  • B. Y. -L. Chang, S. D. Scott, and M. Hancock, Improving Awareness of Automated Actions using an Interactive Event Timeline, in Proc. ITS, 2013, pp. 353-356.

    Digital tabletops provide an opportunity for automating complex tasks in collaborative domains involving planning and decision-making, such as strategic simulation in command and control. However, when automation leads to modification of the system’s state, users may fail to understand how or why the state has changed, resulting in lower situation awareness and incorrect or suboptimal decisions. We present the design of an interactive event timeline that aims to improve situation awareness in tabletop systems that use automation. Our timeline enables exploration and analysis of automated system actions in a collaborative environment. We discuss two factors in the design of the timeline: the ownership of the timeline in multi-user situations and the location of the detailed visual feedback resulting from interaction with the timeline. We use a collaborative digital tabletop board game to illustrate this design concept.

    Overview+Detail interfaces can be used to examine the details of complex data while retaining the datas overall context. Dynamic data introduce challenges for these interfaces, however, as moving objects may exit the detail view, as well as a persons field of view if they are working at a large interactive surface. To address this "off-view" problem, we propose a new information visualization technique, called Canyon. This technique attaches a small view of an off-view object, including some surrounding context, to the external boundary of the detail view. The area between the detail view and the region containing the off-view object is virtually "folded" to conserve space. A comparison study was conducted contrasting the benefits and limitations of Canyon to an established technique, called Wedge. Canyon was more accurate across a number of tasks, especially more complex tasks, and was comparably efficient.

    Digital tabletops present the opportunity to combine the social advantages of traditional tabletop games with the automation and streamlined gameplay of video games. However, it is unclear whether the addition of automation enhances or detracts from the game experience. A study was performed where groups played three versions of the cooperative board game Pandemic, with varying degrees of automation. The study revealed that while game automation can provide advantages to players, it can also negatively impact enjoyment, game state awareness, and flexibility in game play.
