Google’s Advanced Technology and Projects (ATAP) division announced Project Soli, a radar-based gesture control technology at the I/O developer conference last year. Last year’s development kit was huge to use it in smaller devices such as smartwatches. So Google’s ATAP team with Infineon redesigned the chip to make it 3 times smaller and also reduce power consumption by 22 times, down from 1.2W to 0.054W. The footprint is now also 3x smaller.
