FIELD: physics, computer engineering.SUBSTANCE: invention relates to a system and a method of moving a cursor in response to movement of a pointing device. The method of moving a cursor (16) comprises controlling movement of a cursor (16) in response to movement of a pointing device according to a defined transfer function, wherein the transfer function is such that when the cursor (16) hits the edge of the screen (12) and the movement of the pointing device continues further beyond this point in a direction which cannot be followed by the cursor (16), the movement of the pointing device is remembered and the cursor (16) starts moving away from the edge again, when the pointing device (20) is moved back by the same distance as it was moved beyond the point when the cursor (16) hit the edge of the screen (12).EFFECT: providing improved cursor controllability on a screen due to a fixed relation between the position of the pointing device and the position of the cursor.14 cl, 4 dwg |
