User Perception of Interaction Opportunities in Collaborative Human-Computer Settings AbstractTo investigate the interruption management problem empirically, we developed a new, abstract game using the Colored Trails (CT) infrastructure which has been used previously as a research test-bed for a variety of decision-making problems (Grosz et al. 2004). Our framework is abstract enough to enable us to focus on investigating the interruption problem without the specification overhead of real world domains. At the same time, it is sufficiently interesting for human participants to play that it provides a good environment in which to investigate human-computer interaction.
