摘要：This paper presents a proposal to tackle the design and development of user
interfaces for groupware applications. This proposal includes important design
and implementation issues of special relevance for this kind of interfaces. In
particular, group awareness requirements in the development of groupware
applications are addressed, both in the sense of the basic manipulation actions
of the interface widgets, as well as in the sense of other kinds of group
awareness in relation to the presence of actors, the roles they play in a
concrete moment, etc. The design proposal we present is part of a complete
development process (called TOUCHE) which defines a set of facets to describe
Abstract Interaction Objects. These objects, at design level, provide the basis
for the definition of Concrete Interaction Objects at implementation level
within a software platform intended to facilitate the development of user
interfaces for groupware applications. This way, we get an integral approach to
tackle the development of this kind of user interfaces, taking into account in
an explicit way the perception of the joint activity of a group of users
involved in a common task and thus achieving a more effective collaboration.
