What is Project Soli:
Soli is a new sensing technology of Google's latest cutting-edge experiments from its secretive Advanced Technology and Projects group (ATAP) that uses miniature radar to detect touch-less gesture interactions. The Soli chip incorporates the entire sensor and antenna array into less than size of a coin and operates at low power. Google's Advanced Technology and Projects group (ATAP) is a skunkworks team similar to X. ATAP team was born at Motorola but during Motorola sold to Lenovo, Google opted to keep ATAP.
How Does it Work:
Soli sensor works by emitting electromagnetic waves in a broad beam. It differentiates the gestures with different energy emits, signals, time delay and frequency shift. These are calculated through size, shape, orientation, material, distance and velocity, which are accomplished with the motions from fingers and hands. Google uses different hardware, software and algorithms to develop soli. It implements several layers/stages of signal abstraction with machine learning, detection and tracking algorithms.
Why is it Different:
Soli has gestures that mimic virtual tools as physical tools. Even though these controls are virtual, the interactions feel physical and responsive. Feedback is generated by the hap-tic sensation of fingers touching each other. Without the constraints of physical controls, these virtual tools can take on the fluidity and precision of our natural human hand motion. Soli has no moving parts, it fits onto a chip and consumes little energy.

Where can Soil be used:
As if we don't know exactly when does Google is going to bring it out to the market nonetheless the Soli chip can be embedded in wearables, phones, computers, cars and IOT devices in our environment. If you seen Iron-man movie tony virtually controls everything through his hands. If Google perfects this, it's one step towards it.
