Project Soli is a new gesture-recognition technology based on radar, unlike established approaches based on visual or infrared light such as stereo cameras, structured light, or time-of-flight sensors. This novel approach, which uses small, high-speed sensors and data-analysis techniques such as Doppler, can detect fine motions with sub-millimeter accuracy. Thus, for instance, Project Soli technology enables a user to issue commands to a computer by rubbing a thumb and forefinger together in pre-defined patterns. Applications might include sensors embedded in clothing, switches that don't require physical contact, and accessibility technology.
The project is headed by Ivan Poupyrev, a former scientist for Disney Imagineering who was named one of Fast Company's "100 Most Creative People in Business 2013". Project Soli was announced at Google I/O 2015 and generated considerable media interest. According to the official site, in 2015 the team was preparing to make an alpha Project Soli development kit available to a limited number of developers, with plans for signing people up for a larger beta release later that year.
This technology would help smartphone's face recognition capabilities. This would enable smartphone to unlock it by using a radar at a specific frequency to sense that owner is near it and it would unlock it by recognizing the face at a specific angle. This Technology could revolutionize smartphone face recognition security.
