Method and apparatus for displaying speech information
First Claim
1. A wearable display system for producing a virtual image for viewing by a person comprising:
- a pair of spectacles adapted to be worn by the person and having at least one lens;
a transparent plate which supports and subtends said lens;
at least one lamp array mounted paraxially with the viewer'"'"'s line of sight on said plate for producing one of a plurality of images each indicating a group of speech sounds and projecting said one image forward of the viewer; and
at least one light transmitting mirror mounted adjacent said lamp array on said lens for reflecting said one image back to the viewer.

Abstract
A device for producing images of a plurality of speech information symbols associated with speech sounds produced by a speaker into the field of view of a hearing-impaired person with one or more light emitting or illuminated arrays mounted paraxially with the viewer'"'"'s line of sight on a transparent plate which subtends and mounts an adjacent eyeglass lens. A mirror is mounted on the lens to produce a magnified image in the field of view and reflect the image back to the viewer. The interior surface of the lens may be coated to form the mirror or spherical dimples may be ground into the surface before coating and the coated dimples then filled with a material having substantially the same refractive index as the lens.

3. A wearable device for producing an image of a plurality of speech information symbols associated with speech sounds produced by a speaker in the field of view of a hearing impaired viewer of said speaker comprising:
-
display means including at least one lamp array for producing an image of said symbol; and light transmitting means including a lens, a transparent plate fixed to and supporting said lens so as to subtend said lens and mounting said display means on a surface thereof paraxially with the viewer'"'"'s line of sight, said lens having a spherical dimple and transparent material filling said dimple and having substantially the same index of refraction as said lens, said material defining a mirror facing said display means for reflecting said image back to the viewer, and frame means for mounting said lens and plate in front of the eye of said viewer so that said image is magnified by said mirror to appear in said field of view as a magnified image to aid said viewer in identifying speech sounds.
