  • Patent number: 11978169
    Abstract: A wrist-pose isolation system can infer a wrist pose (e.g., the user's hand position relative to her forearm) and can reduce wrist-induced jitter for projection casting in an XR environment. A user's projection cast can be determined as a combination of a “low-wrist contribution” component (e.g., a body-and-arm component) and a “high-wrist contribution” component (e.g., the pose of the wrist with respect to the arm). Using input from a gesture-tracking system, the contribution of the user's wrist pose to the user's current projection cast is calculated as a “wrist-contribution vector.” A projection cast direction can be determined as the interpolation of the current low-wrist contribution component and the high-wrist contribution component. This interpolation can be performed by weighting each by a specified amount and combining them.

    Abstract: According to examples, a wearable device may include an imaging component, at least one wireless communication component, and a controller. The controller may activate the at least one wireless communication component to perform a wireless scan of at least one radio available to respond to the wireless scan. The controller may also receive, through the at least one wireless communication component, wireless scan data from the at least one radio and may embed the wireless scan data as part of a media metadata. The wireless scan data may be used to determine a location estimate of the at least one radio and thus, the wearable device. The location estimate of the wearable device may also be used to geotag media captured by the wearable device without using a GPS receiver on the wearable device or when a GPS receiver is unable to track a current location.

  • Patent number: 11967014
    Abstract: A 3D conversation system can facilitate 3D conversations in an augmented reality environment, allowing conversation participants to appear as if they are face-to-face. The 3D conversation system can accomplish this with a pipeline of data processing stages, which can include calibrate, capture, tag and filter, compress, decompress, reconstruct, render, and display stages. Generally, the pipeline can capture images of the sending user, create intermediate representations, transform the representations to convert from the orientation the images were taken from to a viewpoint of the receiving user, and output images of the sending user, from the viewpoint of the receiving user, in synchronization with audio captured from the sending user. Such a 3D conversation can take place between two or more sender/receiving systems and, in some implementations can be mediated by one or more server systems. In various configurations, stages of the pipeline can be customized based on a conversation context.

  • Publication number: 20240126367
    Abstract: An eye tracking system employing three-dimensional (3D) sensing using time of flight is provided. Instead of directly measuring the time of arrival of the emitted photons, the light intensity of the transmitted laser beam is modulated, and a phase change of the return beam computed by comparison with the transmit waveform. The modulation frequency is resolved with radio frequency (RF) mixing and digital signal processing techniques. A variety of phase detection systems and techniques including, but not limited to, quadrature analog front end detection and analog homodyne phase detection are applied. The modulation frequency may, depending on phase detection technique, be sinusoidal or pulsed.
