Geocollaboration

The geocollaboration prototype was built to investigate how small teams share spatial information. Designed to support FEMA-type roles in a distributed emergency managment planning task, the system supports dual map views - one of data held individually by the team member and a second shared map where the team can do planning. Some of the rationale behind this design was to make more salient to the user what information they had shared with the team, while reducing clutter on the shared map where planning is done. This introduced some novel features for working with dual maps, such as tools to move content between the role-based and team map, as well as dual pointers which could be seen on both maps so the user could determine where on both maps he or she was pointing at. Experimentally, we examined the design through a set of "hidden profile" (Stasser et al.) tasks. In laboratory studies the prototype appeared to allow better performance on a hidden profile task compared to a same-place paper-based version of the same task.
