摘要:
A system controls acquisition of visual targets with a cursor in a visual display displaced on a screen. A coordinate system is provided which is associated with the screen. A pointer is also provided which is associated with the cursor and which comprises a plurality of points in the coordinate system which define a cursor hot spot. The pointer is moved within the coordinate system based on position information from a user input device. A target region is provided in the coordinate system. The target region corresponds to a visual target and is acquired when at least one of the points in the cursor hot spot coincides with the target region.
