LED-LP 19" Widescreen Multi-touch LCD - First Tests

So, I've been to Japan and back, but now I've finally found the time to get back into some multi-touch projects I started some months ago. This is my first video of the LED-LP (LED-Light Plane) 19" Widescreen multi-touch LCD prototype I am building.

There are a total of 40 IR LED's around the LCD panel, a PS3 Eye Webcam mounted behind the LCD module, and tbeta running for the blob detection.

This video is of the tbeta main screen where the raw camera feed and applied filters can be seen.

(NOTE: There are some glitches/false inputs being detected and that is due to reflection of IR from the back acrylic onto the LCD's PCB. This can be fixed easily by covering the PCB with non-reflective material.)
