Touch screen input method and device

摘要

A touch panel is constructed by a display/sensor unit which is slightly larger than a display screen of an LCD and a sensor unit which is projected to the outside from one side, for example, from one side on the right. A finger of the user is touched to a selection item such as desired button, icon, or the like on the display/sensor unit and vertically moved on the sensor unit. A selection display constructed by a plurality of buttons is displayed along the side of the display screen by the LCD. A button beside the finger is highlighted. When the finger is released, the highlighted button is selected. If there are no buttons adjacent to the finger, the button is not highlighted. Even if the finger is released, the state is not changed. When finger is moved to the display/sensor unit, the selection display disappears.
