Google’s Project Soli radar is sensitive enough to count sheets of paper and read Lego bricks

Project Soli uses miniature radar to detect gestures.

What does the computer interface of the future look like? One bet from Google is that it will involve invisible interfaces you can tweak and twiddle in mid-air. This is what the company is exploring via Project Soli, an experimental hardware program which uses miniature radar to detect movement, and which recently won approval from the FCC for further study.

Imagining exactly how this tech will be put to use is tricky, but a group of researchers from the University of St Andrews in Scotland are exploring its limitations. In a paper published last month, they show how Project Soli hardware can be used for a range of precise sensing tasks. These including counting the number of playing cards in a deck, measuring compass orientation, and…
