Abstract
When an instructor such as a finger moves along a flat surface of a touch-sensitive tablet, a touch-sensitive tablet generates an input signal indicative of information of points touched with the instructor on the flat surface. A frame is provided around the touch tablet with a predetermined gap measured from the edge thereof. A maximum moveable range of the instructor of the flat surface is defined by the frame. The predetermined gap is determined such that the instructor can touch the periphery of the flat surface even when the movement of the instructor is restricted by the frame.
