Google introduced a new product called Project Soli, which uses radar technology to detect movements to such a detailed degree that you can use subtle finger movements to control it.
The technology can capture 10,000 frames per second, an unprecedented level of information processing to be put into such a small chip.
“What is most exciting about it is that you can shrink the entire radar and put it into a tiny chip,” Ivan Poupyrev, Project Soli Founder, said. “That’s what makes this approach so promising: it’s extremely reliable. There is nothing to break, no moving part, no lenses, just a piece of sand on a board.”
