ABSTRACT:
The movement of a manual input device in an information processing system determines the movement of a cursor across the system's display. The display visualizes a virtual space, e.g., in a multi-media environment. Certain stationary or moving areas on the display represent target areas serving as possible destinations for the cursor. In order to create a catching effect on the cursor, the system requires more user movement to leave than to enter the target region, thus enhancing target acquisition performance of the user.
