The intended outcome in each case was to develop background documentation, feasibility studies, and a Roadmap of strategic directions.
The Moderators of Challenges GC2 and GC4 (involving different aspects of ubiquitous computing) agreed to combine them, and to add a new theme on human experience; the resulting Challenge GC2/4 had a new title.
A small committee for each Challenge was set up to carry it forward, together with an overall Steering Committee. Each Committee has elected a Chair.
