Information management strategies using a spatial-temporal activity structure

ABSTRACT

This paper briefly describes our temporally threaded workspace model, and provides experimental results on its effects on users' information management strategies. The model provides users with a workspace to gather, create, and organize information necessary for each of their activities. It records a series of workspace snapshots to represent the progress of an activity. Through experiments we observed that the snapshot mechanism reduces the mental barrier associated with deleting information. This leads users to represent the current state of the task more clearly. Further, we observed a novel information management strategy, which uses the time dimension, in addition to spatial dimensions.
