Controlling acceleration of mouse cursor movement based on screen segments and image features

摘要

A method for controlling movements of a pointer through computer processing, where the pointer is displayed on a display device, includes the steps of: dividing a display area in which the pointer is movable into a predetermined number of regions, acquiring a current position of the pointer, determining in which of the divided regions the pointer is present (hereinafter referred to as a present region), computing a speed scale-factor for the pointer based on an image characteristic in the present region, and setting, as a moving speed in the present region, a normal moving speed of the pointer multiplied by the speed scale-factor.

1. A method comprising:
dividing a display area in which a pointer is movable into a predetermined number of regions, the pointer being displayed in the display area on an electronic display device through a computer process; acquiring a current position of the pointer within the display area; determining in which of the divided regions of the display area the pointer is present (hereinafter referred to as a present region); calculating, for each region, a speed scale-factor for the pointer based on an image characteristic of the portion of the image displayed within the region, wherein the image characteristic of the portion of the image presently displayed within a region is used in the calculation of the speed-scale factor for the region; and setting, as a moving speed in the present region, a normal moving speed of the pointer multiplied by the speed scale-factor of the present region, wherein the moving speed of the pointer for each region is the normal moving speed multiplied by the speed scale-factor.
