Pedro A. Antunes, Nuno Guimarães · 1996
This paper describes a user-interface system developed to support group interaction for same-time/different-place cooperative applications. The user-interface system is based on a model which defines four types of objects, each one dedicated to address a specific issue of group interaction support: information sharing, interaction control, structuring of group interactions and awareness of user activities in the system. Examples of combination of the above objects are given for the implementation of talk, joint editing and telepointer services. 1 Introduction The computer support to group interaction consists of three basic functionalities: information sharing, control and user-interface. Information sharing allows to establish a common context between individuals. This functionality requires the specification of a data consistency model. Data consistency can be preserved through concurrency control mechanisms [7], e.g. locking, versioning, history, views, etc. Group interaction add...
