Abstract

Systems and methods for performing teleinteractive video teleconferencing between two or more teleconference sites, and for enabling any number of teleconference sites to overlay a pointer to point within the video image originating from any teleconference site. The systems and methods employ at least one video imaging device to capture images at a local teleconference site and N display devices to display images captured at the local and the remote teleconference sites, where N is the total number of teleconference sites comprising the system. The teleinteractive capability is accomplished when a local teleconference site selectively inputs the video imaging signal from a remote teleconference site into a pointer overlay device rather than the local video image. The pointer overlay device then overlays the pointer and the overlaid video signal is then transmitted to the remote teleconference sites. Finally, by providing remote control means to actively position the video imaging device at a remote site, the position of the overlaid pointer within a displayed image can be used to reposition a video imaging device at a remote teleconference site.
