Abstract
In one aspect, an electronic system includes a source of an audio signal, a sound projector, an imaging system, and a controller. The sound projector is operable to generate at least one directed sound beam based on the audio signal. The imaging system is operable to capture images of a person in a space adjacent to the sound projector and to process images captured by the imaging system to identify at least one eye of the person and to estimate a position of the person in the space based on the identified ones of the person's eyes. The controller is operable to control the generation of the directed sound beam based on the estimated position of the person in the space.

An electronic system, comprising:
- a source of an audio signal;
- a sound projector operable to generate at least one directed sound beam based on the audio signal;
- an imaging system operable to capture images of a person in a space adjacent to the sound projector and to process images captured by the imaging system to identify at least one eye of the person and to estimate a position of the person in the space based on the identified ones of the person's eyes;
- and
- a controller operable to control the generation of the directed sound beam based on the estimated position of the person in the space.
A method of generating a directed sound beam, comprising:
- capturing images of a person in a space;
- processing the captured images to identify at least one eye of the person and to estimate a position of the person in the space based on the identified ones of the person's eyes;
- and
- generating at least one directed sound beam based on an audio signal and the estimated position of the person in the space.
