(Video) FTIR Touch Sensing

Not to be confused with Jeff Han's multi-input touchscreen, FTIR touch sensing "relies on frustrated total internal reflection (FTIR), a technique familiar to the biometrics community where it is used for fingerprint image acquisition". Video demonstration after the jump.
