Abstract: This document relates to head mounted display devices. One example can include a housing configured to be positioned relative to a head and eye of a user and a transparent visual assembly positioned by the housing in front of the user's eye and comprising multiple eye tracking illuminators distributed across the transparent visual assembly and configured to emit non-visible light and multiple eye tracking detectors distributed across the transparent visual assembly and configured to detect the non-visible light reflected back from the eye of the user.

Abstract: In various embodiments, a hand-held, desktop, boom, or mechanical arm-mounted apparatus including wide field-of-view (greater than 60-degrees measured diagonally) collimating optics and using either a stereoscopic or offset biocular assembly to remove parallax due to the position of the display can be configured to augment the display on a computer, laptop, tablet, or other image-generating device for the purposes of enhancing its immersive properties.

Abstract: A display device includes a waveguide, a reconfigurable phase mask, and a controller. The controller dynamically reconfigures the reconfigurable phase mask so as to modulate display light in accordance with a detected position of an eye and/or a parameter for a shape of the waveguide. The waveguide transmits the modulated display light.

Abstract: An apparatus for displaying an image to an observer. The apparatus comprises a display screen upon which stripes of the image appear in at least three distinct phases. The apparatus comprises a light blocking shutter disposed in front of the display screen forming a stripe pattern which lets through only ? of each stripe of the image on the display screen during each of the at least three distinct phases. The apparatus comprises a computer connected to the display screen and the light blocking shutter which changes the phases so in each phase the stripe pattern is shifted laterally, which renders 2 3D scenes corresponding to the eyes of the observer, which produces a proper left/right orientation pattern for each of the three phases and which interleaves the left/right orientations into three successive time phases as red, green and blue, respectively. The apparatus comprises an eye tracker for identifying the locations of the observers' eyes and providing the location to the computer.

Abstract: Apparent distance of a pixel within an optical field of view is determined. Incoming light is scanned along a raster pattern to direct light for a select pixel onto a light distance detector. The distance is sampled for each pixel or for a group of pixels. The light distance detector includes a concentric set of rings sensors. The larger the spot of light corresponding to the pixel, the more rings are impinged. The diameter of the spot is proportional to the distance at which the light originated (e.g., light source or object from which light was reflected). Alternatively, a variable focus lens (VFL) adjusts focal length for a given pixel to achieve a standard spot size. The distance at which the light originated correlates to the focal length of the VFL.

Abstract: An apparatus for viewing includes a screen. The apparatus includes means for detecting a fixation point of a viewer's eyes on an image on the screen. The apparatus includes means for displaying a foveal inset image on the image on the screen about the fixation point so a viewer's fovea sees the foveal image while the rest of the eye sees the image. A method for viewing. The method includes the steps of detecting a fixation point of a viewer's eyes on an image on a screen. There is the step of displaying a foveal inset image on the image on the screen about the fixation point so the viewers fovea sees the foveal image while the rest of the eye sees the image.

Abstract: A system for manipulation of objects. The system includes N objects, where N is greater than or equal to 2 and is an integer; and a mechanism for controlling and 2D locating of the N objects. A method for manipulating objects. The method includes the steps of receiving information from N objects, where N is greater than or equal to 2 and is an integer, at a centrally controlling and 2D locating controller; determining 2D locations by the controller of the N objects; and transmitting from the controller directions to the N objects for the N objects to move. An apparatus for tracking. The apparatus includes N objects, where N is greater than or equal to 2 and is an integer, each object having an emitter which emits light; and a mechanism for 2D sensing of the N objects over time from the light emitted by each emitter. The present invention pertains to a method for tracking.

Abstract: An apparatus for viewing an image. The apparatus includes a screen on which an image of a superimposed projection for left and right eye views of a viewer is displayed image. The apparatus includes means for projecting the projections onto the screen image. The apparatus includes a rear retarder disposed in front of the screen image. The apparatus includes a front retarder disposed in front of the rear retarder image. The apparatus includes means for applying an increasing ramp of phase retardance across an image in the rear retarder, and applying a decreasing ramp of phase retardance across the image in the front retarder so a constant phase retardance is created across an entire surface of the screen disposed behind the rear retarder and the front retarder when seen by a viewer in front of the front retarder. An apparatus for viewing an image. The apparatus includes an eye tracker which tracks positions of the eyes of a viewer image.
