Microsoft is going to launch a new
technology called SoundWave for audio and video applications. This is the
result of the Microsoft latest project research that create a gesture controls
using a computer's speaker, microphone and inaudible sounds. This technology
implement doppler effect to detect the gesture. SoundWave have the ability to
detect the gesture from the lot of the background noise and detect the
frequently changes of sound wave with the help of inaudible sound and measuring
the change in the feedback as a hand gesture performed.
