Apple’s tech would allow Kinect-style recognition to be more forgiving of less-than-ideal conditions, meaning it would make gesture interaction theoretically less painful for users, and therefore more likely to be used at all. The key innovation Apple made with the iPhone’s interaction model was getting touch-based input right – its capacitive screens and rigorously engineered touchpoint response was completely unlike the kludgy resistive touch-based experiences customers were used to.
In 2013, Apple acquired PrimeSense, the company which powered much of the tech that went into the original Kinect sensor. Some speculated at the time that Apple might be interested in using PrimeSense tech to add gesture-based input to Apple TV, among other possible uses. Apple successfully transferred PrimeSense patents to itself last year, and this new one contains key ingredients for improving the accuracy and efficacy of gesture recognition over time.
