1. A method for displaying a virtual environment on a video display comprising the repeated steps of:

  • determining a visual orientation of said display with respect to said virtual environment and generating an orientation signal representing said visual orientation;

    generating an image of said visual environment for said visual orientation identified by said orientation signal, said generating requiring a finite delay time;

    detecting any change in said visual orientation which may have occurred between a time when said visual orientation was determined and said image was generated; and

    displaying said image on said display, said image being shifted on said display by an amount equivalent to said change, whereby the display of the virtual environment is more stable.
