Abstract
A rotational input device is to be operated, and includes a device body, a rotatable unit rotating in response to operation, a sensing unit detecting an amount of rotation of the rotatable unit to generate a detection signal, and a processing unit connected to the sensing unit. After receiving the detection signal, the processing unit calculates an angular acceleration of the rotatable unit based on the detection signal, and determines whether the angular acceleration is greater than a predetermined threshold. In the affirmative, the processing unit divides the amount of rotation by a preset amount of rotation to obtain a first output value, and generates an input signal based on a second output value that is determined based on the first output value.
