1. A method of providing a virtual reality in response to a position and orientation of a member representative of a medical instrument, the method comprising the steps of:

  • providing a first medical instrument having sensors for position and pressure;

    performing an actual medical procedure using the first instrument;

    measuring and recording during the actual medical procedure data representative of the position and orientation of the first instrument and the pressures experienced by the first instrument;

    providing a member representative of the first medical instrument;

    generating an electrical signal for each of a plurality of degrees of freedom of the member as a function of the position and orientation of the member in three-dimensional space;

    generating at least one virtual reality force field in response to the generated electric signals as a function a the recorded position and pressures experienced by the first instrument;

    generating a force signal for each degree of freedom as a function of the force field; and

    directing a force on the member for each force signal, the generated forces providing the virtual reality.
