Abstract: A system determining an intended cursor location on the computer display screen and automatically repositions the cursor at the intended location. If the user selects a command that alters the contents of the display, such as opening a new window, the system analyzes the new screen display to determine whether there are user selectable options associated with the new screen display. The system determines if one of the user selectable options is a default option and automatically positions the cursor at the default option. If the new screen display is an application program, the system attempts to locate a user selectable option and repositions the cursor at the user selectable option. When the new window is closed, the system returns the cursor to the position it was at before the new window was opened. The system also predicts an intended location for a screen display that has not been altered, and automatically positions the cursor at the intended location.

Abstract: A routine allows a user to move a cursor in only mutually perpendicular, horizontal or vertical directions on a computer screen, despite erratic or wavy movement of a pointing device. The routine, once enabled, receives mouse movement signals produced when the user moves the pointing device, the mouse movement signals having x and y position components. The routine uses the greater of the change in the x and y components to initially move the cursor in either horizontal or vertical directions, respectively. The routine continues to move the cursor along the initially established direction, even if the change in mouse movement signals in the other perpendicular direction become greater during continued mouse movement. Only when the change in mouse movement signals in the perpendicular direction become much greater (e.g., ten times greater) will the routine switch to moving the cursor along the perpendicular direction.
