Notes on construction of a internal reflection infrared rear projection touch table.
Projection/Touch Surface
Start off with a 4:3 aspect ratio so we can use a regular XVGA projector (1028x768).
A small table would have a projection area of 32" x 24"
A larger table would have a projection area of 48" x 36".
Table Frame Design
Could use a drafting table.
Multi-Touch Software
