PROBLEM TO BE SOLVED: To provide an operation device or the like for a correction factor of direction sensor and for appropriately computing a dynamic correction factor in consideration of the static installation angle of the direction sensor and its dynamic change in the installation angle when correction factors for correcting direction sensor information are to be computed based on GPS information and direction sensor information before and after of the direction change. SOLUTION: Basic correction factors of the direction sensor information are computed on the basis of the difference between the amount of the change in GPS direction and the amount of change in sensor direction before and after direction change. The static correction factors which are corrected using basic correction factors are computed according to the static installation angleαof a detection axis X of the direction sensor 4. According to the dynamic change angleβin the direction the detection axis X of the direction sensor 4, the dynamic correction factors are computed by correcting dynamically the static correction factors.
