Display Factors Influencing Co-located Collaboration

Understanding how various system features, such as input devices and displays, impact teamwork can form a basis to compare different collaborative systems. This paper concentrates on factors of physical display technology that influence co-located collaboration. We present seven such display factors: orientation of display, arrangement of users at the display, size of display, proximity to the display, privacy of the display, superimposition of display space on the input space, and number of displays. To illustrate their impact on teamwork, we describe how the display factors influence the mechanics of collaboration identified by Gutwin and Greenberg (2).
