  • Patent number: 11887322
    Abstract: Method of generating depth estimate based on biometric data starts with server receiving positioning data from first device associated with first user. First device generates positioning data based on analysis of a data stream comprising images of second user that is associated with second device. Server then receives a biometric data of second user from second device. Biometric data is based on output from a sensor or a camera included in second device. Server then determines a distance of second user from first device using positioning data and biometric data of the second user. Other embodiments are described herein.

  • Publication number: 20240031870
    Abstract: In a media data transmission method, an access network device receives layered coding information of a media flow, where the media flow is a target service; the access network device determines a plurality of multicast groups based on the layered coding information and information about terminal devices that access the target service; and the access network device sends a media data packet of the target service to the terminal devices based on the plurality of multicast groups. By using the method, multicast grouping may be performed on a plurality of terminal devices that access a same service, and further differentiated transmission is performed on media data of the same service. This improves a data transmission speed of the access network device, and improves a data throughput in a signal coverage area of the access network device.

    Abstract: A communication method includes receiving indication information from a session management function (SMF) network element. The indication information indicates that downlink data of a first terminal device arrives at a core network side. The communication method also includes, in response to an extended discontinuous reception (eDRX) cycle of the first terminal device being greater than or equal to a first threshold, sending an eDRX parameter to a first access network device based on capability information of the first terminal device and capability information of the first access network device. The first access network device is any access network device in a tracking area (TA) list of the first terminal device.

  • Patent number: 11861795
    Abstract: Systems, methods, devices, and media for anamorphosis systems to generate and cause display of anamorphic media are disclosed. In one embodiment, an anamorphosis system is configured to identify a set of features of a space, determine relative positions of the set of features, determine a perspective of the mobile device within the space based on the relative positions of the set of features, retrieve anamorphic media based on the location of the mobile device, and apply the anamorphic media to a presentation of the space at the mobile device. The anamorphic media may include media items such as images and videos, configured such that the media items are only visible from one or more specified perspectives. The anamorphic media may include a stylized text string projected onto surfaces of a space such that the stylized text string is correctly displayed when viewed through a user device from a specified perspective.

  • Patent number: 11854231
    Abstract: Determining the position and orientation (or “pose”) of an augmented reality device includes capturing an image of a scene having a number of features and extracting descriptors of features of the scene represented in the image. The descriptors are matched to landmarks in a 3D model of the scene to generate sets of matches between the descriptors and the landmarks. Estimated poses are determined from at least some of the sets of matches between the descriptors and the landmarks. Estimated poses having deviations from an observed location measurement that are greater than a threshold value may be eliminated. Features used in the determination of estimated poses may also be weighted by the inverse of the distance between the feature and the device, so that closer features are accorded more weight.

  • Publication number: 20230412662
    Abstract: A data processing method and a device are provided, to meet a jitter buffer requirement of playing a real-time media service with a large amount of data, and improve real-time performance and accuracy of data transmission of the real-time media service. The method is performed in a radio access network RAN device, and includes: The RAN obtains first information of first media data, where the first information indicates a size of the first media data (S210); determines a playback policy for the first media data based on the first information, where the playback policy indicates a buffer size or a playback rate (S220); and sends the playback policy to a terminal device UE (S230).

  • Publication number: 20230368476
    Abstract: An augmented reality device generates an updated position and orientation (pose) value by initially determining, using image-based processing, a pose estimate from a current image frame, a previous image frame and a previous pose. An IMU pose is then obtained from data generated by an inertial measurement unit including motion sensors, and transformation between the pose estimate and the IMU pose is determined. The transformation is applied to the pose estimate to generate a pose update. Media content is applied to a position within an image, the position being based on the pose update.

  • Patent number: 11810316
    Abstract: The pose of a wide-angle image is determined by dewarping regions of the wide-angle image, determining estimated poses of the dewarped regions of the wide-angle image and deriving a pose of the wide-angle image from the estimated poses of the of the dewarped regions. The estimated poses of the dewarped regions may be determined by comparing features in the dewarped regions with features in prior dewarped regions from one or more prior wide-angle images, as well as by comparing features in the dewarped regions with features in a point cloud.
