  • Patent number: 9298012
    Abstract: In embodiments of eyebox adjustment for interpupillary distance, a first optical lens receives light of an image at a projected orientation of the light, and deviates the light by a deviation angle from the projected orientation of the light. A second optical lens receives the deviated light of the image from the first optical lens at the deviation angle, and alters the deviated light back to the projected orientation of the light for viewing the image. Left and right eyeboxes align with respective left and right eyes that view the image, and a distance between the left and right eyeboxes approximately correlates to an interpupillary distance between the left and right eyes. The light of the image can be laterally shifted to increase or decrease the distance between the left and right eyeboxes.

    Abstract: In embodiments of a flexible display extendible assembly, an extendible assembly includes a slideable display guide integrated in a first housing part of an extendible electronic device. The extendible electronic device includes a flexible display that slide-engages into the first housing part of the extendible electronic device. The extendible assembly includes an extendible mechanism that is coupled in a second housing part of the extendible electronic device and to the slideable display guide. The first and second housing parts of the extendible electronic device slide-engage relative to each other. The extendible mechanism is implemented to extend as the first and second housing parts slide apart relative to each other, and also to retract as the first and second housing parts slide together relative to each other.

  • Patent number: 9274338
    Abstract: 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.

  • Patent number: 9223138
    Abstract: In embodiments of pixel opacity for augmented reality, a display lens system includes a first display panel that displays a virtual image generated to appear as part of an environment viewed through optical lenses. A second display panel displays an environment image of the environment as viewed through the optical lenses, and the environment image includes opaque pixels that form a black silhouette of the virtual image. The display lens system also includes a beam-splitter panel to transmit light of the environment image and reflect light of the virtual image to form a composite image that appears as the virtual image displayed over the opaque pixels of the environment image.

  • Patent number: 9223441
    Abstract: A system determines a position of one or more objects relative to a detection surface. An illumination source is located at a first fixed position relative to the detection surface, and configured to illuminate an adjacent coordinate space. Two or more single-pixel optical sensors are located at fixed positions relative to the detection surface such that each point of the illuminated coordinate space is within a field of view of at least two single-pixel optical sensors. Each single-pixel optical sensor detects illumination reflected off an object within the coordinate space, and outputs information useable to assess a time-of-flight of the detected reflected illumination. A controller assesses a radial distance between each single-pixel sensor and the object based at least in part on the time-of-flight of the detected reflected illumination, and determines a position of the object in the coordinate space based at least in part on the radial distances.

  • Patent number: 9172856
    Abstract: In embodiments of a folded imaging path camera, a device includes a camera lens module that focuses an image, which is received as reflected light. An image sensor captures the image from the reflected light that is directed at the image sensor. The device also includes one or more optics that fold the reflected light of the image along an imaging path directed through the camera lens module and directed at the image sensor. The imaging path directed through the camera lens module can be approximately perpendicular to an axis along which the reflected light of the image is received via an aperture in the device. Alternatively, the imaging path directed through the camera lens module is approximately parallel to the axis along which the reflected light of the image is received via the aperture in the device.

  • Patent number: 9151984
    Abstract: In embodiments of active reflective surfaces, an imaging structure includes a circuit control layer that controls pixel activation to emit light. A reflective layer of the imaging structure reflects input light from an illumination source. An active color conversion material that is formed on the reflective layer converts the input light to the emitted light. The active color conversion material can be implemented as a phosphorus material or quantum dot material that converts the input light to the emitted light, and in embodiments, the active color conversion material is laminated directly on the reflective layer.

  • Publication number: 20150279102
    Abstract: 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.

  • Patent number: 8998414
    Abstract: Technology is provided for an integrated eye tracking and display system for a see-through, near-eye, mixed reality display device. Image data and IR illumination for eye tracking are optically coupled into a respective see-through, planar waveguide positioned to be seen through by each eye in a respective display optical system of the display device. The respective planar waveguide comprises one or more wavelength selective filters positioned to be co-axial with an optical axis of the respective display optical system. The wavelength selective filters direct IR and visible illumination out of the planar waveguide in the direction of the respective eye and direct IR reflections, including reflections from the eye, into the planar waveguide. The reflections are optically coupled out of the waveguide to an IR sensor which generates eye tracking data based on the reflections.
