A system and method for providing a tactile virtual reality to a user is present. The position and orientation of the user is utilized to generate a virtual reality force field. Forces are in turn generated on the user as a function of this force field. A six-axis manipulator is presented for providing a user interface to such a system. This manipulator provides a unique kinematic structure with two constant force springs which provide gravity compensation so that the manipulator effectively floats.

A method for providing tactile force feedback in response to a user position and orientation, the method comprising the steps of: storing data representative of a computer model, including one or more objects having surfaces; generating an electrical signal for each of a plurality of degrees of freedom of the user as a function of the user position and orientation; synthesizing user velocity and acceleration from the electrical signals to determine user-applied force; mapping the user position, orientation and applied force with respect to computer model to determine interactions between the user and any objects included in the model; generating at least one force field in response to the interactions; generating a force signal for each degree of freedom as a function of the force field; and directing a tactile force on the user for each force signal, the generated tactile forces providing the tactile feedback.
