Gesture Interpretation on Beagle Board using high Freq soundwave

I am a 4th year student at NIT Raipur , I propose to build a Gesture recognition system for beagle using signal processing on audio to interpret gestures using only a soundcard and a mic. Which can then be used by community to create new gestural experiences on beagle

pls provide your views on draft

the apllication interfaces that i can promise are sound , volume , brightnes ,zoom scroll (pdf) , and ppts

the further devlopment section that requires OFDM is still not completely understood by me but will try my best to implement it.

what the project holds for Beagle Board . The both parts of proposal when integrated with IOT allows beagle to provide an intrerface to users to interact more immersively with their surroundings
