Title: Computer system utilizing graphical user interface with hysteresis to inhibit accidental selection of a region due to unintended cursor motion and method

Abstract: A computer system, medium and method is disclosed for controlling selection and deselection of selectable regions on a computer display screen by a cursor, in such a manner as to compensate for the effects of jitter in the cursor control device. The system, medium, and method utilize a hysteresis technique, to accomplish their objectives. In a system with hysteresis it takes more force to effect a state change than would normally be the case; a state is harder to enter than it would otherwise be, and a state, once entered, is harder to leave than it would otherwise be. Such a state system with hysteresis is implemented in the present invention by having two thresholds for a state transition; one applied when moving into the state and the other applied when moving out of the state
