Abstract: The subject technology receives, by one or more hardware processors implementing a local wireless network, a request from a client device to mirror media content displayed on a screen of the client device on a wearable device. In response to the request, the subject technology causes a display of the media content in a mirroring lens of the wearable device. While the media content is being displayed in the mirroring lens of the wearable device, the subject technology tracks hand gestures of a user wearing the wearable device and viewing the media content displayed in the mirroring lens of the wearable device. The subject technology processes navigational or manipulation data based on the tracked hand gestures and sends a navigation or manipulation instruction to the client device or a mirroring lens processor of the wearable device based on the tracked hand gestures.

Abstract: A display system may include a head-mounted display (HMD) for rendering a three-dimensional virtual object which appears to be located in an ambient environment of a user of the display. One or more eyes of the user may not be in desired positions, relative to the HMD, to receive, or register, image information outputted by the HMD and/or to view an external environment. For example, the HMD-to-eye alignment may vary for different users and/or may change over time (e.g., as the HMD is displaced). The display system may determine a relative position or alignment between the HMD and the user's eyes. Based on the relative positions, the wearable device may determine if it is properly fitted to the user, may provide feedback on the quality of the fit to the user, and/or may take actions to reduce or minimize effects of any misalignment.

Abstract: Wearable systems and method for operation thereof incorporating headset and controller localization using headset cameras and controller fiducials are disclosed. A wearable system may include a headset and a controller. The wearable system may alternate between performing headset tracking and performing controller tracking by repeatedly capturing images using a headset camera of the headset during headset tracking frames and controller tracking frames. The wearable system may cause the headset camera to capture a first exposure image an exposure above a threshold and cause the headset camera to capture a second exposure image having an exposure below the threshold. The wearable system may determine a fiducial interval during which fiducials of the controller are to flash at a fiducial frequency and a fiducial period. The wearable system may cause the fiducials to flash during the fiducial interval in accordance with the fiducial frequency and the fiducial period.

Abstract: Methods, systems, and apparatuses are described herein for improving computer authentication processes by generating authentication questions based on the location of a user. Transaction data indicating a plurality of transactions associated with a user account may be received. Location data indicating a plurality of locations of a user device might be received. At least a subset of the plurality of transactions may be tagged, based on the location data, with an indication that a user was present for a respective transaction. For example, a location of a merchant might be compared to a user device location indicated by the location data. A plurality of authentication questions might be generated based on the subset of the plurality of transactions. Access to the user account might be provided based on responses to the plurality of authentication questions.

Abstract: Machine learning-based methods are disclosed to intelligently generate dynamic workflows, such as dynamic call lists and priority levels of alarm notifications. To generate a dynamic call list based on an alarm notification, the system may identify electronic devices present in an area using emitted passive electromagnetic signals (e.g., RF signals such as Bluetooth, WiFi, and/or cellular). The identification of the electronic devices may be associated with known and/or unknown individuals on the premises. The RF signal data may be processed using at least one ML model to determine the severity of the alarm. Based on the processed data, the system may assign a priority level to the alarm, where the priority level may range from level 0 (no action) to level 4 (dispatch law enforcement immediately). The disclosed methods use trained machine learning models to generate a dynamic call list and identify false alarms with increased accuracy.

Abstract: Aspects described herein may relate to techniques for detecting login activity to a financial account during a knowledge-based authentication process. The login activity may be related to access to an online interface for the financial account. The detection of login activity during the authentication process my indicate that the integrity of the authentication process is compromised as login access may provide an individual with transaction data that may be used to answer transaction-based authentication questions. As a result of detecting login activity, an alternative authentication process may be initiated or an authentication request related to the financial account may be denied.

Abstract: Aspects of the subject disclosure may include, for example, identifying an entity of a natural language question, locating a node of a knowledge graph corresponding to the entity, and generating a candidate answer set including a group of other entities located a predetermined proximity to the node. Contextual information for the group of other entities is determined from the knowledge graph, and the natural language question and contextual information are separately encoded to obtain separate encoded vectorial representations of the natural language question and members of the candidate answer set. The encoding uses pre-trained language model embeddings obtained via a bidirectional encoder representations from transformer encoding process. The encoded vectorial representations of the question under an influence of aspects of the contextual information are scored and a member of the candidate answer set selected according to the score to obtain an answer to the original question.

Abstract: A wearable device may include a head-mounted display (HMD) for rendering a three-dimensional (3D) virtual object which appears to be located in an ambient environment of a user of the display. The relative positions of the HMD and one or more eyes of the user may not be in desired positions to receive, or register, image information outputted by the HMD. For example, the HMD-to-eye alignment may vary for different users and may change over time (e.g., as a user moves around and/or the HMD slips or is otherwise displaced). The wearable device may determine a relative position or alignment between the HMD and the user's eyes. Based on the relative positions, the wearable device may determine if it is properly fitted to the user, may provide feedback on the quality of the fit to the user, and may take actions to reduce or minimize effects of any misalignment.

Abstract: A method for placing content in an augmented reality system. A notification is received regarding availability of new content to display in the augmented reality system. A confirmation is received that indicates acceptance of the new content. Three dimensional information that describes the physical environment is provided, to an external computing device, to enable the external computing device to be used for selecting an assigned location in the physical environment for the new content. Location information is received, from the external computing device, that indicates the assigned location. A display location on a display system of the augmented reality system at which to display the new content so that the new content appears to the user to be displayed as an overlay at the assigned location in the physical environment is determined, based on the location information. The new content is displayed on the display system at the display location.
