Hofte, Ingrid Mulder, Carla Verwijs] Use of presence and instant messaging (PIM) applications has grown very rapidly recently, not only at home, but also at work. Early studies on the use of PIM applications in the workplace, however, indicate that PIM applications need to be adapted towards the workplace context. In our research, we explore such adaptations, towards place-based presence systems, i.e., presence systems that are not only able to answer people-oriented presence queries such as "Who is online?” next to place-oriented presence queries, such as "Who is near?”. In this article, we describe a design space for place-based presence systems, in which we identify the most important aspects and options that designers of place-based presence systems need to consider. We also report on our exploratory research in this design space, comprising two cycles of designing, implementing and evaluating place-based presence prototypes. We conclude with lessons learned for future research in place-based presence systems.
