Project Soli is using radar to enable new types of touchless interactions -- one where the human hand becomes a natural, intuitive interface for our devices. The Soli sensor can track sub-millimeter motions at high speed and accuracy. It fits onto a chip, can be produced at scale, and can be used inside even small wearable devices.It can be part of furniture, part of cars, a wearable computer, a watch, toys - anywhere people want to connect with devices it will be useful.
The beauty of Google's system is that it uses invisible radar emanating from a chip that can be embedded into just about anything.
In a nutshell it can be said that it would be the best invention of the decade which will allow us to interact more precisely and personally with our devices and will completely change the way in which we use our devices.
As this soli chip is very small in size so we can expect we will soon find it in every single device and gadget we are surrounded with.
