In my last term at RIT, I took a course titled Innovation and Invention with Dr. Jon Schull. It was rather experimental, with a breakneck pace and minimal organization that was both highly productive and rewarding. It has continued to flourish, and has significant overlap with the new Collaboratorium at RIT.
As part of this course, I worked on a multitouch display (see my project log for the multitouch table). Matthew Kampschmidt and I gave a talk that introduces multitouch technology and applications, as well as the fundamentals behind FTIR (Frustrated Total Internal Reflection).
