  • Patent number: 8269733
    Abstract: An improved input precision touch panel having a sensor for detecting external pressure exerted on a display. The display displays an object icon, first auxiliary icon that corresponds to a detection area on which the sensor detects the pressure. On the display, the size of the first auxiliary icon is greater than the object icon and a second auxiliary icon corresponds to a second detection area, with the size of the second auxiliary icon greater than that of the object icon. Upon detection of external pressure an operation signal output unit outputs different operation signals according to positional relationships of a pressure-detected position on which the sensor detected the external pressure, in correspondence to a display position of the first auxiliary icon and a display position of the second auxiliary icon displayed by the display unit.
