US 2010/0149310 A1 · VISUAL FEEDBACK FOR NATURAL HEAD POSITIONING

Abstract

A videoconferencing conferee may be provided with feedback on his or her location relative a local video camera by altering how remote videoconference video is displayed on a local videoconference display viewed by the conferee. The conferee's location may be tracked and the displayed remote video may be altered in accordance to the changing location of the conferee. The remote video may appear to move in directions mirroring movement of the conferee. This effect may be achieved by modeling the remote video as offset and behind a virtual portal corresponding to the display. The remote video may be displayed according to a view of the remote video through the virtual portal. As the conferee's position changes, the view through the portal changes, and the remote video changes accordingly.

Dependent claims

A method implemented by a near-end videoconferencing terminal for displaying far-end video on a display of the near-end videoconferencing terminal, the far-end video being provided by a far-end videoconferencing terminal connected with the near-end videoconferencing terminal, where a first person is using the near-end videoconferencing terminal to video conference with a second person using the far-end videoconferencing terminal, the method comprising:

automatically determining a position of the first person relative to the near-end videoconferencing terminal or a camera thereof;
modeling both a surface, and a view point corresponding to the determined position of the near-end person;
transforming the far-end video by the near-end videoconferencing terminal, where the transforming is based on the modeled view point and surface;
displaying the transformed far-end video on the display of the near-end videoconferencing terminal.

One or more computer-readable storage media storing information configured to transform a videoconferencing device to perform a process, the videoconferencing device comprising a display displaying remote video from a remote videoconferencing device, the video conferencing device providing to the remote videoconferencing device video captured by a camera of the videoconferencing device, the process comprising:

tracking a changing location of a person who is using the videoconferencing device;
computing a model of a three-dimensional scene, the three-dimensional scene comprising a bounded first plane, a point having a location in the three-dimensional scene that changes in correspondence with the tracked changing location of the person, a second plane substantially parallel to the bounded first plane and arranged between the point and the bounded first plane, and a projection of the bounded first surface that changeably converges to the changing location of the point;
and
fitting the remote video to a graphical display area displayed on the display, where the graphical display area is determined by an intersection between the projection and the second plane, the graphical display area changing in accordance with changes in the intersection resulting from changes of the location of the point.
