Head-mounted augmented reality (AR) devices can track pose of a wearer's head to provide a three-dimensional virtual representation of objects in the wearer's environment. An electromagnetic (EM) tracking system can track head or body pose. A handheld user input device can include an EM emitter that generates an EM field, and the head-mounted AR device can include an EM sensor that senses the EM field. EM information from the sensor can be analyzed to determine location and/or orientation of the sensor and thereby the wearer's pose. An improved or optimized pose can be provided by reverse-estimating a reverse EM measurement matrix and optimizing the pose based on a comparison between the reverse EM measurement matrix and an EM measurement matrix measured by the EM sensor.

A method for augmenting procedures at production equipment includes: linking a first description of a first step in a procedure and a capture type to a first capture field; generating a digital draft procedure comprising descriptions of steps extracted from the procedure and the first capture field specifying data capture of the first capture type from an equipment unit; generating augmented guidance for the first step in the procedure based on visual content recorded by a mobile device—assigned to an exemplary operator—during completion of the first step in the digital draft procedure; linking the augmented guidance to a location proximal the equipment unit based on locations of the first mobile device during completion of the first step in the digital draft procedure; and generating an augmented digital procedure based on steps in the procedure, the augmented guidance, and definitions for data capture according to the first capture field.

In one embodiment, a computing system may access an image to be displayed by a display. The system may determine one or more first characteristics associated with a content of the image. The one or more first characteristics may include a contrast level of the content of the image with respect to a background of the image. The system may determine a first display persistence time period for the display to display the image based on the one or more first characteristics associated with the content of the image. The system may configure the display to display the image using the first display persistence time period.

A game processing system for processing of a game that provides interaction with a virtual character according to one embodiment includes a storage that stores action data for specifying one or more actions of the virtual character and one or more computer processors. The game includes a VR mode in which the game progresses in accordance with detection information obtained by a head mounted display. The one or more processors determine an action of the player performed toward the virtual character based on the detection information obtained by the head mounted display attached to the head of the player, cause the virtual character to interact with the player based on the action of the player; and suspend execution of the VR mode if a suspension condition is satisfied.

An augmented reality or virtual reality (AR/VR) device pairs with a companion device to augment input interfaces associated with an AR/VR application at the AR/VR device. In implementations, an AR/VR device determines a portion of a markup file that corresponds to an AR/VR scene of a plurality of AR/VR scenes in an AR/VR environment, and communicates the portion of the markup file to the companion device to cause the companion device to configure a companion user interface associated with initiating an action as part of the AR/VR scene. In response to receiving user input via the companion user interface, the companion device communicates the action to the AR/VR device to initiate the action. The AR/VR device receives input data from the companion device, and initiates the action for the AR/VR scene.

A method which makes it possible to immerse a user in a virtual reality application is described. The method includes controlling the movement of an avatar of a user in a synthetic scene and controlling the movements of a video acquisition system depending on the detected movements of the head of the user. The method also includes playing back content on a screen of a virtual reality helmet of the user, the content being a video stream acquired by the video acquisition system if the position of the eyes of the avatar is in a synthetic object whose volume can be included in a volume in which the video acquisition system is likely to move.

A wearable electronic device is disclosed. The device can include a support structure and an electronic component disposed in or on the support structure. A heat exchanger element can be thermally coupled with the electronic component, the heat exchanger element comprising a fluid inlet port and a fluid outlet port. A first conduit can be fluidly connected to the fluid inlet port of the heat exchanger, the first conduit configured to convey, to the heat exchanger, liquid at a first temperature. A second conduit can be fluidly connected to the fluid outlet port of the heat exchanger, the second conduit configured to convey, away from the heat exchanger, liquid at a second temperature different from the first temperature.

A data acquisition method and apparatus for a head-mounted display device, a host and a head-mounted display device are provided. The method includes: acquiring user head posture information collected by a head posture sensor; determining a predicted head position at a next rendering moment based on the user head posture information and a current display scene of the head-mounted display device; and acquiring a current video rendering corresponding to the current rendering moment based on the predicted head position and video data at the current rendering moment, in order that the head-mounted display device displays a rendered video at the current rendering moment and a target time warped frame, where the current video rendering includes the rendered video and one or more time warped frames for the next rendering moment, and the target time warped frame is one of the one or more time warped frames.

A system and method of operation of an augmented reality system includes: a position sensor (140) for calculating a current location (144); an orientation sensor (142), coupled to the position sensor (140), for calculating a current orientation (146); and a control mechanism (118), coupled to the position sensor (140), for presenting a system object (126) based on the current location (144), the current orientation (146), an object location (128), an object orientation (130), an access right (120), a visibility (134), and a persistence (136).

The disclosed systems and methods provide hands-free medication tracking. A method includes providing an augmented reality device attachable to a face of a user. The method also includes determining, using one or more sensors of the augmented reality device, a user action to be carried out with respect to a medication. The method also includes presenting, via a display interface of the augmented reality device, a visual indicator to assist with the user action. The method also includes confirming, via the one or more sensors of the augmented reality device, a completion of the user action. The method also includes sending, via a communication interface of the augmented reality device, an update message to a server indicating the completion of the user action, wherein the update message causes the server to update a medication inventory in a database.
