Recently I’ve been involved in the Cultural Heritage Informatics Initiative field school as a teaching assistant. Part of this involves the creation of mobile and location based technology. The first major project taken on by the students involved collaboration with the Campus Archaeology field school to create a historical tour of campus using Gowalla. On the CHI website I have written up the results of this tour and there is also a link in case your are interested in taking the tour. My project involved laying a historical narrative over reality to create a playful historic environment.
