  • Publication number: 20110310045
    Abstract: An input indication corresponding to operation intended by a user in a touch pad can be conducted, and operability can be improved. A tip coordinate Y of a touch region is calculated by a tip coordinate calculation unit 21 and a center coordinate y of the touch region is calculated by a center coordinate calculation unit 22 on the basis of touch information associated with a touch pad 16 which is detected by a detection unit 17. A determination unit 23 determines whether or not there is a travel of the touch region, and the travel distance calculation unit 24 calculates a travel distance of a touch point with the use of the tip coordinate Y or the center coordinate y on the basis of the determination result. When the touch region travels, the travel distance is calculated by the tip coordinates, and when the stop time, the separating time, and the touch start time of the touch region, the travel distance is calculated according to the center coordinates.
