Abstract:
A pointing apparatus using a piezoelectric film, the apparatus comprising:a plurality of first strips arranged in a first direction at a first predetermined interval, each of which is extended in a second direction perpendicular to the first direction and at least some of the plurality of first strips is touched when a pointer is moved in the first direction; a plurality of second strips, which are lapped over the plurality of the first strips and arranged in the second direction at a second predetermined interval, each of which is extended in the first direction and at least some of the plurality of second strips is touched when the pointer is moved in the second direction, wherein each of the first and second strips generates electric charges in a quantity corresponding to pressure applied when a respective one of each of the first and second strips is touched and outputs touch signals having levels corresponding to the quantity of the electric charges; and a first direction detecting portion configured to detect a component of a moving direction of the pointer an order in which the touch signals are generated.
