<p><P>PROBLEM TO BE SOLVED: To provide an operation device, capable of correcting a drift generated in output of an inclination sensor and detecting a correct inclination of the device. <P>SOLUTION: An attitude signal on design output from an inclination detection part 6 while the operation device 1 is mounted on a cradle is stored in a reference angle storage part 42 as a reference attitude signal. A coordinate conversion part 8 calculates, when an attitude signal outputted from the inclination detection part 6 is differed from the reference attitude signal with the operation device 1 being mounted on the cradle, a drift correction value for correcting the attitude signal output from the detection part 6 to the reference attitude signal in the reference angle storage part 42, corrects the attitude signal output from the detection part 6 with the drift correction value when the drift correction value is stored in the reference angle storage part 42, and calculates the inclination of the operation device 1 based on the corrected attitude signal. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
