20130250430 | INCREASING FIELD OF VIEW OF REFLECTIVE WAVEGUIDE - A near-eye display system includes an image former and a waveguide. The image former is configured to form a display image and to release the display image through a first exit pupil. The waveguide presents a back surface that faces the wearer's eye, and a front surface opposite the back surface. The waveguide is substantially transparent to external imagery received normal to the front surface, and is configured to receive the display image from the image former and to release the display image through a second exit pupil, which is larger than the first exit pupil. | 09-26-2013 |
20130250431 | TWO-DIMENSIONAL EXIT-PUPIL EXPANSION - A near-eye display system includes an image former and first and second series of mutually parallel beamsplitters. The image former is configured to form a display image and to release the display image through an exit pupil. The first series of mutually parallel beamsplitters is arranged to receive the display image from the image former. The second series of mutually parallel beamsplitters is arranged to receive the display image from the first series of beamsplitters, and to release the display image through an exit pupil longer and wider than that of the image former. The second series of beamsplitters has a different alignment and a different orientation than the first series of beamsplitters. | 09-26-2013 |
20140168735 | MULTIPLEXED HOLOGRAM TILING IN A WAVEGUIDE DISPLAY - Embodiments related near-eye display devices having angularly multiplexed holograms are disclosed. One disclosed embodiment provides a near-eye display device including an image source, a waveguide, and a controller. The waveguide is configured to propagate light received the image source to a user of the near-eye display device, and includes a holographic grating comprising a plurality of angularly multiplexed holograms. The controller is configured to control display of an image via the image source. | 06-19-2014 |
20140240842 | ALIGNMENT-INSENSITIVE IMAGE INPUT COUPLING - Various embodiments are disclosed herein that relate to coupling light into waveguides in a near-eye display device in a manner configured to be tolerant to misalignment of the waveguides with each other and/or other optics. For example, one disclosed embodiment provides a near-eye display device comprising one or more waveguides, wherein each waveguide comprises a light input coupling configured to receive light at a first side of the waveguide to couple the light into the waveguide, and a light output coupling configured to emit light from the waveguide at a second side of the waveguide, the second side of the waveguide being opposite the first side of the waveguide. | 08-28-2014 |
20140327970 | SPHERICAL INTERFACE FOR BINOCULAR DISPLAY - A binocular display includes a waveguide. A convex spherical mount has a fixed position relative to the waveguide. A light engine includes a concave spherical mount that adjustably mates with the convex spherical mount. | 11-06-2014 |
20140375542 | ADJUSTING A NEAR-EYE DISPLAY DEVICE - Embodiments are disclosed herein that relate to aligning a near-eye display of a near-eye display device with an eye of a user. For example, one disclosed embodiment provides, on a near-eye display device, a method comprising receiving an image of an eye from a camera via a reverse display optical path, detecting a location of the eye in the image, and determining a relative position of the eye with regard to a target viewing position of the near-eye display. The method further comprises determining an adjustment to make to the near-eye display device to align the location of the eye with the target viewing position. | 12-25-2014 |
20140375789 | EYE-TRACKING SYSTEM FOR HEAD-MOUNTED DISPLAY - Embodiments are disclosed for a see-through head-mounted display system. In one embodiment, the see-through head-mounted display system comprises a freeform prism, and a display device configured to emit display light through the freeform prism to an eye of a user. The see-through head-mounted display system may also comprise an imaging device having an entrance pupil positioned at a back focal plane of the freeform prism, the imaging device configured to receive gaze-detection light reflected from the eye and directed through the freeform prism. | 12-25-2014 |
20140375790 | EYE-TRACKING SYSTEM FOR HEAD-MOUNTED DISPLAY - Embodiments are disclosed for a see-through head-mounted display system. In one embodiment, the see-through head-mounted display system comprises a freeform prism, and a display device configured to emit display light through the freeform prism to an eye of a user. The see-through head-mounted display system may also comprise an imaging device having an entrance pupil positioned at a back focal plane of the freeform prism, the imaging device configured to receive gaze-detection light reflected from the eye and directed through the freeform prism. | 12-25-2014 |
20150035744 | NEAR-EYE OPTIC POSITIONING IN DISPLAY DEVICES - Embodiments are disclosed for adjusting alignment of a near-eye optic of a see-through head-mounted display system. In one embodiment, a method of detecting eye location for a head-mounted display system includes directing positioning light to an eye of a user and detecting the positioning light reflected from the eye of the user. The method further includes determining a distance between the eye and a near-eye optic of the head-mounted display system based on attributes of the detected positioning light, and providing feedback for adjusting the distance between the eye and the near-eye optic. | 02-05-2015 |
