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 |
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 |
20150138160 | RETRACTABLE TOUCHSCREEN ADAPTER - An apparatus for determining a location of an object on a planar surface is provided. The apparatus includes a retractable emitter strip, a retractable detector strip, and electrical circuitry. The retractable emitter strip is extendable from the apparatus and includes electro-optical emitters for generating optical energy and directing the optical energy across a planar surface. The retractable detector strip is extendable from the apparatus and includes optical detectors for receiving other optical energy directed across the planar surface from another instance of the apparatus. The retractable emitter strip and the retractable detector strip extend in different directions from the apparatus. The electrical circuitry drives the electro-optical emitters to produce the optical energy according to a pre-defined pattern and processes electrical signals received from the optical detectors to generate object location information. The electrical circuitry also wirelessly transmits the object location information to a system controller. | 05-21-2015 |
20150220172 | WEARABLE COMPUTING SYSTEMS - Embodiments relate to wearable computing devices. For example, one embodiment provides a computing device comprising a body including a dorsal end configured to be located along a dorsal side of a wrist and a lateral end configured to be located along a lateral side of the wrist when the computing device is worn on a wrist. The body comprising a planar portion extending in a planar configuration from a dorsal end partially toward the lateral end, and a curved portion extending from the planar portion to the lateral end. The device further includes a display coupled to the body and extending along at least a portion of the planar portion and at least a portion of the curved portion of the body, and a securing structure configured to connect to the dorsal-side edge and the lateral-side edge and to extend around the wrist to secure the body to the wrist. | 08-06-2015 |
20150223355 | WEARABLE COMPUTING SYSTEMS - One embodiment provides a computing device comprising a computing device body, a display coupled with the computing device body, a first set of computing components incorporated into the computing device body, and a securing system configured to secure the body to a wrist, the securing system comprising a plurality of detachable modular segments joined together to form a second set of computing components that is modifiable by changing segments. Each modular segment comprises a first mechanical connector and a second mechanical connector, a first set of electrical connectors and a second set of electrical connectors, and one or more electrical components incorporated into the modular segment, such that a functionality of the computing device is modifiable by changing modular segments. | 08-06-2015 |
20150279102 | DISPLAY RELATIVE MOTION COMPENSATION - Embodiments that relate to displaying an image via a display device worn on a head of a user are disclosed. In one example embodiment, an image is displayed at an initial registration position with respect to a user's eye. Composite motion data is received from one or more sensors, with the composite motion data comprising a head motion component and a relative motion component which is relative motion between the head and the display device. The composite motion data is filtered to remove the head motion component and yield the relative motion component. Using the relative motion component, the initial registration position of the image is adjusted to an adjusted registration position that compensates for the relative motion component. The image is then displayed at the adjusted registration position. | 10-01-2015 |
