Abstract: Three-axis acceleration component data from an acceleration sensor is split into three stationary components and three movement components. The axial direction of movement is detected based on the movement component having the maximum value. A shake duration is detected based on a time period from when this maximum movement component exceeded a an upper limit value of a specific range until it once again reaches a value in the specific range after falling below a lower limit value, or on a time period from when the movement component fell below the lower threshold value until it once again reaches the specific range after exceeding the upper threshold value. The magnitude of movement is determined by comparing the shake duration to a certain period, or by comparing the vector integral value over the shake duration to a certain threshold value.
