Abstract
Since the surface of the touch panel is often slippery, pressure points of the writing stylus on a touch panel may easily skip along the input contiguous line. The present invention calculates the velocity of writing stylus movement at each segment of the input contiguous line from a touch location and detection time of each touch which may be detected at intervals, produces a line drawing which connects each pair of touch locations of touches that are temporally adjacent in the detection order with a line of a type determined based on the calculated velocity, and displays the line drawing on the LCD.
