A multifunctional virtual-reality fitness equipment provide user to select mode of one user doing exercise alone or multiple users participating in on-line internet competition game with others through internet, which has a detachable interactive
manipulator equipped with single-
chip microcontroller and served as an interface for
coupling conventional fitness equipment and
personal computer to enable the conventional fitness equipment to become a novel man-
machine interaction fitness equipment having function of internet 3-dimensional virtual
simulation, and the communication between the detachable interactive
manipulator and the
personal computer is achieved by employing male-to-female plug-socket connecting means and according the
International Standard Communication Protocol; when the detachable interactive
manipulator is connected to a
personal computer and a fitness equipment, an automatic detection to
software program of personal computer shall be executed, if correct message is detected, the fitness equipment will be set in 3-dimensional virtual
simulation mode capable of performing an internet 3-dimensional virtual
simulation function, and the user may select this mode to execute an on-line internet competition game with others through internet, however, if no
software program of personal computer was detected, the fitness equipment is still used as a conventional fitness equipment to provide user doing exercise alone.
