Abstract.
GroupSketch allows a small geographically-distributed group to list, draw, and gesture simultaneously in a communal work surface, supporting interactions similar to those occurring in the face-to-face drawing process [4]. It is a simple group sketching tool that allows its users to draw on a virtual piece of paper (the screen). GroupSketch facilitates collaboration by:

• allowing gestural expression through large unique cursors visible on all displays;
• conveying the process of expressing ideas by transmitting small granular changes of user activity with minimum time delay;
• intermixing gestural, textual, and graphical expression modelessly; and
• providing simultaneous access to a common view of the work surface area, where any person can do any action at any time.
• The video illustrates several scenarios of GroupSketch in action.
