Abstract

COLLABORATION is one of the major requirements intoday’s life and business. We can find collaborative activitiesat different levels and with different extents. The range ofinvolved fields is very wide, from classrooms to enterprises, andall demand for appropriate support. In particular, informationtechnology can provide such support, but it is not a trivialtask. On one hand, collaborative systems may be complex,distributed, open, and dynamic applications; on the other hand,the human factor plays a very important role with respect toother application fields.Collaboration is, for its own nature, distributed. Collaborationsupport systems must accomplish such distribution byexploiting appropriate technologies and must meet users’ requirementswhile also evolving or adapting to the users’ needs.Collaboration between different organizations can be achievedby the openness of the systems, a feature that could lead toglobal collaboration.Technological advance in collaborative systems is limited.Human perception and feeling are perhaps more important forthese systems to gain wide acceptance. Users are asked tocollaborate in (possible slightly) different ways from usual collaborations,and social aspects must also be taken into accountwhen designing collaborative systems.
