Abstract:
1. A method of regulating volume, the method comprising: receiving a stream of depth images generated by an arbitrarily-placed depth camera imaging a three-dimensional world space from a singular vantage point; recognizing from the stream of depth images a position of a listener in the three-dimensional world space; tracking a position of the listener within the three-dimensional world space in a plurality of depth images; for each of one or more speakers within the three-dimensional world space, identifying in the plurality of depth images a three-dimensional position physically indicated by the listener and recognizing that three-dimensional position as the three-dimensional position of that speaker; tracking a position of a listener relative to each of the one or more speakers within the three-dimensional world space; for each of the one or more speakers, assessing a changing distance between that speaker and the listener in the three-dimensional world space; and automatically adjusting a volume of each of the one or more speakers in real-time based on a current distance between each respective speaker and the listener.
