Abstract

A collaborative information processing system is formed of a plurality of terminal units interconnected through a network. Each terminal unit includes a microprocessor provided with a control program for controlling the execution of various application programs and the communication with other terminal units, input/output devices such as a display unit with a display screen and keyboard, and a telephone set. A plurality of users join in a conference or such a group work to create materials by making reference to a material which is displayed equally on the screen of each terminal unit and making conversation through the telephone set under control of the control program. Records of group work information including the outline of the group work, names of participants, and names of materials and data created or referenced during the group work or conference are stored automatically in a database so that the records can readily be retrieved in the future.
