<p><P>PROBLEM TO BE SOLVED: To provide an operation device for disabling any operation based on the tilt angle of the device, and for preventing the selection of any unintended instruction key when the device is obliquely placed on a table or the like, and when the device is put in a pocket or bag or the like, and for reducing power source consumption by reducing the load of a control part which controls the selection of an instruction key or the display of an operation screen. <P>SOLUTION: When a posture vector R to be input by a coordinate converting part 8 satisfies prescribed conditions, that is, when it is detected that the posture of an operation device 1 has not changed for a prescribed time according to the posture vector R, or when it is detected that the tilt angle of the operation device 1 is a prescribed angle or more, and that an operation key Kp has not been depressed for a prescribed time according to the posture vector R, any operation based on a posture signal to be output by a tilt angle detecting part 6 can be disabled by a cursor control part 13. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
