摘要： PROBLEM TO BE SOLVED: To provide a display system that uses aspheric lenses, controls the distance at which a virtual image is projected from a user and minimizes the distortions of the virtual image.
SOLUTION: Aspheric lenses 20 and 22 and displays 24 and 26 are arranged on a support section 14, the lenses are substantially made parallel to the surfaces of the displays, and the central axes of the lenses are extended along the normal direction, with respect to the surfaces of the displays. In the system, the virtual image appears at a prescribed distance which is smaller than the distance to a point at infinity from the user. Thus, the aspheric lenses and displays are arranged on the support section at a certain prescribed angle, that focuses with respect to the axes of the eyes of the user, when the user looks straight toward the front. The lenses and the displays are located at places where the prescribed prescribed angle is focused, with respect to the user's eyes and the user's eyes are directed inside with a natural, certain prescribed angle for the user who looks at the object body at a certain prescribed distance that is smaller than the distance to the point at infinity.

摘要： PROBLEM TO BE SOLVED: To provide a head mounted display system having an optical element shaped to minimize distortion and astigmatism. SOLUTION: The head mounted display system (10) is shown having a single optical element (28). The single optical element (28) has three optical surfaces. An entrance surface (S1) receives a video image directly from a display (26). A reflective surface (S2) reflects the video image from the entrance surface to an exit surface (S3) wherein a user views the video image directly through the exit surface. The three optical surfaces are shaped to generate a virtual image that is magnified, appears at a distance from the user and is substantially free from distortion, astigmatism and chromatic aberrations. The optical element is adjustably mounted on a frame (12) on a head-up display system to accommodate users with different interpupillary distances and to vary the apparent distance between the user and a virtual image.

摘要： A speech recognition manager receives representations of one or more words from a speech decoding system (106) and interprets the received words based upon the current context state so as to provide extremely accurate, flexible, extendable and scalable speech recognition and interpretation. The speech recognition manager limits the number of words that the speech decoding system (106) can recognize in a given context state in order to increase the speed and accuracy of the speech recognition process. Whenever the context state changes, the manager loads a new list of words that can be recognized for the new context state into the speech decoding system (106) so that while the speed and accuracy of the speech recognition process is increased, the total grammatical structure recognized can be easily increased as well.

摘要： An optical system (10) is shown for use with an image source (12) to provide an enlarged virtual image with minimal geometric distortion. The optical system is suitable for generating a virtual image of text information in small font sizes, such as 8 point font or 10 point font, where the small font size text can be readily discerned. The optical system includes a prism (14) having positive power wherein the total power is distributed among the prism's optical surfaces in a balanced manner and wherein the power across each surface is balanced as well. The prism employs a combination of rotationally asymmetric aspheric surfaces (18, 20) and a rotationally symmetric aspheric reflector (22) so as to provide an extremely high quality virtual image across the entire width thereof, i.e. in the edge or peripheral portion of the image as well as in the central portion of the virtual image. The prism may be used alone or in combination with a thin corrector lens that not only corrects for subtle distortions but also protects the prism from contaminants.

摘要： A binocular head mounted display unit (10) utilizing a single display (28) and binocular optical system (30) is shown for projecting an enlarged image of displayed information in the direct line of the user's eyes, while maintaining the user's peripheral vision free from obstruction to allow the user to selectively focus on the virtual image or not. The binocular optical system (30) directs the user's eyes inward at an angle that is natural for a person viewing an object at a distance that is less than infinity. Further, the binocular optical system (30) automatically compensates for variations in the interpupillary distances of various users, wherein those variations may be as great as one inch. This head mounted display unit (10) is suitable for a variety of applications, including virtual reality applications, as well as a display for a compact portable computer.
