3Dpad touchless gesture controller Arduino shield by ootsidebox

This will change the way we interact with our devices and technology! Ootsidebox's 3Dpad will expand the arduino communities reach and possibilities opening a new door to interaction. I can't wait to see what makers will create with this amazing shield. If you decide to back them Please use this link, please leave a comment on their campaigns comment page that you found their project through , Thank you.

Our vision: 
"Touchless and gesture control everywhere and for everyone!"

But not provided by a big company like Microsoft, Samsung, Apple or similar.

Easily make your own with 3D-Pad!

What is 3D-Pad, and how does it work?

3D-Pad is a touchless gesture control interface providing 3D coordinates and gesture recognition, with a 10cm depth perception.

It consists of a sandwich made up of: 
  • a PCB called an electrode plane (1)
  • an  Arduino Shield (2)
  • an Arduino Uno (3) - based on ATMEL ATmega328

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 following signal processing is used:
  • a phase/frequency comparator
  • a control and locking program
This simple system makes the conversion of the very small frequency shift into a variation in a voltage signal which is easy to use:

The embedded software 
(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 (PC) will enable you to quickly evaluate the 3D-Pad. You'll see all the values sent by the Arduino Uno (1), the gesture events (2) and the 3D coordinates in the form of a cursor (3).

We designed the first prototypes with our partner Elektor Labs

Why do we ask for your support?

3Dpad is only the starting point for OOTSIDEBOX: 
We have many other ideas to share in the field of human - machine interaction: touchless & gesture interfaces, telehaptics, wearable technology, artificial intelligence and many more. We are sure you will love it!

Your support in this Indiegogo campaign is the key to start OOTSIDEBOX right now.

We have rewards for you:

Limited edition of our special design T-shirt

 Jean-Noël - the inventor - says:
"The story started six years ago with my basic invention. For one year now I have been working full time on it to finally get it to market.
The idea of this disruptive technology is to enable humans to interact with electronical devices by touchless and gestural mode. 
Ootsidebox is in competition with very big companies. However, we are able to give benefits that they cannot provide so far. I´m very proud of this fact and today we want to share it with all the creative people: artists, makers and hackers".

Feel free to share!
