Abstract
Apparatus and methods for providing positional and attitude information to a computer. An input device of the present invention comprises a controller, a transducer, and a mouse. In a 6D mode of operation, three-dimensional positional information with three degrees of freedom is provided to the computer. Multiple switches use an impedance ladder to provide multiple signals over a control line from a movable input device for a cursor or viewpoint on a display.
