Multitouch input has been spreading throughout a huge variety of devices, from phones to all-in-one PCs. However, most multitouch displays that can function with your computer tend to be fairly expensive, so with this project we're going to make our own display, that can run on any operating system, and reuses some used/now useless materials.

Concept:
The image processing software analyzes infrared light from the web camera and treats any light detected as a separate input source. Then this software sends the data to any other applications that have the ability to use the input (like a google maps plug-in). The multitouch table simply acts as a device that sends out IR light beams, so when a fingertip incepts them it appears as if the fingertips are producing infrared light.
