Abstract
Shared multitouch workspaces offer interpersonal exchanges similar to whiteboards and chalkboards, with additional benefits such as distributed collaboration and longitudinal data capture. This research investigated the space needed for single person use and prospective multi-person collaborative work on a mock multitouch screen system. Sixteen participants performed simulated movements of multitouch tasks across three screen angles (horizontal/vertical/self-adjusted) and two scenarios of use (single person/mock two-person collaboration). Basic space planning needs were analyzed across screen angles and scenarios of use. Preferred screen tilt angles are discussed and two fixed screen angles are suggested.
