摘要:
Method and apparatus for providing peer-to-peer force feedback over a computer network. A network force feedback system includes a network, a first computer coupled to the network, and a second computer coupled to the network. The first and second computers each include a visual display and a force feedback interface device. Each computer provides a force feedback signal to its force feedback device based on information received from the other, remote computer and in some cases also based on input from the local force feedback device. Positional information of each force feedback device and/or feel sensation information can be transmitted between the computers over the network. A graphical environment can be displayed to enhance the interaction between users. The present invention therefore permits two computer users to interact using force feedback provided over a network on a peer-to-peer basis.

A digitizing system and rotary table for determining the three-dimensional geometry of an object. An apparatus includes at least one sensor detecting information describing the three-dimensional geometry of the object and providing the information to a host computer. A rotary table includes a base and a turntable rotatable about an axis positioned perpendicularly to the turntable surface. The turntable and object on its surface rotate about the axis during or between the sensor detecting the information describing the three-dimensional geometry of the object. A turntable sensor coupled to the base measures the rotation of the turntable, where the turntable sensor outputs turntable data indicative of the rotation to the host computer.

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.

摘要:
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. The position of the simulated object, as provided within the simulation and as displayed, is mapped directly to the physical position of the user object. This mapping is broken under conditions that are effective to provide force feedback to the user which imparts a physical sensation corresponding to the interaction of the simulated objects. In another aspect, a ball simulated ball object interacts with a user-controlled simulated object in a simulation to allow the user to utilize a wide range of physical skill and dexterity in interacting with the simulation. In another aspect, a simulation apparatus provides a display device such as one or more display screens or a projection device, and which also provides an intuitive mechanical interface device for the user to skillfully and dexterously manipulate objects within a computer-generated simulation.
