A 3D file explorer based on cheap computer peripherals (a usb webcam and a leapmotion) that simulates a 3D world where you can drag and drop files with natural hand gestures.

How to install dev environment for Linux (Ubuntu)
Install opencv (V2.4.8): http://miloq.blogspot.fr/2012/12/install-opencv-ubuntu-linux.html
to uninstall opencv go to the build dir and type "sudo make uninstall" (sudo needed to remove from /usr/bin etc.)
Install Qt 5.2: http://qt-project.org/downloads
Open Qt project: open holotouch.pro with qtcreator. It will create holotouch.pro.user, don't add it on git, it's generated by Qt
Leapmotion software for linux: go to https://developer.leapmotion.com/downloads and download the latest sdk for linux. You also need to install leapmotion software (drivers) on the same page. Install Leap-1.0.9+8411-x64.deb (or x86 depending on architecture). Then when your computer starts it will automatically launch leapd service. To verify it works just launch Visualizer in a terminal
The sdk is for developping applications, useful files are already included in this depot.
