This site is no longer being maintained! I have not been affiliated with NYU since 2006, when I founded Perceptive Pixel Research Interests: I am a consulting research scientist for NYU's Department of Computer Science, currently working with Yann Lecun on various autonomous robot navigation projects, while also finding time to direct some of my own research.
Over the years, I've also worked with several other professors at Courant, including Ken Perlin on great projects like the Kaleidoscope, with Denis Zorin on mesh simulation, and with Chris Bregler on motion capture. Jeff Han: Unveiling the genius of multi-touch interface design. Digital Stratum - FTIR Multi-Touch Surface. Frustrated Total Internal Reflection (FTIR) From NUI Group Community Wiki Background FTIR stands for Frustrated Total Internal Reflection.
It is a name used by the multi-touch community to describe the multi-touch methodology developed by Jeff Han (Han 2005). The phrase actually refers to the well-known underlying physical phenomena underlying Han’s method. Total Internal Reflection describes a condition present in certain materials when light enters one material from another material with a higher refractive index, at an angle of incidence greater than a specific angle (Gettys, Keller and Skove 1989, p.799).
