System and method for dynamic control of audio playback based on the position of a listener
First Claim
1. A system with a multi-channel audio sound system that dynamically adjusts audio playback, the system comprising:
- an input device operable to receive an entry of initial set up data, wherein the initial set up data includes a definition of an out of bounds response and a listening area within a room;
a sensor operable to track an orientation of a portion of interest of a listener and a location of the listener;
a processing module, operable toreceive data corresponding to the orientation of the portion of interest of the listener and the location of the listener,determine whether the location of the listener is within the listening area, andgenerate, in response to the location of the listener being within the listening area, an adjustment signal based on the orientation of the portion of interest of the listener; and
an audio module operable to;
receive the adjustment signal and to produce an audio signal for each channel in the multi-channel audio sound system and to control audio playback of the audio signals by the channels in the multi-channel audio sound system, andinitiate, in response to the location of the listener being outside the listening area, the out of bounds response.

Abstract
An optimal listening position for the multi-channel audio sound system is determined. A listening area and other audio playback controls may also be defined or modified by a listener. During subsequent audio playback, an imager captures images of at least a portion of the listener. When the listener has moved to a position that is different from a previous position, one or more audio parameters are adjusted for at least one channel in the multi-channel audio system in order to reposition the initial or previous optimal listening position to the current position of the listener. When the listener moves outside the listening area, an out of bounds response is initiated to disable or control the audio playback until the listener moves to a position within the listening area.

5. A system with a multi-channel audio sound system that dynamically adjusts audio playback, the system comprising:
-
an input device operable to receive an entry of initial set up data, wherein the initial set up data includes a definition of an out of bounds response and a listening area within a room; a sensor operable to track an orientation of a portion of interest of a listener and a location of the listener; a sensor processor operable to receive data corresponding to the orientation of the portion of interest of the listener and the location of the listener, determine whether the location of the listener is within the listening area, and store the determination in a memory; a controller operable to read the determination out of the memory, and generate, in response to the location of the listener being within the listening area, an adjustment signal based on the orientation of the portion of interest of the listener; and an audio processor operable to; receive the adjustment signal and to produce an audio signal for each channel in the multi-channel audio sound system and to control audio playback of the audio signal by the channels in the multi-channel audio sound system, and initiate, in response to the location of the listener being outside the listening area, the out of bounds response. - View Dependent Claims (6, 7, 8, 17, 18)

9. A method for dynamic control of audio playback in a system having a multi-channel audio sound system, the method comprising:
-
receiving initial set up data, wherein the initial set up data includes a definition of an out of bounds response and a listening area within a room; capturing data corresponding to an orientation of a portion of interest of a listener and a location of the listener; determining whether the listener is within the listening area; and when the location of the listener is within the listening area; generating an adjustment signal based on the data corresponding to the orientation of the portion of interest of the listener, producing an audio signal for each channel in the multi-channel audio sound system, and controlling audio playback of the audio signal by the channels in the multi-channel audio sound system based on the adjustment signal, and when the location of the listener is outside the listening area, initiating the out of bounds response. - View Dependent Claims (10, 11, 12, 13, 14, 19, 20)
