Abstract
In a particular illustrative embodiment, a method of determining a viewpoint of a person based on skin color area and face area is disclosed. The method includes receiving image data corresponding to an image captured by a camera, the image including at least one object to be displayed at a device coupled to the camera. The method further includes determining a viewpoint of the person relative to a display of the device coupled to the camera. The viewpoint of the person may be determined by determining a face area of the person based on a determined skin color area of the person and tracking a face location of the person based on the face area. One or more objects displayed at the display may be moved in response to the determined viewpoint of the person.
