摘要： 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.

摘要： 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. This feature can be selectively enabled to prevent the inadvertent repositioning of the cursor in the display.

摘要： A system for preventing inadvertent wrapping of a cursor generated on a computer display detects the location of the cursor in proximity with a border of the display and determines whether a user actually intends the cursor to wrap to the opposite side of the display. The system considers a variety of factors to determine whether the user actually intends to wrap the cursor. The time for which the user moves the cursor against the border, the distance that the cursor would have moved but for the border, and the velocity or acceleration with which the cursor approaches the border can all be considered by the system in determining whether or not to permit the wrapping of the cursor. The system automatically generates an indicator signal to permit the cursor to wrap from one side of the display to the opposite side. The user can select the size of the border and determine whether the border will have a color different from the normal display background color to visually indicate the location of the border to the user. The system can selectively enable and disable the border in response to a variety of factors. The user can manually generate the indicator signal by activating a command signal input. The system can operate in a graphical environment where a plurality of display windows are shown on the computer display. The system defines a border for each window to prevent the inadvertent wrapping of the cursor.
