Head-up viewing display
First Claim

1. A field of view display by which a subject can view display data which is in focus on a far field of view comprising:
- (a) an optically transparent viewing medium interposed between a subject and the subject'"'"'s far field of view, said medium mechanically coupled to the subject'"'"'s head in order that movement of the head produces corresponding movement of said medium;
(b) electrically controllable display means attached to said medium in the field view of said subject for transmitting information to the subject, said display means occupying a relatively small angular area of said medium for permitting substantially unobstructed viewing of the far field of view; and
(c) focusing means connected to the medium between the subject and said display means, said focusing means operative to bring the display means into focus to the subject so that information transmitted by the display means is superimposed in focus on the subject'"'"'s field of view.

Abstract
A field of view display for presenting data in focus on a subject'"'"'s far field of view is disclosed. The display comprises an optically transparent viewing medium interposed between a subject and the subject'"'"'s far field of view. Display units are attached to or embedded in the medium for producing a visual signal to the subject which is small enough to allow substantially unobstructed viewing of the far field view. Focusing material connected to or comprising part of the medium between the subject and the display units brings the display units into focus on the subject'"'"'s field of view.

7. A field of view display for displaying data in focus on a subject'"'"'s distant field of view comprising:
-
(a) an optically transparent medium mechanically coupled to the subject'"'"'s head and interposed between the subject and the subject'"'"'s distant field of view; (b) electrically controllable display means attached to said medium in the field of view of the subject for producing a visual signal to the subject, said display means being small enough to allow substantially unobstructed viewing of the far field of view; and (c) focusing means optically coupled to the medium and positioned between the subject and the display means, said transmission means being operative to bring the display means into focus at a more distant plane than the physical plane of the display means. - View Dependent Claims (8, 9, 10, 11, 12)

13. A method for supplying information to a subject'"'"'s field of view comprising the steps of:
-
(a) interposing a transparent medium between the subject and the field of view and mechanically coupling the medium to the subject'"'"'s head; (b) optically coupling one or more convex lenses to the transparent medium, the solid viewing angle subtended by said lenses being small enough to insubstantially interfere with the subject'"'"'s viewing; and (c) causing the light rays from an electrically controllable information conveying means located in the field of view of the subject and attached to said medium to pass through said convex lenses in such a way that the information conveying means appears in focus at a more distant plane than the actual physical plane of the information conveying means. - View Dependent Claims (14, 15)
