Claim 6:
7. A system comprising:
a display device configured to display a dynamic virtual environment defined by an optical flow;
at least one position sensor device configured to obtain position data of an anatomical portion of a subject that is virtually traversing the dynamic virtual environment; and
a system controller device configured to use the position data to determine a mediolateral displacement measurement of the subject, utilize the mediolateral displacement measurement to define feedback control loop data, establish an augmented visual error that dynamically adjusts the dynamic virtual environment, wherein the augmented visual error is based on the feedback control loop data and a predefined visual gain factor, wherein the augmented visual error defines a difference between a virtual perception of trunk motion of the subject and an actual trunk motion of the subject, and adjust the optical flow of the dynamic virtual environment by using the augmented visual error.
