Abstract
A method and apparatus for providing dynamic force sensations for use with a force feedback interface device. A force feedback interface device is connected to a host computer that implements a graphical environment. The host sends commands and command parameters to the interface device to initiate and characterize dynamic force sensations output on a user manipulatable object, such as a joystick. The interface device can include a local microprocessor for implementing force sensations by controlling actuators and reading sensors according to the host commands. A dynamic force routine can control the dynamic force sensations by implementing a simulated physical system including a simulated mass capable of motion independent of the user object. The physical system provides forces on the user object influenced by motion of both the user object and the simulated mass.
