Pick-and-Drop: A Direct-manipulation Technique for Multiple-Computer Environments

Pick-and-Drop is an extended concept of the commonly used drag-and-drop. With this technique, a user picks up an object on one computer display with a stylus, then drop it on a (possibly different) computer display. For example, a user can select or create a text on one's own PDA and pick-and-drop it at the desired location on the whiteboard. From the implementation point of view, the data is transferred through the network, but from the user-interface point of view, this technique allows a user to pick up digital data as if it were a physical object.
