Shared-Screen Interaction: Engaging Groups in Map-Mediated Nonverbal Communication

Abstract. This chapter describes the design and development of an interactive video installation that allows participants to explore a map narrative, and engage in group interactions through a shared screen. For this purpose, several layers of cartographic information were employed in a computer application, which was programmed with motion-tracking libraries in the open source tool processing. The interactive video installation has been chosen as a medium to achieve the following aims: (1) The visualization of urban-conflict as an interactive map narrative, and (2) the encouragement of social encounters through a shared screen. The development process begins with the design of interaction between the system and the participants, as well as between the participants themselves. Then we map the interaction design concepts into multimedia and architectural design. Finally, we provide a discussion on the creative process and the collaboration between different disciplines, such as architecture, urban planning, cartography, computer engineering, and media studies.
