Multi-dimensional, non-linked method and apparatus for producing a simulated feeling of force on a preselected location on a human operator in a synthesized environment accomplished by generating a first, constant, stationary electromagnetic field and a second, varying electromagnetic field local to the human operator. The variance of the second electromagnetic field is controlled by electrical currents which are responsive to parameters describing the position and orientation of said preselected location on the human operator and such variance results in attraction and repulsion of the first and second electromagnetic fields emulating a feeling of force on the human subject.
