Pilot helmet mounted CIG display with eye coupled area of interest

Claim 2

A display system adaptable as a training device that has the capability of imaging a scene in motion which is responsive to the actions of a trainee and which substantially matches the visual acuity of the human eye with the resolution of the image such that level of detail is allocated by priority to the area of interest then being observed by the trainee, comprising a sight line tracker, display means at least partially within the visual field of view of said trainee for presenting an observable scene of image information coupled thereto, computing means coupled to said tracker for ascertaining the orientation of the trainee's line of sight with respect to said display means, and means coupled to said computing means for electronically generating and providing image information for said display means from stored data by correlating said ascertained line of sight to said scene and allocating image detail in a predetermined hierarchy of resolution about said area that is being observed by said trainee as determined by said ascertained line of sight, whereby said hierarchy of resolution progressively decreases about said line of sight.

Claim 3

The display system of claim 1, further comprising a head tracker coupled to said computing means which ascertains the trainee's field of view, and wherein said image generating and providing means further correlates said ascertained field of view to said scene and dedicates said generated and provided image information to said field of view.

Claim 4

The display system of claim 1, wherein said display means includes projection apparatus that is responsive to movement of the headgear worn by said trainee.

Claim 5

The display system of claim 3, wherein said projection apparatus has a projector mounted atop said headgear and fixedly aligned therewith.

Claim 6

The system of claim 4, wherein said display means further includes a domed reflective screen upon which said display is presented that substantially encompasses the trainee's available field of view.

Claim 7

The system of claim 1, wherein said image generating and providing means includes an image generating computer programmed to dynamically allocate the available edges on a priority basis to that portion of a preprogrammed scene which corresponds to the area of the display that correlates to the sight line of said trainee.

Claim 8

The system of claim 6, wherein said image generating computer is further programmed to allocate edges on a progressively decreasing priority basis radially from said that portion.

Claim 9

The system of claim 7, wherein said computing means is a flight computer programmed to digitally detail motion in a preselected sequence to said image generating computer for display on said domed screen by said display means.

Claim 10

Training apparatus comprising a simulator that displays a computer generated image having a plurality of concentric regions that are ranked by hierarchy with the innermost region having the highest ranking and each region radially removed therefrom ranked progressively lower, and means for correlating the ranking of each region with the portion of said image that is displayed therein and allocating display detail by region such that the portion of said image in the innermost region has more display detail and the other portions likewise have a level of display detail that corresponds to their respective ranking with the outermost region having the least display detail, and further comprising means correlated to said display which identifies an observer's area of visual interest of said display for positioning said innermost region to correspond with said area of visual interest, such that resolution in said display decreases radially from said area of interest.

Claim 11

Training apparatus comprising a simulator that displays a computer generated image having a plurality of concentric regions that are ranked by hierarchy with the innermost region having the highest ranking and each region radially removed therefrom ranked progressively lower, and means for correlating the ranking of each region with the portion of said image that is displayed therein and allocating display detail by region such that the portion of said image in the innermost region has more display detail and the other portions likewise have a level of display detail that corresponds to their respective ranking with the outermost region having the least display detail, and further comprising means correlated to said display which identifies an observer's area of visual interest of said display for positioning said innermost region to correspond with said area of visual interest, such that resolution in said display decreases radially from said area of interest.

Claim 12

The apparatus of claim 9, wherein said simulator further comprises means for rendering motion in said image and relocation of said concentric regions on said display such that image portions may move from one region to another and regions may be moved across the image, wherein display detail is automatically adjusted by said correlating and allocating means for portion by region.

Claim 13

A flight simulator for training aircraft operators, comprising: a simulated aircraft cockpit with simulated aircraft controls that are responsive to actuation by said operator; a display screen substantially encompassing the field of view of said operator occupying said cockpit; a head tracker that continuously measures the orientation of the operator's head; an eye tracker that continuously measures the operator's line of sight; a computer image generator; processing means coupled to said simulated aircraft controls, said head tracker and said eye tracker for computing instructions for said image generator in response to said actuation and said measurements of head orientation and line of sight corresponding to a preselected flight sequence; means associated with said image generator for presenting a visual display on said screen; and means associated with said image generator for automatically allocating image detail by area in a predetermined set of concentric regions that are centered around the line of sight of said operator, with the region that intersects the operator's line of sight allocated to have more image detail than the other region(s) to form a display that approximately matches the visual acuity of the observer.

Claim 14

A flight simulator for training aircraft operators, comprising: a simulated aircraft cockpit with simulated aircraft controls that are responsive to actuation by said operator; a display screen substantially encompassing the field of view of said operator occupying said cockpit; a head tracker that continuously measures the orientation of the operator's head; an eye tracker that continuously measures the operator's line of sight; a computer image generator; processing means coupled to said simulated aircraft controls, said head tracker and said eye tracker for computing instructions for said image generator in response to said actuation and said measurements of head orientation and line of sight corresponding to a preselected flight sequence; means associated with said image generator for presenting a visual display on said screen; and means associated with said image generator for automatically allocating image detail by area in a predetermined set of concentric regions that are centered around the line of sight of said operator, with the region that intersects the operator's line of sight allocated to have more image detail than the other region(s) to form a display that approximately matches the visual acuity of the observer.
