TOWER provides awareness of collaborative activities of team members and their shared working context through symbolic presentations in a Theatre of Work. The aim is to enhance distributed teams with group awareness and spontaneous communication capabilities close to those of co-located teams. TOWER supports group awareness and chance encounters through a 3D environment which is at the heart of the Theatre of Work. Users and their current actions on shared objects while using a groupware application are represented by avatars and their symbolic actions. Avatars of users who work in a similar context appear spatially close in the 3D environment. The integration of the Theatre of Work into a work setting opens new opportunities for spontaneous encounters and spontaneous contacts.
