Abstract

A system having a video display screen that provides video to a user. The position of the display screen is adjustable based upon the location of the user with respect to the display screen. The system includes at least one image capturing device trainable on a viewing region of the display screen and coupled to a control unit having image recognition software. The image recognition software identifies the user in an image generated by the image capturing device. The software of the control unit also generates at least one measurement of the position of the user based upon the detection of the user in the image.

Claims

1. A system having a video display screen that provides video to a user, the system comprising at least one audio capturing device that captures audio input from a viewing region of the display screen and coupled to a control unit having speech recognition software that identifies one or more audio commands spoken by a user in the viewing region, the control unit invoking an adjustment of the orientation of the display screen based upon the identified audio commands received from user.

2. The system of claim 1, wherein each of the one or more audio commands are correlated to movement of the display screen in a pre-determined direction.
