Computer student on gesture control: Start experimenting
Back in 2012, authors from Microsoft Research and UbiComp Lab at University of Washington prepared their paper, "SoundWave: Using the Doppler Effect to Sense Gestures," for the Proceedings of the Association for Computing Machinery's Conference on Human Factors in Computing Systems. Their work created a lot of interest in the way that they managed to implement motion sensing using only speaker and mic. Sidhant Gupta, Dan Morris, Shwetak Patel, Desney Tan said that "Gestures are becoming an increasingly popular means of interacting with computers. but—it is still relatively costly to deploy robust gesture-recognition sensors in existing mobile platforms." Enter their SoundWave, a technique that leveraged speaker and microphone for sensing in-air gestures and motion around a device.
