ABSTRACT
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.

Untangling the Concept of Task in Information Seeking and Retrieval
ICTIR '21: Proceedings of the 2021 ACM SIGIR International Conference on Theory of Information RetrievalMany researchers have pointed to tasks as being the driving force for Information Seeking and Retrieval (ISR). Unfortunately, researchers do not agree on what is meant by tasks and related concepts such as activities and search tasks. Researchers often ...
The Role of the Task Topic in Web Search of Different Task Types
CHIIR '18: Proceedings of the 2018 Conference on Human Information Interaction & RetrievalWhen users are looking for information on the Web, they show different behavior for different task types, e.g., for fact finding vs. information gathering tasks. For example, related work in this area has investigated how this behavior can be measured ...
