hand is now on the outstretched arm at the level of the shoulders next to the user's body. He has by keeping the mirror image 40 of his right hand always within the corresponding target area 42, the target movement is performed correctly and at the right speed.

However, user B still has not moved his left hand, so marker 48 and correction reminder 50 continue to be displayed.

The length of the arrow, which is shown as a correction reference 50, is greater compared to the previous situation shown in Figure 4b, since the difference between the position or the movement of the left hand and the target movement is now greater. For self-checking and as further assistance, the user trajectory 52 performed by the body part 38 used, which is frequently also referred to as range-of-motion, can also be represented. The user trajectory 52 is represented as corresponding to the movement of the mirror image 40 of the user's body portion 38 used in the perception of the user B. In Figure 4c, the user trajectory 52 is shown for the right hand only because the user B has not moved his left hand.

The insertion of the user trajectory 52 can also be displayed and continuously extended during the execution of the movement sequence.

If the desired movement has been carried out correctly, this recognizes the control unit 20 and increases a repeating counter 54 represented by the display device 29 (or reduces the repeating counter 54 in the case of a count-down repetition counter), which informs the user of the number of successful repetitions.

In the example shown in FIG. 4, the repetition counter 54 is output as a number via one of the screens 30, for example via a screen 30 at the edge of the mirror 14.

Also conceivable are, as signals or parts of the signals, text fields which give correction instructions or instructions, or a video or an animation which is output by the display device 29. In the video or the animation, the desired movement sequence can be represented by a person or an avatar. In this animation or the video, the body part 38 used can be marked at least temporarily, for example in order to make clear deviations of the user movement sequence from the desired movement sequence.

In addition, the controller 20 may log the progress of training, the number of iterations, the quality of the user movement procedures, and the like throughout the workout.

If the user B has completed the intended number of correct repetitions for this exercise, the control unit 20 can inform the user B by means of a corresponding output via the dispensers 18 and thus end the exercise.

Also, the control unit 20 may measure and output the time for time-based exercises such as interval training to be performed. User B can then proceed to the next exercise or stop exercising. If the user B terminates the training, the control unit 20 stores the executed exercises together with the number of repetitions and other logged data and adds these to the user data of the user B.

Then, the control unit 20 may update the user data of the user locally or on the corresponding server.

In addition, the control unit 20 can give the user B a summary of the training via the output devices 18.

It is also conceivable that the control unit 20 transmits this summary and / or other of the user data to a smartphone, in particular that of the user.

The user B has thus received a training that corresponds to the training with an experienced coach, but without having to engage another person or to have an appointment with this.

In FIGS. 5a to 5c, the method is shown again with reference to a second exercise, namely squats.

The body parts 38 used in this exercise are the knees as well as the shoulders.

As representative body part 39, feet are used in this exercise because they are not moved. As far as possible, the knees should not be moved in this exercise, so that the target areas 42 are displayed in such a way that the user B always perceives them at the point 44 where the mirror image 40 of his knees was located when executing the correct starting position.

The shoulder area associated with the target area 42 is shown as a horizontal line on the reflection surface 21 at a certain height.

The user B must now, in order to carry out the correct desired movement sequence, lower his shoulders, that is to say one of the body parts 38 used, to such an extent that the mirror image 40 of his shoulders lies below the target area 42 shown as a line. The user B thus goes to the knees in the execution of this exercise, thereby changing the distance between his eyes A from the ground, which also drastically changes the mirror image perceived by him. This movement is indicated in three situations in FIGS. 5a to 5c. By continuously adjusting the locations 44 at which the target areas 42 are displayed to the position of the eyes A of the user B, the target areas 42 for the user will always appear at the same location above the floor. This is particularly important for the target area 42 of the shoulders, which is shown as a line, since the user B should get the impression that the height of the line does not change.

In the perception of the user B and thus in the perspectives shown in FIGS. 5a to 5c, the position of the target areas 42 does not change.

For an observer who does not perform the movement of the user B, the target areas 42 move. Figures 5d to 5f correspond to Figures 5a to 5c, but illustrate another aspect.

