Abstract: In some implementations, a user device can coordinate adjustments to a composite GUI generated in cooperation with an accessory device that presents the composite graphical user interface. For example, the user device can receive configuration data that defines the maximum GUI display area (e.g., size, dimensions) of the accessory device, various view areas within the GUI display area of the accessory device into which the user device can render GUIs, and/or transitions between the various view areas. The user device can generate a display buffer based on the maximum GUI display area, generate a graphical user interface in an area of the buffer corresponding to a current view area specified by the accessory device, and send to the accessory device video frames corresponding to the display buffer. The accessory device can generate a composite GUI based on the received video frames that include the user device generated GUI.

Abstract: Wireless communications may be established between mobile computing devices via wireless protocol communication modes, using the orientation of the mobile devices to determine the communication modes in which the mobile devices are operated. Requests may be received to initiate wireless communications using a wireless protocol that supports at least two communication modes. The orientation of the mobile devices may be determined, and the communication modes to be used by the mobile devices may be based on the orientations of the mobile device. Each mobile device may be configured to operate in the determined communication mode of the wireless protocol, for establishing communications via the wireless protocol with other mobile devices.

Abstract: A mobile device can include ranging circuitry to determine distance to another mobile device. A first wireless protocol can establish an initial communication session to perform authentication and/or exchange ranging settings. A second protocol can perform ranging, and other wireless protocols can transmit content. In one example, the distance information can be used to display a relative position of another device on a user interface of a sending device. The user interface can allow a user to quickly and accurately select the recipient device for sending the data item. As another example, the distance information obtained from ranging can be used to trigger a notification (e.g., a reminder) to be output from a first mobile device or used to display a visual indicator on a receiving device. Proximity of a device (e.g., as determined by a distance) can be used to suggest recipient for a new communication.

Abstract: An electronic device, while the electronic device is worn over a predefined portion of the user's body, displays, via a display generation component arranged on the electronic device opposite the predefined portion of the user's body, a graphical representation of an exterior view of a body part that corresponds to the predefined portion of the user's body. The electronic device detects a change in position of the electronic device with respect to the predefined portion of the user's body. The electronic device, in response to detecting the change in the position of the electronic device with respect to the predefined portion of the user's body, modifies the graphical representation of the exterior view of the body part that corresponds to predefined portion of the user's body in accordance with the detected change in position of the electronic device with respect to the predefined portion of the user's body.

Abstract: Video coding schemes may include one or more filters to reduce coding artifacts and improve video quality. These filters may be applied to decode video data in a predetermined sequence. The output from one or more of these filters may be selected for different images, blocks, or sets of video data and then copied and/or routed to a display or a buffer storing reference data that is used to decode other video data in a data stream. Providing the ability to select which filter output is used for display and as a reference may result in better video quality for multiple types of video data. The filters that are selected for display and for reference may be different and may vary for different images, blocks, and data sets.
