          Application 08/364,718                                                      


          lines 23-26.  Lewis teaches a high resolution vision system in              
          which remotely located sensors controlled by head and eye                   
          tracking means generate signals that are transmitted to signal              
          processing means on the helmet to produce a display image                   
          having a wide field of view that is maintained on the                       
          operator's line of sight.  See Lewis, column 1, lines 10-13.                
          Beckman teaches a virtual reality flight control system having              
          six degrees of freedom of acceleration or velocity control.                 
          Beckman, column 4, lines 30-35.                                             
               However, we find no objective teaching in either Lewis or              
          Beckman that would lead one of ordinary skill in the art to                 
          combine the references.  Lewis relates to the sensing of                    
          images outside an actual aircraft and addresses the problem of              
          remotely sensing and displaying images within a pilot's focus.              
          Consequently, Lewis' reference system merely involves the                   
          pilot's line-of-sight (LOS).  Beckman involves a virtual                    
          reality flight control system and addresses the problem of                  
          flight simulation in outer space.  Therefore, Beckman uses six              
          degrees of freedom in a more complicated reference coordinate               
          system that permits greater combinations of translations and                
          rotations.  Beckman and Lewis are directed to disparate