The display device 29 can additionally display a visual representation 70, such as a display on the reflection surface 21, which provides the user B with information about his training, for example a speed display, a balance display, a number of repetitions or a progress display, a video of the Trainers, a live video of a user at another training device, a Fehlervisualisierung, a text message or other advice.

The position of the visual representation 70 may also be adapted to a position of the eyes A of the user B and follow the user B as he moves.

In particular, the visual representation 70 is always positioned in such a way that it does not overlap with the mirror image and / or the target area.

Consequently, in the situations illustrated in FIGS. 5d to 5f, when the user B kneels, the visual representation 70 moves by a corresponding one Stretch down when the user gets up again, the visual display 70 moves back up.

As a result, the visual representation 70 is always in a position in which the user can comfortably perceive the visual representation 70, e.g. always at the height of the eyes. FIGS. 6a to 6c and 7a to 7c show further embodiments of the invention which essentially correspond to those of the first embodiment, so that only the differences will be discussed below. Identical and functionally identical parts are provided with the same reference numerals. In the embodiment shown in FIGS. 6a to 6c, an im

Different representation of the target areas 42 used compared to the first embodiment. The exercise performed is again the same as in the first embodiment of Figure 4, namely side elevation.

In this second embodiment, a silhouette 56 is displayed by the display device 29. The silhouette 56 may in the simplest case be the outlines of a human body. However, the silhouette can also be an image of a person, for example, a famous athlete. However, it is also conceivable that the silhouette 56 is the image of an animal, a mythical creature or a fictitious figure, like the image of a superhero. In the initial position, the silhouette 56 is adapted to the contour of the user B's body so that the user perceives the silhouette 56 in accordance with the contour of the mirror image 40 of his body.

The silhouette 56 is thus generated in the same size, proportions and / or position as the mirror image 40 received by the eyes A of the user B.

The target areas 42 are now the parts of the silhouette 56 that represent the body part 38 used in the exercise, in this case the hands.

When performing the exercise, the target areas 42 now move as described for the first embodiment. In this case, this means that the silhouette 56 is moving and thus it appears that the silhouette 56 is executing the desired movement sequence of the exercise. Also in this embodiment, the user B has to hold his mirror image 40 within the target areas 42, he has to almost imitate the silhouette 56 or catch.

In Figs. 6a to 6c, as in the first embodiment, the user B executes the correct target movement only with his right hand and does not move his left hand.

Accordingly, the same markers 48 and correction notices 50 are output as in the first embodiment.

In addition, the part of the silhouette 56 representing the target area 42 of the left hand may be differently colored, for example red and that of the right hand, for example, may be colored green for confirmation.

The repetition counter 54 is represented in this embodiment as a number of circles or the like, with one more circle being filled in for each complete repetition (or being represented as a contour when the counter is counting down).

FIGS. 7a to 7c show a fourth embodiment of the invention. It essentially corresponds to that of the first embodiment, but initially no target area 42 is displayed. This method is suitable for experienced users who only need a little help. The user B thus sees in the initial position, which is shown in Figure 7a, only his mirror image 40 without target areas 42 or other representations.

However, as described with reference to FIGS. 4b and 4c, it does not perform the desired movement sequence with the left hand correctly. Thus, the left hand causes a difference between the position of the at least one body part used in the exercise and / or the user movement process and the target movement.

The target region 42, the corresponding marker 48, the correction indicator 50 and / or the desired trajectory 46 are then generated as a signal. For the used body part 38, which does not cause the difference, so in this case the right hand, neither a target area 42 nor another representation is issued.

It is conceivable, however, that, as can be seen in FIG. 7c, after completion of a repetition for confirmation and as feedback, the user trajectory 52 is briefly displayed even when the desired movement sequence is correctly carried out.

Of course, all types of representation of the target areas 42 or other representations of the various embodiments may be combined as desired. In addition, the situations and exercises described are merely examples of which it is possible to deviate.

