<p>The method involves determining of the contact pints of three fingers (2,3,4) which are placed on the surface of the screen. The center point of the contact surfaces of the fingers on the screen is determined for the definition of the contact points. An equilateral triangle is mounted with a base between the center points of the two adjacent contact points away from each other. The sides are arranged path-breaking and its intersection point in the tip of the triangle (1) defines the position of a cursor, which positioned pixel accurate on the surface of the screen across a digital object (5).</p> |
