Abstract
Methods, systems, and devices are described herein for providing an extended reality (XR) experience capable of both augmented reality (AR) and virtual reality (VR) functions. The XR device comprises transparent components enabling optical see-through (OST); the device comprising a transparent microLED display and a transparent image sensor together with a meta-lens. The XR OST device can switch between a fully immersive VR mode and an AR mode by controlling the display's transparency. Light from the exterior real-world scene is collected by the meta-lens on a wide field of view (FOV) and focused onto the transparent image sensor to detect objects in the real-world environment.
Claims19
An extended reality (XR) apparatus comprising:
- an opaque enclosure comprising a first face and a second face, wherein the first face and the second face are aligned along an axis;
- a meta-lens disposed in an opening of the first face of the opaque enclosure, wherein focal length of the meta-lens extends along the axis;
- a transparent light detector disposed, along the axis, between the meta-lens and the second face of the opaque enclosure, wherein the transparent light detector is disposed at a distance away from a back surface of the meta-lens, wherein the distance is based at least in part on the focal length of the meta-lens;
- a transparent display disposed, along the axis, between the transparent light detector and the second face of the opaque enclosure;
- an opening, along the axis, of the second face of the opaque enclosure;
- and
- a control circuitry configured to:
- analyze data produced by the transparent light detector based on light travelling through the meta-lens;
- and
- generate for display on the transparent display, at least one AR object, in a location based at least in part on analyzing the data produced by the transparent light detector.
An extended reality (XR) apparatus comprising:
- an opaque enclosure comprising a first face and a second face, wherein the first face and the second face are aligned along an axis;
- a meta-lens disposed in an opening of the first face of the opaque enclosure, wherein focal length of the meta-lens extends along the axis;

- a transparent display disposed, along the axis, between the transparent light detector and the second face of the opaque enclosure, wherein the transparent display further comprises a transparent liquid crystal display (LCD) screen disposed between the transparent display and the transparent light detector, wherein the LCD screen comprises at least two optical elements communicatively coupled to the LCD;
- and
- an opening, along the axis, of the second face of the opaque enclosure.
A method performed in a system that comprises:
- an opaque enclosure comprising a first face and a second face, wherein the first face and the second face are aligned along an axis;
- a meta-lens disposed in an opening of the first face of the opaque enclosure, wherein focal length of the meta-lens extends along the axis;
- a transparent light detector disposed, along the axis, between the meta-lens and the second face of the opaque enclosure, wherein the transparent light detector is disposed at a distance away from a back surface of the meta-lens, wherein the distance is based at least in part on the focal length of the meta-lens;
- a transparent display disposed, along the axis, between the transparent light detector and the second face of the opaque enclosure;
- and
- an opening, along the axis, of the second face of the opaque enclosure;
- the method comprising:
- analyzing, using a control circuitry, data produced by the transparent light detector based on light travelling through the meta-lens;
- and
- generating for display, using the control circuitry, on the transparent display, at least one AR object, in a location based at least in part on the analyzing the data produced by the transparent light detector.
