The system supports the following group activities. People can simultaneously manipulate the objects in either the radar or detailed view. People can point to objects in both the radar view and the detailed view. People can express ideas, for all fine-grained actions are visible as they happen. When participants are not looking at the same thing in the detailed view, they can see other people's actions in the radar view.
People can pursue individual as well as collaborative work.
If they want to work closely together, they can quickly align their view rectangle atop one another. People can maintain awareness of one another even when working on quite different parts of the concept map. The radar view shows other people's presence and location through both the view rectangles and the telepointers, and can see what others are doing because all actions are immediately visible. The detailed view also shows where another person's view overlaps with one's own by displaying the common region as a colored box. Of course, telepresence and teledata should work together.
