Abstract
An operating device for controlling electronic devices that are controlled by displaying plural operation keys on a touch panel is shown. The operating device stores the correspondence of a key code with an area on the touch panel, and outputs the key code corresponding to the area including a designated point. When there is a key that invalidates an operation input to the key, the operating device expands the areas of the keys adjacent thereto. Even if a user presses a border area between a desired key and its adjacent key, the operating device will judge that the desired key has been pressed.
