3Dpad - touchless gesture controller Arduino shield
Make your own touchless control interface providing 3D coordinates and gestures with a 10cm depth perception, in the form of an Arduino shield.
3Dpad is an innovative and experimental system that you can use for creativity, experiments and education.
To detect the proximity of the human hand or finger, we are using the projected capacitive technique. This is the principle of virtually all modern touch screens - except that now we are in the air, relatively far away from the detector surface (10 cm max).
