Abstract: A head-mounted device may have displays that provide images. Waveguides may be used in conveying the images to eye boxes. The waveguides may overlap lenses in a glasses frame or other head-mounted support structure. The waveguides and lenses may be transparent. This allows real-world objects to be viewed from the eye boxes. Infrared-light reflectors may overlap the lenses. Gaze tracking system light sources may supply infrared light that reflects from the infrared-light reflectors to the eye boxes to illuminate a user's eyes. Gaze tracking system cameras capture gaze tracking images of the eyes from the eye boxes to track the user's gaze. Fiducials associated with the infrared-light reflectors may be monitored using the gaze tracking system cameras. This allows components such as the gaze tracking system cameras to be calibrated.

Abstract: Digital content items may include additional content such as advertisements. Placement of the additional content may be based on a characteristic of the digital content item and/or a characteristic of a consumer of the digital content item. In one implementation, a level of interest is determined for multiple time points in a digital content item and an advertisement is located in the digital item based on the level of interest.

Abstract: Introduced herein are a variety of techniques for displaying virtual and augmented reality content to a user through head-mounted display (HMD). The techniques described herein can be used to improve the effectiveness of the HMD, as well as general experience and comfort of a user of the HMD. For example, a binocular HMD system could modify the overlap of digital content in real-time so that the two separate images can be viewed without visual discomfort. The HMD system could also present visual stabilizers to each eye allow the user to more easily visually align the two separate images when viewed together. Techniques such as these decrease the eye fatigue and strain experienced by the user when viewing virtual or augmented reality content on HMDs.

In an example method of use, a clinician positions a patient, initiates a focal adjustment, initiates a retinal imaging process, and the same or a different clinician views the image. In some embodiments, the imaging system is configured to analyze the image and identify detected physical attributes in the image relating to the diagnosis and treatment of diabetic retinopathy.

Abstract: A target presenting apparatus includes: a display for emitting a target light flux; a concave mirror for receiving the target light flux in such a manner as to displace the target light flux from an optical axis thereof; a housing for accommodating the concave mirror and the display therein; and an optical member, placed in the housing, for guiding the target light flux from the inside to the outside of the housing to present a target to an examinee.

Abstract: A method and an apparatus of tracking an eye gaze to determine where a gaze point of a user is located on a display unit of a device, based on a facial pose and a position of an iris center, are provided. The method includes detecting a facial feature in a captured initial image, three-dimensionally modeling the detected facial feature, tracking the three-dimensionally modeled facial feature in consecutively captured images, detecting an iris center in the consecutively captured images, acquiring an eye gaze vector based on the tracked three-dimensionally modeled facial feature and the detected iris center, and acquiring a gaze point on a display unit based on the eye gaze vector.

Abstract: Embodiments according to the present disclosure are directed to, for example, head mounted eyewear (e.g., similar in form to traditional eye glasses) that includes low light vision enhancing and/or additional vision enhancing capabilities (e.g., near-vision enhancing capabilities).

The one or more optical elements may place an output of the image generator(s) into a position that is visible to the wearer's eye.

Abstract: A printing apparatus for performing printing in an inkjet mode includes an inkjet head, and a controller. The controller controls the inkjet head such that the inkjet head performs printing on a medium in a multi-pass mode. In each printing pass performed on each position of the medium, the controller controls the inkjet head such that the inkjet head ejects ink drops onto pixels designated by a mask data item. In a case where the spatial frequencies of the arrangement of ink dots formed on the medium during a first printing pass of the printing passes are referred to as first frequencies, and the spatial frequencies of the arrangement of ink dots formed on the medium during a second printing pass later than the first printing pass are referred to as second frequencies, the first frequencies are frequencies lower than the second frequencies.

Abstract: A mobile device comprises a pupil information collecting module and a master control module, such that the pupil information collecting module may be used for collecting pupil characteristic information of a user. The master control module may receive the pupil characteristic information of the user when the user accesses a controlled unit, and may determine, on the basis of the pupil characteristic in formation of the user, if the user is allowed to access the controlled unit. The mobile device may use the pupil characteristic information of the user to perform identity verification.

Abstract: To overcome problems with vergence, a binocular head mounted display (HMD) is used in a simulator in which an out-the-window scene is displayed in real time on a screen arrangement. Imagery for the left and right eyes of the HMD is derived by generating a starting HMD image for a Cyclops viewpoint between the user's eves, and then rendering respective views for each eve from the position of the eye in a virtual 3D model of the screen arrangement, wherein the starting HMD image is frustum projected against the screen arrangement of the 3D model.

Abstract: [Object] To enable suitable automatic switching of shutter glasses when receiving a multiplexed stream including, in a time sharing manner, a first video stream in which 2-dimensional image data has been inserted and a second video stream in which 3-dimensional image data has been inserted, and performing image display. [Solution] Advance information obtained from a transport stream is inserted at the transmission side with leeway of time T as to the switching timing between the first video stream and the second video stream. Based on this advance information, a shutter mode switching command is transmitted from a shutter control unit to shutter glasses, at a timing earlier than shutter mode switching timing. Based on this shutter mode switching command, the shutter mode is switched at the shutter glasses in accordance with the switching timing from the 3-dimensional image display to the 2-dimensional image display.

Abstract: Provided are an apparatus for obtaining status information of a crystalline lens and equipment including the same. The apparatus generates a reference light and directs the reference light to be perpendicularly incident to the crystalline lens. At least one light receiving unit that is disposed beyond a visual field of the eyeball is configured to directly receive scattered lights generated when the reference light incident from the light source unit to the crystalline lens is scattered against the crystalline lens. The apparatus calculates thickness information of the crystalline lens using information about the scattered lights received by the at least one light receiving unit.

Abstract: A timing signal generation unit of a content playback device generates a shutter control signal requesting the opening or closing of a shutter of a lens among one or more lenses of a pair of shutter glasses worn by a user viewing a display panel adapted to display content, and a backlight control signal requesting a backlight of the display panel to be turned on at least when the shutter is open. A transmitter unit transmits the shutter control signal to the shutter glasses. The timing signal generation unit changes at least one of the timing of turning on the backlight or the timing of opening the shutter of the lens of the shutter glasses.
