A camera includes an image sensor, a signal processor, and an output unit. The image sensor obtains a first image being a subject image including an eye of a user of a head-up display. The signal processor generates a second image by reducing a resolution of an area of the first image other than an eyebox area. The eyebox area is an area within which a virtual image displayable by the head-up display is viewable by the eye of the user. The output unit outputs the second image to the head-up display.

A head mountable display apparatus includes a display unit to display one or more images to a user wearing the HMD, a first optical element and a second optical element each configured to direct light from the one or more images displayed by the display unit for viewing by a respective eye of the user, a first input unit to receive user information for the user indicative of a separation of the user's eyes, a second input unit to receive a user input, and an adjustment unit to adjust a current separation of the first and second optical elements responsive to the user input, where the display unit is configured to display a first image comprising one or more indicators indicative of the current separation of the first and second optical elements with respect to the separation of the user's eyes.

An augmented-reality-providing device includes a right eye lens having a first surface, a left eye lens having a first surface, a right eye filter overlapping the first surface of the right eye lens, and configured to change an illuminance of light passing through the right eye lens, a left eye filter overlapping the first surface of the left eye lens, and configured to change an illuminance of light passing through the left eye lens, a display unit configured to provide a first image to the right eye lens, and configured to provide a second image to the left eye lens, a right eye driver configured to control a transmittance of the right eye filter, and configured to control a transmittance of the first image, and a left eye driver configured to control a transmittance of the left eye filter, and configured to control a transmittance of the second image.

A three-dimensional display device includes a display panel that displays a parallax image, an optical panel including a plurality of less-transmissive portions and a plurality of transmissive portions repeatedly arranged alternately in a parallax direction, and a controller that controls the display panel. Each of the plurality of transmissive portions has a first width in the parallax direction greater than a second width of each of the plurality of less-transmissive portions in the parallax direction. The controller causes the display panel to display a black image in a binocular viewable area on the display panel viewable to two eyes of a user to allow parallax separation of the parallax image.

An apparatus that supplies multi-plane images for viewing by a user includes an image generator, an image director, and a first output port. The image generator generates a first image to be seen by the user as being a first distance from a user point of view, and a second image to be seen by the user as being a second distance from the user point of view The first image is comprised of a number of optical wavelength components, and the second image is comprised of the number of optical wavelength components. The image director is configured to direct the first image to traverse a first optical path to the first output port of the apparatus, and to direct the second image to traverse a second optical path to the first output port of the apparatus. The first optical path corresponds to the first distance and the second optical path corresponds to the second distance. The first optical path and the second optical path have different lengths. The first output port is configured to connect to a first optical waveguide that is configured to guide the number of optical wavelength components to a user display device.

Provided is a display apparatus including an image generator configured to time-sequentially generate a plurality of images by modulating light, and an optical system including a freeform surface that is configured to time-sequentially form a plurality of virtual images respectively corresponding to the plurality of images at different depths from a user's eye, wherein each error value among error values between the plurality of images and the plurality of virtual images respectively corresponding to the plurality of images on the freeform surface is less than or equal to a profile value of the freeform surface.

The invention relates generally to a user interaction system having a head unit for a user to wear and a totem that the user holds in their hand and determines the location of a virtual object that is seen by the user. A fusion routine generates a fused location of the totem in a world frame based on a combination of an EM wave and a totem IMU data. The fused pose may drift over time due to the sensor's model mismatch. An unfused pose determination modeler routinely establishes an unfused pose of the totem relative to the world frame. A drift is declared when a difference between the fused pose and the unfused pose is more than a predetermined maximum distance.

An autostereoscopic head-up display device includes two directional backlit type displays, a first reflector, a second reflector, a third reflector and a beam splitter. The two displays emit two image light beams with directivity, respectively, and the two image light beams are parallax image light for a viewer's eyes. One of the two displays, the first reflector, the beam splitter, the windshield and one of the viewer's eyes form a first light path, and the other one of the two displays, the second reflector, the beam splitter, the third reflector, the windshield and the other one of the viewer's eyes form a second light path. The two image light beams are projected onto the viewer's eyes through the first and second light paths, to form a stereoscopic image.

Configurations are disclosed for presenting virtual reality and augmented reality experiences to users. The system may comprise an image capturing device to capture one or more images, the one or more images corresponding to a field of the view of a user of a head-mounted augmented reality device, and a processor communicatively coupled to the image capturing device to extract a set of map points from the set of images, to identify a set of sparse points and a set of dense points from the extracted set of map points, and to perform a normalization on the set of map points.

The technology relates to a motion sensory and imaging device capable of acquiring imaging information of the scene and providing at least a near real time pass-through of imaging information to a user. The sensory and imaging device can be used stand-alone or coupled to a wearable or portable device to create a wearable sensory system capable of presenting to the wearer the imaging information augmented with virtualized or created presentations of information.
