A force feedback and interactive system is provided in the present
invention, wherein the force feedback and interactive system utilizes a
mechanism for detecting weight or center of gravity and reacted force
from an operator on a multi-axis motion platform, and a main controller
which is a kernel of data processing and motion simulating of the
multi-axis motion platform. Besides having complete mathematical
simulation model for calculating reaction force variation according to
the received operating command, force status and weight of the operator
and having algorithm for simulating the motion of multi-axis motion
platform so as to calculate the motion and instantaneous position of the
multi-axis motion platform in space, the system can also provide function
of force feedback for enhancing the virtual reality while being applied
in various Human-Machine Interaction simulating field.
