GRAPHICS & INTERACTION SEMINAR
GB221, at 3:00 p.m., Tuesday 31 October 1989
Mr. Hiroshi Ishii
NTT Human Interface Labs
"Cooperative work Models and Groupware"
Mr. Ishii will discuss the cooperative work models which capture the
dynamic structure of a cooperative activity and provide a framework for
groupware design. First, the concept of "groupware" and its impacat on the
traditional view of "human interface" is presented. Second, COOKBOOK, a
research project integrating office procedure modeling, procedure execution
techniques, and knowledge-based problem solving techniques is introduced.
Third, a six-level framework of group interaction structures is proposed to
clarify the current issues of cooperative work models and the design of
seamless groupware. From this proposal, the next goal of cooperative work
modeling is to incorporate the weak procedural structure and role concept
into the conversation network.
"TeamWorkStation: SHAREABLE DESKTOP WORKSPACE FOR COLLABORATION"
TeamWorkStation is an approach to the utilization of computer-mediated
communication technology to provide shareable workspaces for small groups
of 2 to 5 members. TWS design is based upon the key idea of overlay. This
allows users to combine individual workspace images and work together in
the shared workspace. Overlay leads to another key idea: seamlessness.
Seamlessness refers to the elimination of all conceptual gaps between
individual and group work practices as crucial to the consistent and smooth
support for cooperative work. In a TWS environment, users can shuttle
easily between the shared workspace and their individual workspace. The
key design concepts of TWS: overlay, seamlessness, and a shared drawing
surface; the implementation methods of TWS, and some results of
experimental use will be described.
