The ability to effectively teleconference between multiple sites has become a more important aspect of business as the cost of travel has increased. The coordinated use of local/remote pointer functions and local/remote viewpoint control functions in a telecommunications circuit is termed teleinteraction.


This invention expands the techniques and technology of teleconferencing through the innovative use of a teleinteraction circuit layout. These concepts of end-to-end pointing, and end-to-end viewpoint control are introduced by this technology. These new functions enable major improvements over traditional teleconferencing when doing end-to-end tasks, such as instruction and coaching. The circuit allows for two or more sites of interaction to be used simultaneously. The circuit allows for interaction between the sites by use of a two-way pointer, this is referred to as end-to-end pointing. The two-way pointers enable a site to not only identify objects in its own environment, but also to identify objects in any of the other sites' environments. Two-way viewpoint control enables any site to shift to any other sites viewpoint, this is referred to as end-to-end viewpoint control.

Applications and Advantages


  • Coaching and instruction of new techniques and skills


  • End to end viewpoint and pointer control
  • Easily integrated into existing teleconferencing links
