This workshop takes place in Stockholm between 14 and 16th of March and launches the EIT ICT Labs Presence Lab at KTH, a disused reactor hall on campus (www.r1.kth.se). The first workday focuses the theoretical body of knowledge relating to shared mediated spaces, and what may be said to constitute "A conceptual toolbox for presence design" while the following days are devoted to prototyping in the Presence Lab.
