3Dpad touchless gesture controller Arduino shield

Availability: Retired

Introduction: Make your own touchless control interface providing 3D coordinates and gestures in the form of an Arduino shield 3Dpad is an innovative and experimental system that you can use for creativity, experiments and education. The underlaying technology is patented and can be used freely under Creative Commons licence CC BY-NC-SA.   It consists of a sandwich made up of: a PCB called an electrode plane (1) an Arduino Shield (2) an Arduino Uno (3) - *not included, you should use your own Arduino Detection principle: 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). It’s very simple: We build capacitors which are as “open” as possible, using electrodes drawn on the electrode plane PCB in order to obtain a maximum “hand effect”. The capacitors formed by the electrodes are part of an oscillator whose frequency is influenced by the distance of a hand. When it enters the electrostatic field, this “intruder” is going to cut the field lines and divert the electrical charges. Result: the closer the hand approaches the electrodes, the more the oscillator’s frequency increases. The embedded software The sketch running on the Arduino UNO will exploit the analog result in order to: Calculate 3D coordinates Recognize basic gestures (swipes, push and rotations) Send it all to a host device on the USB COM port The evaluation software Despite the fact that everything is calculated on the Arduino board, it can be usefull for you to have a software for a quick evaluation of 3D-Pad.   It's available in the form of a VB6 which (often) accepts to be installed under Windows. There is also a new one, made with  Processing. This is more confortable and runs under Windows, Linux an MAC-O
