Abstract
An interface device and method for providing indexing cursor control with force feedback. A force feedback interface device includes a manipulandum, such as a mouse, that is moveable in a device 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, where the cursor is controlled by motion of the manipulandum. A force can be output on the mouse based on interactions in the GUI. Indexing features allow control of the cursor when an offset between local and display frames exists, allow the user to reduce the offset, and reduce disconcerting collisions of the mouse with physical workspace limits. Some indexing features include rate control borders for the device workspace, allowing rate control of a cursor when the mouse gets close to a physical limit; and border scaling allowing acursor to always be moved to a screen edge.
