“When new ideas and visions emerge from collective thinking and from a better understanding of current limitations related to technological achievements, the challenge remains as to ascertain how to put these ideas and visions into practice. That opens new research issues. My argument in this paper is that this principle is applicable also to the development of User Centered Design. UCD, of course, may contribute to the improvement, consolidation and verification of ideas and visions in the field. Yet, in order to be certain that UCD perspective is widely accepted and can properly influence the direction followed by technology and service development, we should be able to demonstrate that the approach will be useful and that it can be successfully implemented in relevant projects.” (Michele Visciola – ACM Ubiquity)
