I don't think this has anything to do with Apple TV or gestures on tablets. IMO, those are gimmicky applications of the technology that look cool but aren't practical on a daily basis. My guess is that Apple is making an augmented reality play, hedging that Google Glass will be successful and they'll have to compete with them. Infrared motion tracking has a lot greater potential to be successful in augmented reality versus the single camera setup Glass uses.
