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.
Claims8
An information processing system comprising:
- a display for visualizing a virtual space;
- a manual input device coupled to the display and having a moveable part for enabling a user to guide a cursor through the virtual space in response to the user actuating the moveable part;
- wherein
- the system is operative to decrease an amount of movement of the moveable part, required to move the cursor a unit distance, below a pre-specified level when the cursor is within a target area in the virtual space and is moving towards a centre of the target area and to increase the amount above the level when the cursor is within the target area and is moving away from the centre.
A method of enabling a user to catch a target area with a cursor in a virtual space, visualized on a display, under control of a moveable part of a manual input device coupled to the display, the method comprising
- decreasing an amount of movement of the moveable part, required to move the cursor a unit distance, below a pre-specified level when the cursor is within a target area in the virtual space and is moving towards a centre of the target area;
- and
- increasing the amount above the level when the cursor is within the target area and is moving away from the centre.
