Enhanced cursor control using interface devices
First Claim
1. A method, comprisingdetermining a first region and a second region of a workspace;
- receiving a signal indicating a movement of a manipulandum in the workspace;
determining a first mapping associating the movement of the manipulandum with a first cursor movement within a graphical environment;
determining a second mapping associating the movement of the manipulandum with a second cursor movement within the graphical environment;
selecting one of the first mapping and the second mapping to be associated with the manipulandum crossing a boundary between the first region and the second region;
displaying a cursor in the graphical environment based at least in part on the selection of one of the first mapping and the second mapping; and
outputting a force effect to the manipulandum, the force effect associated with the movement of the manipulandum relative to a constrained range of motion of the manipulandum.

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. An interior region and a border region in the local workspace is defined. One mapping of device movement to cursor movement is used for the interior region, and a different mapping is used for the border region. Mapping methods include ballistics, absolute, linear, rate control, and variable absolute. Rate control embodiments can be single axis or dual axis. In one embodiment, when the mouse moves from the interior region to the border region, the mapping providing the greater cursor velocity is used to better conserve device workspace in the direction of travel and to decrease any sense of mapping mode change to the user. Other features include an autocentering function for reducing offset between local and host frames.
