This publication contains more than 50 papers on the latest developments and applications of interactive media to link distant locations. The contributors, who represent business, government, education, medical, and telecommunications organizations in the United States, Canada, England, and Australia, have had direct experience with the full range of interactive systems including audioconferencing, audiographics, slow scan televideo, full motion video conferencing, computer conferencing, computer messaging systems, and videotex service. Further, they have used all channels to reach distant locations, i.e., telephone, cable, microwave, and satellite. The intent of the publication is to give a perspective on the field from the vantage points of the user, administrator, instructional designer, researcher, technical designer, and product manufacturer. The papers are grouped in five categories: Teleconferencing in Business and Government, Teleconferencing in Education, Teleconferencing in Health and Medicine, Program Design and Research, and Computer Conferencing and Messaging Systems.
