Digitimes Research published a nice map of interface technologies battling for the next generation TV control:
Some of these technologies are based on sensors and optics. Primesense uses structured light 3D camera. Softkinetic and PMD use ToF cameras. Philips relies on IR triangulation for its motion sensing remote.
