ABSTRACT:
An input device pointer remapping region on a computer display is disclosed. When the input device pointer enters a region on a computer display, such as a rectangular scroll bar region, the pointer advances by jumping to a point within the region, such as the center of the region. Further movements of the pointer through the region are adjusted to increase the likelihood that the pointer will remain in the region. However, these adjustments are performed in such a manner as to not impede the travel of the input device through the region. This allows the input device pointer to stay within regions when appropriate, yet allows it to pass through regions unimpeded when the user so desires. This allows for the more efficient use of valuable display space, and can even allow a scroll bar to fit within a narrow window border. The operation of the pointer within the region is controlled by a remapping factor. Selection of the remapping factor can be modified from region to region. In addition to rectangular regions such as scroll bars and window boundaries, square and circular regions are supported. Complex regions, made up of more than one other regions, are also supported.
