Recent HCI research shows strong interest in task management systems (eg [19, 27]) that
support the multi-tasked nature of information work [13]. These systems either require users
to manually create and maintain task representations or they depend on explicit user cues to
guide the creation and maintenance process. To access and use the task representations in
these systems, users must also specify their current task. This interaction overhead inhibits
the adoption of these systems. In this paper, we present a novel approach to task …
Recent HCI research shows strong interest in task management systems (e.g. [19, 27]) that support the multi-tasked nature of information work [13]. These systems either require users to manually create and maintain task representations or they depend on explicit user cues to guide the creation and maintenance process. To access and use the task representations in these systems, users must also specify their current task. This interaction overhead inhibits the adoption of these systems. In this paper, we present a novel approach to task management that automates the creation and maintenance of task representations. Our system supports the user by making commonly used information more "ready-at-hand" through an intuitive visualization of their task representations. Users can correct and organize their task representations by directly manipulating the visualization; however, this interaction is not required. We describe a feasibility study that demonstrates the actual utility (in terms of overhead reduction) and perceived utility of our system.
