Document Type and Number:
Japanese Patent JP2623828
Kind Code:
B2
Abstract:
PURPOSE:To eliminate constraint to regulate usage only on a desk, etc., by the coordinate input of an instruction part by moving in all directions. CONSTITUTION:A coordinate instruction can be performed by directing a coordinate instruction part 101 having light emitting elements 401-403 to a coordinate point on the display picture plane of a display part 103, and moving it in a direction of targeted coordinate. The motion of the coordinate instruction part is detected at the light receiving element 409 of a light receiving part 102 installed in the neighborhood of the display part as the change of luminous intensity from the light emitting element. At the light receiving part 102, the angular change of the coordinate instruction part 101 can be obtained from the detected change of the luminous intensity, and it is sent to the display part 103, and at the display part 103, a display coordinate value is updated setting the angular change as the coordinate change of the display part 103, then, it is transferred to a new display coordinate. The coordinate instruction is completed when a displayed coordinate reaches the targeted coordinate, then, the input of the targeted coordinate is completed. Thereby, it is possible to eliminate the constraint to regulate the usage only on a specific place such as the desk, etc.
