The system further includes a display device coupled to the rendering device via at least one physical layer. The display device includes a pixel array and a display controller coupled to the pixel array. The display controller includes a scaling component to upscale the first peripheral region to generate a scaled first peripheral region and a blending component to blend the foveal region with the scaled first peripheral region to generate a second image.

Abstract: A display system includes a display panel having an input to receive pixel data, the pixel data comprising a plurality of pixel values, an array of pixels partitioned into a foveal region and at least one peripheral region, and an array controller to group pixels in the at least one peripheral region into subsets of at least two pixels and to control each subset using a corresponding single pixel value from the plurality of pixel values. The display system further may include a rendering system to foveally render a display image based on the locations of the foveal region and the at least one peripheral regions, wherein for each row of the display image having pixels within at least one of the peripheral region, a number of pixel values represented in the pixel data for the row is less than a number of pixels in the row.

Abstract: A display device, such as a head mounted device (HMD), displays a virtual scene. The display device includes a motion tracker for detecting rotation of the display device. The display device also includes a processor that is configured to selectively maintain or modify a position of an array of rendered pixels relative to the virtual scene in response to the detected motion. The processor is also configured to upsample the rendered pixels to generate values of display pixels for presentation by the display device. The processor is further configured to translate the values of the display pixels in a rendering plane of the display device based on the detected motion. The translated values of the display pixels can then be presented on a display of the display device.

Abstract: A display system includes a display device and a graphics processing unit (GPU) coupled via at least one physical layer. The display device includes a pixel array having a non-red-green-blue (non-RGB) pixel format. The GPU is configured to render an image in the non-RGB pixel format and provide the rendered image for transmission to the pixel array via the at least one physical layer.

Abstract: A display device includes a pixel array and a display controller. The pixel array has a non-red-green-blue (non-RGB) pixel format that includes at least first, second, and third color components, and wherein sub-pixels of the first color component are present at a first resolution and sub-pixels of each of the second and third color components are present at a second resolution lower than the first resolution. The display controller is configured to receive a first image in a an RGB pixel format in which sub-pixels of the first color component, sub-pixels of the second color component, and sub-pixels of the third color component each are present in the first image at the second resolution. The display controller further is configured to scale sub-pixels of the first color component in the first image from the second resolution to the first resolution to generate a second image having the non-RGB format.

Abstract: An optical system has an aperture through which virtual and real-world images are viewable along a viewing axis. The optical system may be incorporated into a head-mounted display (HMD). By modulating the length of the optical path along an optical axis within the optical system, the virtual image may appear to be at different distances away from the HMD wearer. The wearable computer of the HMD may be used to control the length of the optical path. The length of the optical path may be modulated using, for example, a piezoelectric actuator or stepper motor. By determining the distance to an object with respect to the HMD using a range-finder or autofocus camera, the virtual images may be controlled to appear at various distances and locations in relation to the target object and/or HMD wearer.

Abstract: An optical system has an aperture through which virtual and real-world images are viewable along a viewing axis. The optical system may be incorporated into a head-mounted display (HMD). By illuminating a viewing location with an infrared light source, an eye pupil may be illuminated. Infrared light is reflected from the viewing location and is collected with a proximal beam splitter. An image former is configured to reflect at least a portion of the visible light pattern generated by the display panel to form the virtual image and transmit at least a portion of the collected infrared light. The transmitted infrared light may be imaged by a camera. The HMD may use images from the camera to provide, for example, context-sensitive virtual images to a wearer.

Abstract: A power supply and interface circuit assembly is used with a portable media player (PMP) to relay signals between the PMP and a peripheral device(s), such as a head-mounted display. A power supply in or attached to the assembly provides power to the circuitry, the PMP, and the peripheral device. The assembly is able to manage the charging and discharging of power to the PMP and the peripheral device and to manage multi-media signals between the PMP and the peripheral device to provide a complete, mobile interface assembly.

Abstract: A compact, lightweight, head-mountable display device is provided for transmitting an image to a user's eye. The device includes a projection system including a display attached at one end to a head-mountable support fixture. An eyepiece assembly is attached to a second end of the support fixture. The support fixture maintains the projection system and the eyepiece assembly in alignment along an optical path through free space between the projection system and the eyepiece assembly, with the projection system disposed to transmit the image on the optical path and the eyepiece assembly disposed to receive the image from the projection system and to direct the image to the user's eye.
