Abstract
In a collaborative system in which a body of shared data may be accessed by more than one user, a small-scale representation of the body of shared data displayed to one user includes an indication of the activities of other users. A user that is not viewing the shared data at full scale can thus obtain information about the activities of other users from a small-scale representation. The small-scale representation can indicate the type of activity, the extent or rate of changes in the shared data, the other users viewing the full-scale representation, or can show the shared data in shrunken form, indicating the parts that have been changed. The extent or rate of changes can be indicated with a quantitative indicator such as a gauge.
