<p>PROBLEM TO BE SOLVED: To make a cursor shifting position on a display screen agree with the cursor operating direction of an operator without respect to a rotational shift in a display screen indicating device based on a direction instruction with a roll angle correction in an interactive system using a graphical user interface. SOLUTION: A remote control unit 10 is provided with an angle detection part 15. When the operator operates the remote control unit 10 so as to change its direction, an angular change of the remote control unit 10 is detected in three directions including an axial direction perpendicular to the display screen and crossing at right angles with each other, and the detection data are fed to a screen coordinate computing part 20. In the screen coordinate computing part 20, computing based on the three direction angular change measurement result is carried out, and a deviation of an indicated position on the display screen due to a rotational shift of the remote control unit 10 is corrected.</p> |
