1. An electronic apparatus, comprising:

  • circuitry configured to;

    detect an angular velocity of the electronic apparatus;

    contactlessly detect a relative velocity of the electronic apparatus in reference to a target object;

    detect a distance of the electronic apparatus to the target object; and

    compute an amount of movement of the electronic apparatus based on the angular velocity, the relative velocity, and the distance, without communicating with another object;

    the circuitry being further configured to;

    acquire a peak frequency of vibration generated at sliding of the electronic apparatus in reference to the target object based on the angular velocity;

    acquire a correction value based on the detected frequency; and

    compute a corrected velocity at the sliding based on the correction value and the angular velocity.
