A method of a user device to track objects in an extended reality (XR) environment includes capturing an image of a physical environment associated with the XR environment, sending the image, a first timestamp for the image, and object information for at least one object in the image to a tracking service, receiving an object identifier, object tracking information, and a second timestamp for the at least one object from the tracking service, performing time and motion compensation on the object tracking information to correlate the object tracking information and object identifier with the at least one object in the image of the physical environment, and generating or updating an XR overlay for the at least one object using time and motion compensated object tracking information.

Extended reality overlay optimization via distributed computing

Embodiments include methods of activating a display screen of a device. Such methods include establishing respective connections with one or more candidate devices, each having a candidate display screen, and obtaining angle of arrival information of respective signals transmitted from the candidate display screens or from the candidate devices. Such methods include selecting a display screen from the candidate display screens based on the angle of arrival information indicating that selected display screen is in a direction of gaze of the eye of the user, causing a confirmation code to be displayed on the selected display screen, and obtaining an image of the selected display screen having the confirmation code displayed thereon. Such methods include activating the selected display screen from an off or locked state based on detecting the confirmation code in the obtained image. Other embodiments include host systems configured to perform such methods.

Personal device activation and unlocking using gaze tracking

A method, performed by an electronic device for triggering a function of the electronic device, wherein the electronic device comprises a button which comprises a mechanical switch actuator for triggering a function related to the button, an electromagnetic sensor for sensing touch and/or proximity of an object interacting with the button and a responsive material structure for providing haptic feedback to the object is provided. The electronic device senses touch and/or proximity of the object with the electromagnetic sensor. The electronic device generates a haptic feedback with the responsive material structure in response to sensing the touch and/or proximity of the object. The haptic feedback is associated with the function which is triggered by the mechanical switch actuator. The electronic device triggers the function in response to the mechanical switch actuator being actuated.

Button with mechanical switch, electromagnetic sensor and haptic feedback, and method

An image processing system () and method therein for processing streaming media content to reduce disturbing spatial and/or temporal phenomena before being displayed on a device display. The image processing system () receives media stream comprising sequences of video frames into a buffer () and analyzes the video frames during streaming. The analyzing () is performed either on completely decoded or partially decoded video frames within a Group of Picture (GOP) to detect disturbing spatial and/or temporal phenomena. If a disturbing spatial and/or temporal phenomenon is detected, the image processing system () processes () the decoded video frames to reduce the disturbing spatial and/or temporal phenomenon based on user settings of the device and displays the processed video frames on the display ().

System and method to minimize repetitive flashes in streaming media content

A system comprising a first image processing arrangement and a second image processing arrangement, wherein the first image processing arrangement comprises a controller configured to: a) receive an image; b) select a task and a task identifier associated with task data; c) compress the image based on the task data; and d) transmit the compressed image to the second image processing arrangement for processing, and wherein the second image processing arrangement comprises a controller configured to: e) receive the compressed image and task identifier; f) retrieve task parameters associated with the task identifier; g) process the compressed image based on the task parameters; h) determine results and i) transmit the at least indications of the determined results to the first image processing arrangement, and the controller of the first image processing arrangement is further configured to: j) receive at least indications of a result of the processing from the second image processing arrangement; and k) indicate the result.

An optical sensor module has a controller, a sensor array, present state decision circuitry, and a pattern recognizer. The sensor array comprises a plurality of CMOS sensor pixels, wherein the sensor array is configured to supply one of a plurality of analog sensor signals at each of a sequence of sample times, wherein at each of the sample times, the one of the plurality of analog sensor signals is derived from one or more of the plurality of CMOS sensor pixels. The present state decision circuitry is configured to compare the one of the plurality of the analog sensor signals with a respective controller-selected reference voltage and to generate therefrom a respective single state decision signal. The pattern recognizer is configured to assert a pattern recognition signal whenever a plurality of sequentially generated single state decision signals matches a currently active one of a set of one or more reference sequences of single state decision signals. The controller is configured to assert a host system trigger signal when the pattern recognition signal is asserted a predefined number of times in sequence.

Low-power always-on image sensor and pattern recognizer

A device having a first side; a second side; a display configured to display any of a plurality of images on the first side; and a touch-sensitive input device disposed on the second side, wherein the touch-sensitive input device comprises a mapped touch area and an adjustment touch area. The device operation comprises obtaining an initial mapping that relates touch points of the mapped touch area to corresponding display points of a mapped area of the display, wherein the mapped area of the display is smaller than a total area of the display and has an initial position with respect to the display. First touch input data is received from the adjustment touch area, and a current position of the mapped area of the display is produced by adjusting the initial position of the mapped area of the display based on the first touch input data. A current mapping is produced by adjusting the initial mapping based on the current position of the mapped area. Second touch input data is received from the mapped touch area. The second touch input data is translated into a derived display position according to the current mapping. An action that is associated with the derived display position is then performed.

A method () of activating a display screen of a device, includes establishing () a connection with each of one or more candidate display screens (). A direction of gaze () of an eye of a user () is tracked (), and a display screen () is selected () from the one or more candidate display screens when () the display screen () is in the direction of gaze () of the eye of the user (). A confirmation code () is caused () to be displayed on the selected display screen and an image of the selected display screen is obtained. The selected display screen is activated () in response to detecting () the confirmation code () in the updated image of the selected display screen.
