SOLUTION: A remote place device 3 transmits the video of a photographed document 5 for the remote place to an instruction device 1 via a network 2, and the instruction device 1 displays the video. When the prescribed position of a displayed document 5A is instructed by a cursor in the instruction device 1, the instruction device 1 calculates a control signal to deflect a laser beam 4 from the position to a position in the real document 5, and transmits the control signal to the remote place device 3 via the network 2. The remote place device 3 controls the direction of the laser beam 4 according to the control signal, and indicates a corresponding position on the document 5 with the laser beam 4.</p> |
