This Page Intentionally Left Blank EVALUATING AND BUYING A PERSONAL CONFERENCING SYSTEM There is science and applications of science, bound together as the fruit of the tree which bears it. Louis Pasteur he successful application of personal conferencing technology starts with the question, "What are we trying to accomplish" and continues with the question, "What does success look (and sound) like?" Chapter two and the product categories in the previous chapter can help define how one will use personal conferencing. If the purpose is to support communications between graphic artists or architects and their customers, products must focus on the presentation of visual materials (screen sharing). If visual cues such as facial expression and body language will enhance the exchange, one might consider videoconferencing. If the goal is to foster collaboration in a distributed workgroup, one might explore applications sharing and document collaboration tools. Most personal conferencing offerings exist as part of a product family. At the low end, the package may include whiteboard or screen sharing capabilities. The next step up might add a document collaboration utility. Moreover, by adding a camera, a microphone, speakers, and one or more PC boards, one might obtain videoconferencing functionality. Other enhancements might include gateways that link LAN-video packages to circuit-switched digital systems or video servers for store- and-forward broadcast applications. When developing an application, it is best to start with what is most necessary, and add features and capabilities as possible. People will probably have to change their habit
