I'm working on arduino based project, that actually can perform 3 features:

1. Virtual Touch Screen, for remote control purposes big screen TV, projectors, public display, or for interactive games
2. 3D Ultrasonic Radar, small range - 3 m for now, but real time with update rate 50 fps;
3. Precise distance measurements , down do 12 micrometers.

FFT is the major part of software application running on arduino DUE (cortex-3 , ATMEL SAM3X8E), plus 4 very popular ultrasonic distance sensors HC-SR04. Extracting the phase of returning ultrasonic wave, great precision in distance measurements possible.

More details on the blog page:

and two demo video clips on youtube channel:
