★★★ Control the bird without ever touchingyourdevice! This app uses a classic game to illustratetheSoundWave motion sensing concept. ★★★Similar to the idea of the SoundWave gesturedetectiontechnique published in Microsoft Research, this game usesyourdevice's speaker to generate an inaudible tone, and usesyourdevice's microphone, along with the physics of theDopplerEffect, to detect your motion.How It Works:1) The program generates an inaudible 20 kHz tone fromyourdevice's speaker.2) It uses your device's microphone to monitorthesound.3) Using the mathematics of the Fourier Transform,itdetermines the spectrum of frequencies contributing to themeasuredsound.4) When you move your hand toward the microphone, the 20kHzfrequency is shifted higher in accordance with the DopplerEffect,allowing the program to detect your hand motion.How To Play:✔ Make sure your device's volume is on✔ Keep your device as still as possible for maximum accuracy✔ Move your hand toward your device's microphone to movethebird.✔ Keep your hand still when you don't want the birdtomoveNotes:This has only been tested on a very limited number of devicesatthis point, so results may vary.The network permission is for Google Play GamesServices:leaderboards, achievements, etc.The original SoundWavepaper:http://research.microsoft.com/en-us/um/redmond/groups/cue/publications/guptasoundwavechi2012.pdfMore information about / implementations of thisidea:https://github.com/DanielRapp/doppler
