Introduction 1-5

The Videoconferencing market is growing rapidly with the more widely available ISDN network and cost effective videoconferencing units such as VisuaLink. Videoconferencing is being adapted to a wide variety of applications.

•General Business provides many applications for videoconferencing between distant sites. New opportunities are possible, especially for small groups of people where videoconferencing was too complex or costly before. Smaller project meetings and reviews could now use videoconferencing. Project members or staff “on-the road” could participate using their Laptop PCs (with VisuaLink, video capture card, camera, and BRI interface).

•Education provides significant opportunities for in-home instruction, special needs tutoring, at-home corporate training, remote product training, and remote technical assistance for product maintenance.

•Remote Interactive Kiosk is possible for public offices, consumer retail, remote site-seeing guides, remote consultation, remote convention & trade show expertise and presentations.

•Telemedicine creates the opportunity for in-home care giver to senior citizens or the mobility impaired. Remote medical training for hard-to-get-to locations or smaller medical centers.

•New Applications - New Markets will now be opened and realized with VisuaLink. VisuaLink compact systems can be setup at any location for presentations and interactive communications. It can instantly bring in experts (from back home) to help the sales force at a remote convention.

The following diagrams illustrate some of the various uses for VisuaLink videoconferencing.
