Radar-Based Gesture Recognition for Wearable Electronics
Added Jul 30, 2015 | Rate View top rated
From Google's Advanced Technology And Projects (ATAP), the Project Soli team is developing a new gesture interaction sensor using radar technology. The sensor can track sub-millimeter motions at high speed and accuracy. It fits onto a chip, can be produced at scale, and built into small devices and everyday objects. The interaction sensor runs at 60GHz and can capture motions of a user’s fingers at resolutions and speeds that haven’t been possible before - up to 10,000 frames per second. To get there, the team had to reinterpret traditional radar, which bounces a signal from an object and provides a single return ping. The team built the first prototype, which is a 5x5mm piece of silicon.

I've been in radar design for over 25 years and this is one of the silliest ideas I've ever seen. There is a reason we do image work in the optical region; because it works. And it works FAR better than it ever can in the microwave or MM wave regions. This is a triumph of technology over practicality. Preposterous!

Interesting work! It would be helpful to know the exact resolution range and sampling rate. The expected cost and time of availability. In many applications free form motion does not work well. What are the applications the google team expect to be able to address well?
