  • Patent number: 8970962
    Abstract: A wearable system is shown that presents one or more heads-up displays to the wearer. A data source provides information to an image generator that is sufficient to generate one or more display images, which are still or moving, characters or graphical displays. The output image from the image generator passes through a lens, reflects off a curved mirror, and passes back through the lens the other way. The image then passes through two lenses, between which an intermediate image exists. The image reflects off the “lens,” or visor, of the glasses and proceeds to the pupil of the wearer's eye. Alternative embodiments use a helmet visor, mirror, or other (at least partially) reflective surface for the final reflection.

  • Patent number: 8965152
    Abstract: A projection display 210 arranged to display an image to an observer 212 use waveguide techniques to generate a display defining a large exit pupil at the point of the observer 212 and a large field of view, while using a small image-providing light source device. The projection display 210 uses two parallel waveguides 214, 216 made from a light transmissive material. One waveguide 214 stretches the horizontal pupil of the final display and the other waveguide 216 stretches the vertical pupil of the final display and acts as a combiner through which the observer 212 views an outside world scene 220 and the image overlaid on the scene 220. In a color display, each primary color is transmitted within a separate channel R, G, B.

    Abstract: A multifunction optical element including an image generating module that generates an image, and couples the image into a multifunction glass that has a coupling in area and a coupling out area. The image produced is coupled into the multifunction glass via the coupling in area, guided in the multifunction glass to the coupling in area, and coupled out via the coupling out area, in such a way that the user can perceive the coupled out image superimposed on the surroundings when the holding device is placed on the head of the user. The coupling out area has a Fresnel structure which receives light from the coupling-in-area via a folded beam path and couples the image out of the multifunction optical element. The coupling out element has an imaging property.

    Abstract: The following invention relates to an improved lens apparatus for use in a head up display (HUD), particularly for providing HUD with a depth of field and more particularly with providing a secondary virtual image in a different colour so as to provide a warning message. The partially reflecting combiner has a first surface S1 located closest to a display, and a second surface S2, located furthest from the display, wherein the effective radius of curvature of surface S2>S1, so as to provide two non-coincident virtual images. The selection of antireflective coatings on the surfaces S2 and S1 allows the non-coincident virtual images to have different coloured virtual images.

  • Patent number: 8941559
    Abstract: An optical see-through head-mounted display device includes a see-through lens which combines an augmented reality image with light from a real-world scene, while an opacity filter is used to selectively block portions of the real-world scene so that the augmented reality image appears more distinctly. The opacity filter can be a see-through LCD panel, for instance, where each pixel of the LCD panel can be selectively controlled to be transmissive or opaque, based on a size, shape and position of the augmented reality image. Eye tracking can be used to adjust the position of the augmented reality image and the opaque pixels. Peripheral regions of the opacity filter, which are not behind the augmented reality image, can be activated to provide a peripheral cue or a representation of the augmented reality image. In another aspect, opaque pixels are provided at a time when an augmented reality image is not present.

    Abstract: An eyepiece includes a first end for receiving display light, an end reflector, and a viewing region including a partially reflective surface to redirect at least a portion of the display light out of an eye-ward side of the eyepiece along an emission path. The partially reflective surface is obliquely angled to cause the emission path to have a first oblique angle in a first dimension relative to a first normal vector of the eye-ward side. The end reflector is tilted to cause the emission path to have a second oblique angle in a second dimension relative to the first normal vector of the eye-ward side. The first and second dimensions are orthogonal to each other.

  • Publication number: 20140376099
    Abstract: An angle mirror with image injection has an angle-mirror body, a viewing-in end, a viewing-out end, panels arranged in front of the ends, upper and lower deflection mirrors and a display. The image of the display is visible in the viewing-in end. The angle mirror makes it unnecessary for an observer's eye to refocus during an image-source change, such that he can recognize both represented image information items at the same time. This is achieved by arranging the display in a vertical direction on the angle mirror, configuring the lower deflection mirror as a beam splitter, arranging a first mirror element behind it, and guiding a first beam path of the display via an injection lens arranged on the angle-mirror body and likewise via mirror elements arranged thereon such that the first beam path is superposed at the beam splitter by a second beam path through the viewing-out end.
