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.
