Abstract

A 2D and/or 3D video processing device comprising a camera and a display captures images of a viewer as the viewer observes displayed 2D and/or 3D video content in a viewport. Face and/or eye tracking of viewer images is utilized to generate a different viewport. Current and different viewports may comprise 2D and/or 3D video content from a single source or from different sources. The sources of 2D and/or 3D content may be scrolled, zoomed and/or navigated through for generating the different viewport. Content for the different viewport may be processed. Images of a viewer'"'"'s positions, angles and/or movements of face, facial expression, eyes and/or physical gestures are captured by the camera and interpreted by face and/or eye tracking. The different viewport may be generated for navigating through 3D content and/or for rotating a 3D object. The 2D and/or 3D video processing device communicates via wire, wireless and/or optical interfaces.

Claims

1. A method for communication, the method comprising:

performing by one or more processors and/or circuits in a 2D video and/or 3D video processing device;

capturing one or more images of a viewer as the viewer observes 2D and/or 3D video content that is displayed in a current viewport;

performing face and/or eye tracking on said captured one or more images of said viewer;

generating a different viewport comprising different and/or partially different 2D and/or 3D video content based on said face and/or eye tracking; and

displaying said generated different viewport.
