Patent number: 7102541Abstract: A force feedback interface having isotonic and isometric control capability coupled to a host computer that displays a graphical environment such as a GUI. The interface includes a user manipulatable physical object movable in physical space, such as a mouse or puck. A sensor detects the object's movement and an actuator applies output force on the physical object. A mode selector selects isotonic and isometric control modes of the interface from an input device such as a physical button or from an interaction between graphical objects. Isotonic mode provides input to the host computer based on a position of the physical object and updates a position of a cursor, and force sensations can be applied to the physical object based on movement of the cursor. Isometric mode provides input to the host computer based on an input force applied by the user to the physical object, where the input force is determined from a sensed deviation of the physical object in space.Type: GrantFiled: October 20, 2003Date of Patent: September 5, 2006Assignee: Immersion CorporationInventor: Louis B.

Patent number: 6894678Abstract: A mouse interface device and method for providing enhanced cursor control and indexing 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 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. Assistive forces can alternatively be output to achieve the enhanced cursor control.Type: GrantFiled: August 21, 2001Date of Patent: May 17, 2005Assignee: Immersion CorporationInventors: Louis B.

Patent number: 6850222Abstract: A method and apparatus for interfacing the motion of an object with a digital processing system includes a sensor which has a sensing resolution and detects movement of the object along a degree of freedom. An amount of play less than the sesning resolution exists between the sensor and the object. A passive actuator is coupled to the mechanism to transmit a resistive force to the object along the degree of freedom. A play mechanism is coupled to the actuator to provide a desired amount of play between the actuator and the object along the degree of freedom. The desired amount of play is greater than the sensing resolution of the sensor so that the sensor can detect the desired play when the user moves the object, even when the actuator has locked the object into place. Such desired play can be torsion flex (compliance) or rotary backlash. The actuator and the sensor provide an electromechanical interface between the object and the digital processing system.Type: GrantFiled: June 26, 2000Date of Patent: February 1, 2005Assignee: Immersion CorporationInventor: Louis B.
