ABSTRACT:
A pointer or mouse device which can provide an input for a viewpoint or cursor on a computer display without being physically moved across a surface or through space is disclosed. The pointer is mounted on a pedestal which is fixed. The pointer can rotate to change the direction in which it is pointing while on the pedestal. An extended movement button on the pointer provides a control signal to the computer to cause the viewpoint or cursor on the screen to move in the direction indicated by the direction the pointer is pointed at that time. Thus, the viewpoint or cursor can be moved without physically moving the pointer device. Instead, the pointer is simply rotated to the direction desired for movement and the extended movement button is pressed. A continue button may also be included to cause the viewpoint or cursor to continue rotating in the same way as when the button was pushed, without the user having to continue turning the pointer.
