Three-dimensional audio sweet spot feedback
First Claim
1. A method for providing three-dimensional audio, comprising:
- receiving a depth map imaging a scene from a depth camera;
recognizing a human subject present in the scene;
modeling the human subject with a virtual skeleton comprising a plurality of joints defined with a three-dimensional position;
determining, based on the virtual skeleton, a world space ear position of the human subject;
determining a target world space ear position of the human subject where a desired audio effect is produced via an acoustic transducer array; and
visually indicating a three-dimensional spatial relationship between the world space ear position and the target world space ear position.

Abstract
A method for providing three-dimensional audio is provided. The method includes receiving a depth map imaging a scene from a depth camera and recognizing a human subject present in the scene. The human subject is modeled with a virtual skeleton comprising a plurality of joints defined with a three-dimensional position. A world space ear position of the human subject is determined based on the virtual skeleton. Furthermore, a target world space ear position of the human subject is determined. The target world space ear position is the world space position where a desired audio effect can be produced via an acoustic transducer array. The method further includes outputting a notification representing a spatial relationship between the world space ear position and the target world space ear position.

15. A three-dimensional audio system, comprising:
-
a depth camera input to receive a depth map imaging a scene from one or more depth cameras; an audio input to receive audio input information; an audio output to provide three-dimensional audio output information to an acoustic transducer array comprising one or more acoustic transducers; a logic subsystem; and a storage subsystem storing instructions that are executable by the logic subsystem to; receive the depth map; recognize a human subject present in the scene; model the human subject with a virtual skeleton comprising a plurality of joints defined with a three-dimensional position; determine, based on the virtual skeleton, a world space ear position of the human subject; determine a target world space ear position of the human subject where a desired audio effect is produced via the acoustic transducer array; and output a notification representing a three-dimensional spatial relationship between the world space ear position and the target world space ear position. - View Dependent Claims (16, 17, 18)