It is conceivable, for example, that the control unit 20 can conclude on the exercise performed on the basis of the movements performed by the user B movements. Any combination of the mentioned methods for determining the exercise is conceivable. It is also conceivable that the optical output devices 18 are not screens, but other display means. For example, they may be an LED matrix indicating correct or incorrect repetition only through symbols or the like. The correction suggestions can then be made via another screen or speaker. Also, the training device 10 may be designed differently. It is conceivable, for example, that the base body used is a glass or acrylic glass pane on which a mirror foil with the corresponding areas is applied from the front side. On the back of the screen, the screens can be attached as LCD or OLED films, resulting in a particularly compact design.

It is also possible that by means of the sensors 16 not only the movement of the user B is detected, but also the user B himself and his surroundings. For example, the control unit 20 may then identify and add various objects to the user data, such as user B's clothing. FIGS. 8a to 8c show a further embodiment of the invention.

In the embodiment of the invention illustrated in Figures 8a to 8c, a posture indicator 58 is provided. The attitude indicator 58 is preferably adapted to a body size and / or a size of the mirror image 40 of the user B.

The color representation of the attitude indicator 58 may be adjusted depending on the position of the eyes A of the user B.

In the illustrated embodiment, the posture indicator 58 includes a plurality of points 60 that are imaged on the joints of the user B and lines 62 that illustrate a posture of the user B. If the lines 62 are horizontal, the user B realizes that his posture is correct in the exercise. If a line 62 is inclined, there is a malposition.

The dots 60 may increase or decrease as the user B moves toward the mirror 14 or away from the mirror 14.

Also, the target area 42 may change in size to indicate to a user B that he should move a body part toward the mirror 14 or away from the mirror 14.

Alternatively or additionally, as a posture indicator 58, a vertical line (indicated by broken lines in FIGS. 8a to 8c) may be used to illustrate the user B posture.

The attitude indicator 58 is preferably displayed when the target area 42 is hidden. However, it is also possible to display attitude indicator 58 and target area 42 simultaneously. The posture indicator 58 is displayed superimposed with the mirror image 40 of the user B so that the user B can better control and correct his own movement.

In order to make the training of the user B even more effective, a range display 64 can optionally be displayed as the target area 42. The Range indicator 64 may be displayed as an alternative or in addition to a silhouette 40.

The area display 64 indicates from marked areas 66 where the joints of the user B or the points 60 should be located. For example, an area 66 is provided for each of the points of the attitude indicator 58. For example, these points may be displayed simultaneously with the silhouette described above.

The regions 66 may change in size to indicate to a user B a desired distance of a body part from the mirror 14. For example, if a user B is to extend his hands forward during an exercise, the areas 66 associated with the wrists of user B would increase.

If one or more points 60 are not within the designated areas 66, such as point 60 depicted in FIG. 8b, which is imaged on a left wrist of user B and / or if the size of points 60 is incorrect, then feedback may be provided be given to the user B who indicates to the user B that he must correct his posture.

For example, the dots 60 that are within the designated area 66 and / or the correct size are green, while the dots 60 that are outside the designated area 66 and / or are not the correct size are red.

However, the area display 64 serves less to display a target area to the user B, but rather to correct a posture of the user. The user B is encouraged to hold the dots in the respective target area 42.

In addition, a range of motion 72 may be displayed within which a repetition of the exercise is to be performed. This movement region 72 is shown in FIG. 8c as a hatched area. For example, the wrist of user B should not leave this hatched area, but leave as completely as possible to achieve a repeat. The features of the various embodiments shown may of course be combined. In particular, the different types of target areas 42 may be used simultaneously or sequentially. Thus, it is conceivable, for example, that at the beginning of an exercise, for example when the user B has not yet carried out the corresponding exercise frequently, the silhouette is first used as the target area 42.

If the user has performed some repetitions of the exercises correctly, the type of the target area 42 is changed. For example, the silhouette disappears and subsequently the target areas or attitude indicators of the embodiment of FIG. 8 are used.

For example, based on the degree of coincidence between the movement performed by the user B and the target movement, it can be determined whether the user B performs the exercise correctly. Of course, other target areas 42 or assistance based on the degree of matching may be faded in or out to give the user B exactly the amount of assistance he needs.

For example, the silhouette may be displayed again when the degree of coincidence drops.
