Abstract: A sensor on a wearable device may be further configured as a sensor for detecting and recognizing a gesture to control the wearable device. For example, light detected by a photoplethysmography (PPG) sensor of a smart watch may include (i) light back reflected from underneath the smart watch and (ii) light back reflected from a touch to a wrist adjacent to the smart watch. The detected light may be filtered to isolate the light back reflected from the touch. A waterfall image that includes information about how the isolated light changes with time and amplitude may be generated and used to detect and recognize gestures performed on the wrist, such as a touch. This additional touch area may help to supplement a touch area provided by a display to control the smart watch.

Abstract: A method including determining historical user data associated with an event occurring on a wearable device, determining a probability of interacting with an object on a display of the wearable device based on the historical user data, scaling a hitbox associated with the object to form a scaled hitbox, detecting a user input based on an eye tracking being within the scaled hitbox, and in response to detecting the user input, initiating an action corresponding to the object.

Abstract: An electronic document is provided for presentation via a graphical user interface (GUI). A first region of the electronic document includes content objects. A second region of the electronic document includes a drawing object. A determination is made, based on first characteristics associated with the content objects and second characteristics associated with the drawing object, that the drawing object corresponds to the content objects. A mapping is generated between the content objects and the drawing object. A modification to the content objects in the first region of the electronic document is identified. In response to the modification to the content objects, a presentation of the drawing object in the second region of the electronic document is modified in view of the generated mapping.

Abstract: A method including generating two or more audio signals (e.g., by two or more microphones) based on a user interaction with a wearable device, generating an audio signature based on the two or more audio signals, and identifying at least one of a coordinate or a gesture based on an output of a machine-learned model given the audio signature.

Abstract: This document describes systems and techniques to generate refined location estimates using ultra-wideband (UWB) communication links. Mobile devices, such as smartphones, include location sensors to estimate their location. The accuracy of location sensors is generally about 3 meters (or about 10 feet). More accurate location data would allow mobile devices to provide new and improved functionality. The described systems and techniques determine the distance between nearby mobile devices using UWB communication links. A mobile device can then use the distance between the mobile devices to determine their relative locations. By comparing the relative locations of the mobile devices with their location estimates, the mobile device can generate a refined location estimate.

Abstract: A method for determining one or more vital signs of a person includes recording video images of a scene with an egocentric camera coupled to the person's body, detecting and magnifying image frame-to-image frame movements in the video images of the scene, representing the magnified image frame-to-image frame movements in the video images of the scene by a one-dimensional (1D) amplitude-versus-time series, and transforming the 1D amplitude-versus-time series representation into a frequency spectrum. The method further includes identifying one or more local frequency maxima in the frequency spectrum as corresponding to one or more vital signs of the person.

Abstract: Methods, devices, and systems for contactless cough detection and attribution are presented herein. Audio data may be received using a microphone. A cough may be identified as having occurred based on the received audio data. Radar data may be received indicative of reflected radio waves from a radar sensor. A state analysis process may be performed using the received radar data. The detected cough may be attributed to a particular user based at least in part on the state analysis process performed using the radar data.

Abstract: Systems and methods related to simulated light-in-flight imaging are described. A computing device may execute a light-in-flight engine to process an optical image and a corresponding depth map to produce a light-in-flight image or video that simulates propagation of a wavefront across a scene. The light-in-flight engine may generate an optical simulation output by transforming a depth map to a three-dimensional lift domain to produce a three-dimensional data structure, then convolving the three-dimensional data structure with a convolutional operator, which may define a Gaussian sphere, to produce a filtered three-dimensional data structure. The light-in-flight engine then affine transforms the optical image with an identified slice of the filtered three-dimensional data structure to produce a light-in-flight image.

Abstract: This document describes techniques and devices to detect and classify human and animal presence and/or motion based on changes in the interaction of the human or animal with Wireless Local Area Network (WLAN) radio frequency (RF) signals within or about a building structure, such as a home or office. A first WLAN device transmits a sounding packet to a second WLAN device and receives an acknowledgement (ACK) of receiving the sounding packet by the second WLAN device. The first WLAN device uses the received ACK to determine Channel State Information (CSI) for an RF signal path between the first WLAN device and the second WLAN device, aggregates the determined CSI with additional CSI, and uses the aggregated CSI to determine a presence or a motion within the structure.
