Abstract: Techniques for adjusting a separation distance between stimuli generated by a pair of rendering cameras to accommodate an IPD of a user who is viewing the stimuli are disclosed. The IPD of the user is determined. A first stimulus, which is generated by a first one of the rendering cameras, is accessed. A second stimulus, which is generated by a second one of the rendering cameras, is accessed. The separation distance between the first stimulus and the second stimulus is determined. The separation distance is then reduced, resulting in the separation distance being narrower than the user's IPD. The first and second stimuli are then displayed in accordance with the reduced separation distance.

Abstract: A display device (100) according to the present disclosure includes a calculation unit that calculates a displacement of a baseline serving as a reference of display processing on right and left display units (110) on the basis of information obtained from a plurality of cameras (60) installed in the vicinity of the right and left display units corresponding to a user's visual field, and a conversion unit that converts an image displayed on the display unit so as to correct the baseline displacement calculated by the calculation unit.

Abstract: Systems and methods for capturing and rendering light fields for head-mounted displays are disclosed. A mediated-reality visualization system includes a head-mounted display assembly comprising a frame configured to be mounted to a user's head and a display device coupled to the frame. An imaging assembly separate and spaced apart from the head-mounted display assembly is configured to capture light-field data. A computing device in communication with the imaging assembly and the display device is configured to receive light-field data from the imaging assembly and render one or more virtual cameras. Images from the one or more virtual cameras are presented to a user via the display device.

Abstract: Methods, systems and apparatus for compensating vision loss for a patient. In some embodiments, a computer processor receives vision loss data associated with a vision loss region of an eye of a patient from a head mounted display (HMD) device worn by the patient, generates a parameterized perceptual loss model, and then generates inverse data to correct for color loss, contrast and luminance desaturation, and visual rotational and spatial distortion suffered by the eye of the patient. The computer processor then transmits the inverse data to the HMD device being worn by the patient for use in correcting the visual rotational and spatial distortion loss of the eye of the patient.

Abstract: The present disclosure generally relates to methods and interfaces for capturing and viewing immersive media. In some examples, in response to a hardware input, immersive media is captured and generated using multiple sensors of a head-mounted display device. In some examples, while displaying a media item, additional information related to the media item is displayed in response to detecting a viewer's attention departing from the media item.

Abstract: A display apparatus that includes an image display element, a collimating optical system that collimates light emitted from the image display element, a light guide plate on which light emitted from the collimating optical system is incident and that totally reflects and guides the light being incident, a first optical element that is disposed on the light guide plate and introduces the light being incident into the light guide plate, and multiple second optical elements that are disposed on the light guide plate and emit light propagated by total reflection in the light guide plate to outside of the light guide plate. The display apparatus is capable of suppressing generation of light (unnecessary light) other than light (image display light) to a wearer and suppressing manufacturing costs of the display apparatus.

Abstract: A display method, an electronic device, and a system for correcting display of images on a head-mounted display device are described. In a method, an electronic device may obtain an inter-pupillary distance (IPD) of a user based on user operations entered by the user based on user interfaces displayed on a head-mounted display device, correct a source image based on the IPD of the user to obtain target images used to be displayed on the head-mounted display device, and send the target images to the head-mounted display device. In this way, the user can comfortably and truly experience a 3D scenario when wearing the head-mounted display device.
