<p>This invention provides a touchscreen that, even when using an ordinary off-the-shelf general-purpose stylus, can detect the tilt of said stylus and can detect the coordinates of the tip of the stylus with a high degree of precision. Said touchscreen (3), which detects the coordinates of the tip of a stylus, is provided with the following: a touch-coordinate detection circuit (6) that detects the coordinates of the tip of the stylus and the coordinates of the hand supporting said stylus; and an input-means-tilt-angle computation unit (7) that computes the distance between the tip of the stylus and the hand on the basis of the coordinates of the tip of the stylus and the coordinates of the hand and computes the tilt angle of the stylus from said distance.</p> |
