Patent number: 11532118Abstract: Augmented and virtual reality display systems increase viewer comfort by reducing viewer exposure to virtual content that causes undesirable accommodation-vergence mismatches (AVM). The display systems limit displaying content that exceeds an accommodation-vergence mismatch threshold, which may define a volume around the viewer.

For example, content may be clipped if the viewer is verging within an AVM zone and if the content is displayed within the AVM zone for more than a threshold duration. A further possible condition for clipping content is that the user is verging on that content.Type: GrantFiled: December 23, 2020Date of Patent: December 20, 2022Assignee: Magic Leap, Inc.Inventors: Brian David Schwab, Randall E.

Patent number: 10714029Abstract: A display device includes a display unit having a display surface on which pixels are arranged in row and column directions. Each pixel includes subpixels having different colors. Subpixels in the pixels include a first subpixel including an electrode having an opening with a longitudinal direction along a first direction and a second subpixel including an electrode having an opening with a longitudinal direction along a second direction. The first and second directions are different from the row and column directions. Subpixels arranged in a third direction are the first or second subpixels. The number of subpixels constituting one color pattern in a fourth direction is 2?. The number of subpixels in which the first and second subpixels arranged in the fourth direction constitute one cycle is 4?. The third direction is one of the row and column directions, and the fourth direction is the other direction.Type: GrantFiled: October 3, 2018Date of Patent: July 14, 2020Assignee: Japan Display Inc.Inventors: Kojiro Ikeda, Masaaki Kabe

Patent number: 10699567Abstract: The present disclosure relates to a method of controlling a traffic surveillance system. The method comprises the steps of: capturing first images and second images over time by a plurality of the stereoscopic sensors; processing, by the processing unit, a first image and a second image from a first stereoscopic sensor of the plurality of the stereoscopic sensors to produce a first height image; analyzing said first height image to detect a moving object such as a vehicle located within the primary view; and analysing a part of a primary view of at least a first image, a second image or a combination of the first image and the second image captured by a second stereoscopic sensor based on the detected moving object in said first height image to determine a characteristic of the moving object.Type: GrantFiled: November 27, 2015Date of Patent: June 30, 2020Assignee: Kapsch TrafficCom ABInventors: Johan Bäckvall, Ulf Ärlig, Björn Crona, Christian Karlström

Patent number: 10681328Abstract: A direct retinal projector system that provides dynamic focusing for virtual reality (VR) and/or augmented reality (AR) is described. A direct retinal projector system scans images, pixel by pixel, directly onto the subject's retinas. This allows individual pixels to be optically affected dynamically as the images are scanned to the subject's retinas. Dynamic focusing components and techniques are described that may be used in a direct retinal projector system to dynamically and correctly focus each pixel in VR images as the images are being scanned to a subject's eyes. This allows objects, surfaces, etc. that are intended to appear at different distances in a scene to be projected to the subject's eyes at the correct depths.Type: GrantFiled: October 10, 2019Date of Patent: June 9, 2020Assignee: Apple Inc.Inventor: Alexander Shpunt

Patent number: 10648790Abstract: A system for determining a three-dimensional position of a tip of a testing tool in an anatomic training model can be used for injection training. The system can include first and second cameras positioned in the anatomic training model. The first and second cameras can each detect an area of light emitted from the tip of the testing tool. The system can also include a processing unit configured to trace the emitted light away from a location of a centroid of the area of emitted light in the first camera and a location of a centroid of the area of emitted light in the second camera respectively, and calculate a three-dimensional position of the distal tip of the testing tool based on the locations of the centroids. The calculation can take into account refraction of the emitted light through an innermost layer of the training model.Type: GrantFiled: March 1, 2017Date of Patent: May 12, 2020Assignee: Truinject Corp.Inventors: Clark B.
