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-OS X. You'll see all the values sent by the Arduino Uno, the gesture events and the 3D coordinates in the form of a cursor.
What’s it used for?
3Dpad's technology can be used in a very wide field of applications, for instance: medical & healthcare (should reduce the nosocomial risk), household appliance control (think at cooking when your hands are covered of fat content), gaming with "air control", and many other.
At the moment my favorite app is music, using 3Dpad as an "3D Air control" MIDI controller.Watch our first experiment Video

Questions / Answers :
What are the possibilities for hiding the 3D-pad behind different materials? The electrode plan PCB can be covered with glass, plastic, ceramic, wood, textile, or any other insulating material See it in this video
Who designed the 3Dpad? 3Dpad is based on my own invention (I've got granted patents on it). The current version in the form of an Arduino shield has been designed in collaboration with the Elektor Labs. A full description is available in the Elektor magazine - May 2014 edition.

Does the "Ink"Color Bag have silver tone hardware? (Chain)? It is hard to tell in photo

I bought the black one and the chain is gold color. Not sure of the ink bag.

You need a WiFi Internet connection, and a smartphone or tablet for the Echo App. That's it. It is easy to set up, but it may take you a while to figure out all of the little things that the Echo App can do.

BEWARE this is NOT STEREO and it is NOT MONO. This is only one channel. You will not hear part's of songs (recorded in stereo) that are only played through the left channel. Kinda ridiculous. Still it is a decent sounding speaker.

★★★★★ Great bag
Purchased this for my 23 year old daughter in the butterscotch color. Great versatile color. She loves the size -- perfect for day or going out at night. Chain can be double to shorten for nighttime and left long to wear as a crossbody during the day.
