Project Soli from Google brings RADAR technology for gesture recognition in wearable devices
Gesture recognition is the
mathematical interpretation of the human motion by an
electronic device. The applications of gesture recognition are seen
wearable, smartphones, tablets,
televisions and gaming devices. Most
of the modern gesture technology is
or 3D-based which works with the help of camera enabled device placed in
front of an individual. Most of this technology is unreliable and the camera’s
motion tracking abilities are ineffective and less accurate. The camera based
gesture technology works poorly in low light conditions and when the camera
quality is low. To avoid this problem
Advanced technology and Projects Group
is working on
“Project Soli” that
provides a type of motion controller that uses small radar which picks up the
movements in real-time and uses these movements to alter the signals. Project Soli’s gesture tracking radar detects
objects in motion through high frequency radio waves that takes a fundamentally
different approach to motion tracking.
sensors capture motion up to 10,000 frames per second and are more accurate
than camera-based systems that track motion at much lesser frame rates. One
major disadvantage that users had with camera based gesture technology are that
in conditions of poor light and when obstacles are placed the cameras were not
able to track the motion making the gesture recognition weak. These radars can
pass through certain types of objects which make the technology more adaptable.
The radar technology gives high accuracy that is not possible with camera.
During the product demonstration Ivan Poupyrev the project lead for Project Soli primarily talked about Project Soli in the context of smart watches. The applications of radar based gesture recognitions are not just limited to wearables. The radar technology uses a small chip that can be embedded in any type of device and be used for varied applications. ATAP plans to open Project Soli to developers so that they could work on this technology and build their own applications for gesture controls. The company hasn’t announced yet as to when they want to make this technology available. The success or failure of this project primarily depends on the developer response and the interest from hardware manufacturers. The technology when commercialized could revive the falling android wearables sales.
