The notions of gesture based systems are usually associated with gaming accessories such as Microsoft Kinect or computers with modules such as Leap Motion. But Google ATAP team found that users of smart watches need an easy way to control the device without having to use a smartphone. Project Soli is innovation, which will replace the old fashioned screens and buttons with simple hand gestures, using radar to capture movement.

The system works with the help of the guided wave radar to measure the Doppler image, IQ and the spectrogram. The chip detects motion, distance and speed. It can be programmed with different initial distance. The chip works within radar range of 60GHz, at up to 1000 frames per second. The finished chip will contain everything needed to be placed and operated with antennas. ATAP claim that the device could be released on a large scale.

The idea is that users can use some of the movements that they already use while working with a Smartphone, but enrich them with natural gestures of their hands to interact with devices supported by Soli.

How does it work?

The main driving force in Soliare are the human fingers. For example by sliding the thumb against index finger is the command for scrolling and by pinching them together the one to cancel the last action. ATAP are also trying to solve the problem of frequency interaction by providing a larger area using a touch-sensitive fabric.

The team of Project Soli still working on the finalization of the final product, but it is almost certain that the device size will range from pizza box size to ones with the size of an SD card.

Earlier this year’s during the annual developer conference Google I / O was the first official presentation of the project. But more details about Project Soliare known only to a few people in the company. The company has sent requests to the narrow circle of specialists who would likely be interested to in a alpha-Soli development kit (SDK). “It is very limited,” said a spokesman at Google. Then he added: “We are working on more advanced beta version, which will release at the end of this year.” But for now, the company does not allow any casual programmers to come close to its futuristic project.
