Their approach uses an FTIR (Frustrated Total Internal Reflection) method, which is quite commonly used in the literature. Another technique, shown here by Paul Foster uses an IR rear-diffused method. I’m partial to FTIR because of its potential responsiveness, but I’m not sure if that’s born out in reality. Both approaches are great homebrew projects.

Both groups use software from the NUIGroup–a must have resource for any multi-touch experimenter.
