Patent number: 11170521Abstract: In an exemplary process for determining a position of an object in a computer-generated reality environment using an eye gaze, a user uses their eyes to interact with user interface objects displayed on an electronic device. A first direction of gaze is determined for a first eye of a user detected via the one or more cameras, and a second direction of gaze is determined for a second eye of the user detected via the one or more cameras. A convergence point of the first and second directions of gaze is determined, and a distance between a position of the user and a position of an object in the computer-generated reality environment is determined based on the convergence point. A task is performed based on the determined distance between the position of the user and the position of the object in the computer-generated reality environment.Type: GrantFiled: August 5, 2019Date of Patent: November 9, 2021Assignee: Apple Inc.Inventors: Mohamed Selim Ben Himane, Anselm Grundhöfer

Patent number: 11115633Abstract: The present disclosure relates to a method for calibrating a projector. The method includes projecting a test pattern onto a scene or an object within the scene and capturing the test pattern using a camera. Once the test pattern image has been captured by the camera, the method further includes estimating by a processing element a perspective projection matrix, warping the estimated projection matrix based on a non-linear distortion function, and modifying the projector to project light based on the distortion function. The present disclosure also relates to a presentation or projection system including two types of projectors for projecting an output presentation having a second image overlaid on a first image.Type: GrantFiled: August 9, 2018Date of Patent: September 7, 2021Assignee: DISNEY ENTERPRISES, INC.Inventor: Anselm Grundhöfer

Publication number: 20210150295Abstract: Various implementations disclosed herein include devices, systems, and methods that select colors for visual markers that include colored markings encoding data. In some implementations, the colors are automatically or semi-automatically selected. In some implementations, the colors are selected to remain sufficiently detectable despite changes in lighting conditions or printing/display conditions. In some implementations, a set of colors selectable for use in a visual marker is obtained. Then, measures of distance between a plurality of colors of the set of colors is determined, and a subset of the set of colors for the visual marker is selected based on the measure of distance between colors of the subset of colors. In some implementations, the visual marker appearance includes graphical elements encoding data using the subset of colors. In some implementations, input is received using a GUI on a display to determine multiple colors based on a source image.Type: ApplicationFiled: November 3, 2020Publication date: May 20, 2021Inventors: Arun Srivatsan Rangaprasad, Anselm Grundhoefer, Dhruv A.

Publication number: 20210097714Abstract: Various implementations disclosed herein include devices, systems, and methods that determine the relative positioning (e.g., offset) between a mobile electronic device and a visual marker. In some implementations, the determined relative positioning and a known position of the visual marker are used to determine a position (e.g., geo coordinates) of the mobile electronic device that is more accurate than existing techniques. In some implementations, the determined relative positioning is used with a position of the mobile electronic device to crowd source the stored position of the visual marker. In some implementations, the determined relative positioning and a position of the visual marker are used to determine a position of an object detected in an image by the mobile electronic device. In some implementations at an electronic device having a processor, locally-determined locations of a visual marker are received from mobile electronic devices that scan a visual marker.Type: ApplicationFiled: September 25, 2020Publication date: April 1, 2021Inventors: Anselm Grundhoefer, Jeffrey S.

Publication number: 20210090342Abstract: Various implementations disclosed herein adjust the luminance values of an image to improve the appearance of the image on an augmented reality device. In some implementations, the luminance values of an image are adjusted so that the image can be displayed on an augmented reality device (e.g., with background luminance) such that the image will be perceived more similarly to how the image would be perceived otherwise (e.g., on a device without background luminance). In some implementations, an image is adjusted based on an estimate of human perception of luminance that is not linear.Type: ApplicationFiled: September 11, 2020Publication date: March 25, 2021Inventors: Ralf Habel, Anselm Grundhoefer
