Apparatus and method for controlling a screen pointer |
摘要 |
An apparatus for controlling a position of a screen pointer for an electronic device having a display screen includes a touchpad including a touch-sensitive surface on which a pointing object may be placed. The touchpad is configured to generate position signals indicative of positions of the pointing object on the touch-sensitive surface. The apparatus includes a controller for generating a first set of movement data based on the position signals. The first set of movement data is indicative of motion of the pointing object across the touch-sensitive surface. The controller is configured to generate a second set of movement data when the pointing object is removed from the touch-sensitive surface, thereby leaving the touch-sensitive surface free from contact by a pointing object. The second set of movement data is indicative of motion of the pointing object across the touch-sensitive surface prior to removal of the pointing object. |
