Apple to patent proximity sensing for TV audio, video chat
By Phil Dzikiy | 01.31.13

A newly revealed Apple patent application reveals a system that can adjust and enhance audio based on a user’s proximity to the device. While the application notes that the device could be a computer, tablet, or audio player, Apple also notes that it could be used for a television—and includes illustrations showing what appears to be a TV.

Operating as novel proximity sensors, a multiple microphone array and face detection processing could enable a video conferencing camera and mic to focus on one of multiple users. The system could also conceivably adjust audio based on the environment. “For example, echo cancellation may be desired and/or affected by the size and acoustics of the room,” the description reads, meaning that a small, carpeted room could receive different audio output than a large room with hardwood floors.
