Abstract
An interface device and method for providing enhanced cursor control with force feedback. A force feedback interface device includes a manipulandum, such as a mouse, that is moveable in a local workspace. The device is coupled to a host computer that displays a cursor in a graphical environment, such as a GUI, on a display screen. A scaled cursor position in the display frame is reported to the host computer derived from a reference position of the mouse in the local frame, and the host displays the cursor. For example, the cursor position may be scaled by a ballistics algorithm based on mouse velocity to allow fine positioning or coarse motion of the cursor. A force is output on the mouse based on interactions in the GUI, the force being determined based on mouse reference data or cursor ballistic data, depending on the type of force, to reduce distortion between visual and force outputs.
