<p>PURPOSE:To perform cooperative operation and individual operation on each terminal device by setting a logical communication path between objective programs and assigning a virtual area where an output result should be arranged for each objective program. CONSTITUTION:Logical communication paths 545, 550, and 555 are set among objective programs 500, 515, and 530 to which virtual areas 505, 510, 520, 525, 535, and 540 for output data display are assigned, position information in a virtual area generated by an indication device is sent as position information in a corresponding virtual area of each objective program, and corresponding solid processing is performed in each virtual area. Each virtual area can be handled like a conventional image plane and a figure which serves as a cursor is drawn in the virtual area. Consequently, the cursor for the object program is obtained in addition to an original terminal cursor and the degree of freedom of configuration variation, etc., is increased.</p> |
