Communication workstations for B-ISDN: MONSTER (multimedia oriented super terminal)

Hajime Kamata; Tsuneo Katsuyama; Toshimitsu Suzuki; Yu Minakuchi; Katsutoshi Yano

The authors describe the human interface for broadband multimedia communication services to be provided for use with the broadband integrated services digital network (B-ISDN). The basic architecture of a B-ISDN terminal called MONSTER (multimedia oriented super terminal) for realizing the human interface is also described. This terminal can transfer multimedia data at a rate of 150 Mb/s and process them in real time.<<ETX>>

The human interface in a multifunctional communication terminal

Hajime Kamata; Akihiko Obata; Motomitsu Adachi; Shuzo Morita

An intelligent human interface for a multimedia communication terminal, the Imagephone, is presented. Its adaptive user interface control system (which adjusts the timing of messages to the users ability) and its object-oriented software are described. The interface of the Imagephone proved efficient for a small communications terminal, but there is room for expansion. The object-oriented approach was found to be very effective. Use of C and a general-purpose operating system make the step from prototype to a commercial product a simple one. >

THE HUMAN INTERFACE IN A MULTIMEDIA COMMUNICATION TERMINAL

Hajime Kamata; Akihiko Obata; Motomitsu Adachi

New multimedia communication networks such as ISDN and office Automation communication systems are being rapidly introduced into existing communication networks. Easy-to-use human interfaces are important to bring out the full potential of these advanced networks. This paper describes the human interface in a multimedia communication terminal, the Image Station.
