The head-worn wearable device includes a light-emitting diode visible to the user while wearing the head-worn wearable device and is in communication with a wrist-wearable device worn by the user. The wrist-wearable device is configured to sense biometric data for the user during the physical activity. The method includes, after receiving the indication and while the user is performing the activity, in accordance with a determination that the biometric data satisfies a physiological-based threshold indicating that information about the biometric data would assist the user in performing the physical activity, causing the head-worn wearable device to present, via the light-emitting diode, the information about the biometric data.
WEARABLE DEVICE INCLUDING AN ARTIFICIALLY INTELLIGENT ASSISTANT FOR GENERATING RESPONSES BASED ON SHARED CONTEXTUAL DATA, AND SYSTEMS AND METHODS OF USE THEREOF
System and method including an artificially intelligent assistant are described. An example method includes, in response to a user input initiating an artificially intelligent (AI) assistant, capturing contextual data including one or more of image data and audio data. The method includes generating, based on the contextual data, user query data including a user query and a portion of the contextual data. The method includes determining, using an AI assistant model that receives the user query data, a user prompt based on, at least the user query and the portion of the contextual data, and generating, by the AI assistant model, a response to the user prompt. The method further includes causing presentation of the response to the user prompt at a head-wearable device.
An apparatus that facilitates and/or supports efficiently testing device radiation for spurious emissions may include a chamber that includes a plurality of interior sides. This apparatus may also include a plurality of antennas coupled to the plurality of interior sides, and the plurality of antennas may be configured to receive radiation emitted by a device under test. This apparatus may further include a controller communicatively coupled to the plurality of antennas, and the controller may be configured to obtain measurements of spurious emissions in the radiation. Various other apparatuses, systems, and methods are also disclosed.
An eyewear device that facilitates and/or supports improved antenna performance may include a temple that comprises an at least partial cavity. In some examples, the eyewear device may also include an antenna that is placed inside the at least partial cavity and/or dimensioned commensurate with a full wavelength of a carrier frequency to be applied to the antenna. Various other devices, systems, and methods are also disclosed.
A computer implemented method for facilitating system user interface (UI) interactions in an artificial reality (XR) environment is provided. The method includes rendering the system UI in the XR environment as a 3D virtual element. The method further includes tracking a position of a hand of a user and a pre-defined stable point on the user. The method further includes identifying, based on the tracking, that the hand has grasped a portion of the system UI and, in response, rotating the position of the system UI around the grasped portion of the system UI such that a line, between the stable point and the surface of the system UI, is moved, to be perpendicular or at a predefined angle from perpendicular to the surface of the system UI, as the user moves the system UI via the grasped portion.
Systems and methods for streaming-based object recognition may include a device which transmits, to a server, video data and first coordinates of a first viewport for the device at a first time instance. The video data may include one or more objects in the first viewport. The device may transmit second coordinates of a second viewport for the device at a second time instance. The device may receive, from the server, data corresponding to the one or more objects within the second viewpoint. The data may be received in a sequence according to coordinates of the one or more objects relative to the second viewport. The device may render the data relative to the one or more objects within a third viewport at a third time instance.
