WHAT IS PROJECT SOLI?

Project Soli uses invisible radar emanating from a microchip to recognise finger movements.

In particular, it uses broad beam radar to recognise movement, velocity and distance. 

It works using the 60Ghz radar spectrum at up to 10,000 frames per seconds.   

These movements are then translated into commands that mimic touches on a screen. 

The chips, developed with German manufacturer Infineon, are small enough to be embedded into wearables and other devices. 

The biggest challenge was said to be to have been to shrink a shoebox-sized radar - typically used by police in speed traps - into something tiny enough to fit on a microchip.

Inspired by advances in communications being readied for next-generation Wi-Fi called Wi-Gig, leading researcher Ivan Poupyrev's team shrank the components of a radar down to millimetres in just 10 months.
