dc.description.abstractTabletop computers are increasingly being used for complex scenarios, such as emergency response. In such scenarios, maintaining situation awareness of dynamic changes automated by the system is crucial for users to make optimal decisions. If the system does not provide collaborators with appropriate feedback, they can become confused and “out-of-the-loop” about the current system state, leading to non-optimal decisions or actions. To enhance situation awareness of dynamic changes occurring in the collaborative tabletop environment, we designed an interactive event timeline to enable exploration of historical system events. We conducted a user study to understand how various design alternatives of interactive event timelines impacted situation awareness in the context of a co-operative tabletop game. Our initial results showed that, on average, all groups scored high on their combined level of situation awareness, regardless of the given timeline designs. To better understand what role the timelines played for the groups, we conducted an in-depth video analysis. Participants used the timelines mostly for perceiving new changes by interacting with the detailed information. The high-level information was beneficial for projecting future system states. The information presented in the timeline was considered as the correct historical account and was used for negotiating participants’ knowledge of the changes. We also report on how other system components, in addition to the interactive timelines, were used for situation awareness maintenance. Finally, we discuss implications for designing interactive event timelines for co-located collaborative systems involving automated events.en
