A pair of electronic eyeglasses includes an eyeglasses frame and an eyeglasses lens mounted within the eyeglasses frame. At least one femtoprojector is embedded within the eyeglasses lens. The femtoprojector includes an image source and an optical system that projects an image from the image source onto the retina of the wearer. The femtoprojector is small enough that is does not significantly interfere with the wearer's view through the eyeglasses lens.

An augmented reality system and method configured to automatically provide a user, such as a physician, with a real-time heads-up view of a patient's real-time medical status using an augmented reality headset. The system can automatically identify patients, pull up relevant medical records, obtain real-time biomedical sensor data from the patient, and display this to the user while, at the same time, allowing the user to directly view the patient through the headset's transparent lenses, and leaving the user's hands free to manipulate the patient or perform other functions. The system and method are particularly useful for intensive care units and other emergency medical situations where the user needs to get an almost instant understanding of the patient's status.

A device for a head's up display comprises a picture generating unit; a projector optics; and a combiner. The combiner comprises a substrate made of optically transparent material and micro-optical structures arranged in a discrete array. The picture generating unit is arranged to deliver a beam of light, containing an image, to the projector optics. The projector optics and the combiner are arranged to form a virtual image of the image by reflecting a portion of the beam from the micro-optical structures. In the reflection, for at least a part of the beam reflected from the micro-optical structure, the resulting reflection deviates from the hypothetical reflection from the extrapolated substrate surface.

A variety of femtoprojector optical systems are described. Each of them can be made small enough to fit in a contact lens using plastic injection molding, diamond turning, photolithography and etching, or other techniques. Most of the systems include a solid transparent substrate with a curved primary mirror formed on one face, a secondary mirror formed on the opposite face, and an annular exit aperture located axially between the two mirrors The designs use light blocking, light-redirecting, absorbing coatings or other types of baffle structures to reduce stray light.

A control method applied in a display device is provided. The display device includes an image generator and a screen. The image generator is directed to output an output image. The screen is directed to operate in a first operation mode or a second operation mode. The screen has a first light-transmittance in the first operation mode and has a second light-transmittance in the second operation mode. The first light-transmittance is different from the second light-transmittance. In response to the screen operating in the first operation mode or the second operation mode, the image generator outputs the output image onto the screen in a light-emitting period and stops outputting the output image onto the screen in a non-light-emitting period after the light-emitting period.

The invention relates to a method of manufacturing a screen comprising transparent portions and retroreflective portions distributed over all or part of the surface thereof.

An interior structure for a vehicle includes an instrument panel disposed below a windshield, an air conditioning duct provided inside the instrument panel, and a head-up display device having a housing structure and mounted to the instrument panel, the head-up display device being configured to project information on the windshield. The head-up display device has a heat dissipating portion on an outer peripheral face of the housing. The air conditioning duct has a facing portion that faces the heat dissipating portion so as to be able to exchange heat with the heat dissipating portion.

The present disclosure provides a heads up display, comprising: a projector, which is configured to project light to a preset region to form a projected image; an environment color acquisition device, which is configured to acquire an environment color of a background region corresponding to the preset region, wherein the background region is an external region observable through the preset region from an observer's position; and a controller, comprising a color control unit, the color control unit being configured to control a color of light projected by the projector according to the environment color, such that a color of the projected image and the environment color are distinguished from each other. Accordingly, the present disclosure further provides a heads up display method and a traveling apparatus. The present disclosure can enable a driver to always see displayed image clearly in various environments.

An optic for a head mounted display having a first concave surface, a convex surface, and a second concave surface. The first concave surface receives light incident to its surface and transmits the light. The convex surface reflects light. The second concave surface reflects the light transmitted by the first concave surface and transmits the light reflected by the convex surface so that the light reflected by the convex surface travels through the second concave surface and is emitted outwardly.

First and second head up displays are installed so an angle at which a first and second center line intersect is =+ and a distance PD between a first and second virtual emission point, is PD=L(ML(WD)/(HW))/W. The is =arctan(W/2L), the is an angle of view of first or second virtual emission point, the W is a length of an eye box in a width direction of a vehicle, the L is a distance from an eye point to a virtual image plane, the M is a distance from the eye point to a point where a virtual image cannot be seen, the D is an interval between both eyes, and the H is a length of the virtual image plane on which the virtual image is displayed, in the width direction of the vehicle.
