Method and apparatus for cursor movement control. |
摘要 |
<p>Apparatus for moving a cursor while constrained on a selected graphics object displayed on a display screen (4) comprises a mouse (6) or similar device for entering a signal for pointing to a position on the display screen (4); means (5) for determining a point on the display screen (4) in response to the signal entered by the mouse (6); means (1,2) for determining a point on the graphics object which is near the point determined by means (5); and means (3) for displaying the cursor at the point determined by means (1,2). Graphics objects can thus be tracked by means of a cursor without requiring the specification of points or directions prior to tracking thereby providing the user with direct control of the movement of a cursor constrained onto graphics object. <IMAGE></p> |
