A system for providing realistic sensation within a simulation system by
providing tactile (haptic) feedback to a user. The system includes an
engageable practice tool that the user engages and a mechanical
simulation apparatus coupled to the practice tool. The mechanical
simulation apparatus includes a ground member, a mechanical linkage
rotatably coupled to the ground member, a linear axis member coupled to
the practice tool and the mechanical linkage, at least four actuators
coupled to the ground member, sensors for sensing movement of the
actuators, and at least three cables in contact with the at least four
actuators and coupled to the mechanical linkage. An interface device is
coupled to the simulation apparatus and a host computer is coupled to the
interface device for implementing an application program. The application
program provides signals for the actuators to move the cables and thereby
move the mechanical linkage.
