nference Rooms Room-size video conferencing systems have long been touted as a way to cut down on travel and improve communication between remote offices, business partners, and customers. However, not all room-size systems have been adopted successfully. Impediments to Room-Size Video Acceptance Sometimes, acceptance and use of room-sized systems can probably best be described as disappointing. These less-than-successful implementations are examples of how technology alone does not guarantee adoption. Also vital are lease of use and training. The following are some other reasons for low usage. Lack of Quality of Service (QoS) in the network, resulting in poor video and audio quality. Insufficient bandwidth (capacity), also resulting in poor-quality video. A combination of inadequate user training and video systems that are dif- ficult to set up. Participants often do not know how to set up the conference or share documents or graphics with remote participants. Poor camera use, such that the distant participants' heads are indistinguish- able from one another or whose expressions are not clearly visible. The Growing Interest in Group Video Conferencing Newer video equipment that is easier to use, provides higher-quality resolution, and operates on IP networks has resolved some of these problems. The use of public rooms and carriers' managed services for video conferences can also lessen problems. More- over, improved wide area networks (WANs) and specially designed conference rooms, in combination with economic factors, together with technological improvements in video, have sparked renewed interest in all types of conferencing. A number of additional factors are raising the interest of many organizations in using group video conferencing for meetings. These include saving money on travel; speeding up projects and decision making by making it easier for groups to discuss issues in real time; interactive modes; and people's positive experiences with resi- dential desktop video services, such as those offered by Go
