A method and apparatus for providing force feedback to a user operating a human / computer interface device in conjunction with a graphical user interface (GUI) displayed by a host computer system. A physical object, such as a joystick or a mouse, controls a graphical object, such as a cursor, within the GUI. The GUI allows the user to interface with operating system functions implemented by the computer system. A signal is output from the host computer to the interface device to apply a force sensation to the physical object using one or more actuators. This desired force sensation is associated with at least one of the graphical objects and operating system functions of the graphical user interface and is determined by a location of the cursor in the GUI with respect to targets that are associated with the graphical objects. The graphical objects include icons, windows, pull-down menus and menu items, scroll bars (“sliders”), and buttons. The force sensation assists the user to select a desired operating system function or physically informs the user of the graphical objects encountered by the cursor within the GUI. A microprocessor local to the interface apparatus and separate from the host computer can be used to control forces on the physical object.

A moving magnet actuator for providing haptic feedback. The actuator includes a grounded core member, a coil is wrapped around a central projection of the core member, and a magnet head positioned so as to provide a gap between the core member and the magnet head. The magnet head is moved in a degree of freedom based on an electromagnetic force caused by a current flowed through the coil. An elastic material, such as foam, is positioned in the gap between the magnet head and the core member, where the elastic material is compressed and sheared when the magnet head moves and substantially prevents movement of the magnet head past a range limit that is based on the compressibility and shear factor of the material. Flexible members can also be provided between the magnet head and the ground member, where the flexible members flex to allow the magnet head to move, provide a centering spring force to the magnet head, and limit the motion of the magnet head.

A sensor connecting sheet material for inclusion in appropriately structured multiple-axes controllers comprised of a single input member operable in 6 DOF relative to a reference member of the controller. The input member having return-to-center resiliency relative to the reference member on at least the three perpendicular linear axes. The input member can be of a continuously rotatable trackball-type or a limited rotation joystick-type, and the reference member can be a shaft, a base or a housing. The controllers include carriage structuring for influencing sheet connected sensors by hand-applied operation of the input member. The preferred structures provide cooperative interaction with movement or force influenced sensors in primarily a single area. Some, most, or all of the sensors are preferably supported on a generally single plane, such as on a printed flexible membrane sensor sheet or circuit board sheet. In an alternative embodiment, sensors and conductive traces are applied on a generally flat, flexible membrane sensor sheet, which is then bent into a three dimensional configuration which may in some cases reach a widely-spread 3-D constellation of 6 DOF and / or other sensor mountings. The use of sensors connected by a sheet member, whether finally applied in a flat or 3-D configuration, enables efficient circuit and sensor connection and placement during manufacture, resulting in low product costs and high reliability.

A method and apparatus for providing a click surface in a graphical environment, such as a graphical user interface, implemented on a host computer for use with a force feedback interface device. A displayed cursor is controlled by a user-moveable user object, such as a mouse, of the interface device. A click surface is displayed with an associated graphical object, such as a graphical button or an edge of a window, icon, or other object. When the click surface is contacted by the cursor, a force is output opposing movement of the user object in a direction into the click surface and into the graphical object. When the user object has moved to or past a trigger position past the contact with the click surface, a command gesture signal is provided to the host computer indicating that the graphical object has been selected as if a physical input device on the user object, such as a button, has been activated by the user. Preferably, the host computer displays the graphical environment including the click surface and cursor, while a microprocessor local to the interface device controls the force output of the click surface in parallel with the host display.

A method and apparatus for providing force feedback to a user operating a human / computer interface device and interacting with a computer-generated simulation. In one aspect, a computer-implemented method simulates the interaction of simulated objects displayed to a user who controls one of the simulated objects manipulating a physical object of an interface device.

A method and apparatus for providing low-cost, realistic force feedback including an improved actuator. The invention provides force sensations to a user and includes an interface device coupled to a host computer and allowing a user to interact with a host application program. A user object, such as a joystick, is moveable by a user in at least one rotary degree of freedom. A sensor reports a locative signal to the host computer to indicate a position of the user object. An actuator outputs forces on the user object in response to signals from the host computer and program. The actuator includes a housing, a set of grounded magnets provided on opposing surfaces of the housing and creating a magnetic field, and a rotor coupled to the user object positioned between the magnets. The rotor rotates about an axis of rotation and includes a shaft and teeth spaced around the shaft. An electric current flows through one or more coils on the teeth to cause the rotor to rotate. The teeth and the magnets are provided in a skewed, helical arrangement relative to each other so that, as the rotor rotates, a first tooth gradually exits the magnetic field as the next consecutive tooth gradually enters the magnetic field, thereby significantly reducing a cogging effect of the rotor when the user object is moved by the user and increasing the fidelity of forces experienced by the user.

A haptic feedback system comprises a moveable device with at least three degrees of freedom in an operating space. A display device is operative to present a dynamic virtual environment. A controller is operative to generate display signals to the display device for presentation of a dynamic virtual environment corresponding to the operating space, including an icon corresponding to the position of the moveable device in the virtual environment. An actuator of the haptic feedback system comprises a stator having an array of independently controllable electromagnet coils. By selectively energizing at least a subset of the electromagnetic coils, the stator generates a net magnetic force on the moveable device in the operating space. In certain exemplary embodiments the actuator has a controllably moveable stage positioning the stator in response to movement of the moveable device, resulting in a larger operating area. A detector of the system, optionally multiple sensors of different types, is operative to detect at least the position of the moveable device in the operating space and to generate corresponding detection signals to the controller. The controller receives and processes detection signals from the detection sensor and generates corresponding control signals to the actuator to control the net magnetic force on the moveable device.

A three-dimension image processing apparatus includes a CPU. When the CPU detects by collision determination that another object, e.g., a wall, is existent between an operable object and a camera, it calculates such a moving angle of the camera that an eye of the camera to the operable object is not obstructed by the other object. The camera is moved in accordance with the moving angle to a position where the operable object and the other object existing in a photographed three-dimensional space are displayed on a display.
