Touchless 3D Tracking
===================
----
This is based on an original project by [Kyle Mc Donald](https://github.com/kylemcdonald) : http://www.instructables.com/id/DIY-3D-Controller/.
Our slightly adapted setup is documented on my hacklab website [hackens.org](http://hackens.org/). All the documentation can be found here : **(documentation to be written)**.
Our slightly adapted setup is documented on my hacklab website [hackens.org)](http://hackens.org/) (in french, I may write english doc if some people are interested in that). All the documentation can be found here : http://hackens.org/Projets/TouchlessTracking **(in french, documentation will be written soon, after some extra tests)**.
In this repository, you'll find :
......@@ -30,21 +29,40 @@ You'll also find some basic Python scripts as examples on possible use of the se
This script represents the position of your hand in the RGB space. You can then pick a color by placing your hand at a specific point in the box of the electrodes.
### Chorizo.py
__(working on)__
A script to play music using chorizo pads as a musical keyboard. See [our website](http://hackens.org/Projets/TouchlessTracking) (french, but vids are available, more coming soon) for infos and demos.
### 3d_view.py
__(working on)__
Same as _colors.py_ but represents the position in real space (cube view) rather than in RGB space.
### Some ideas (TODO List)
* Same as colors.py but representing it with a 3D view.
* Then, use the previous code as a control interface for your computer, just like Minority Report :)
* Other ideas ? It's up to you :)

# scripts (but try to have fun :), I don't mind. It would be cool to quote
# the origin of the script if you reuse it, but you don't have to. I'd like to
# be noticed of what you did cool with it (if you think it's worth). :)
# Ah, I almost forgot : If by chance we ever meet and you think this script is
# worth, you can buy me a soda :)

TLDR; I don't give a damn to anything you can do using this code. It would just
be nice to quote where the original code comes from.

## Thanks
* `Baltazar` from hackEns for his help to set it up and for the original idea.
* [Kyle Mc Donald](https://github.com/kylemcdonald) for his documentation on his setup
* [PRKTRNIC](http://vimeo.com/68763028) (video in french) for the idea about playing music with chorizo and sausages !
