Abstract: In some embodiments, an electronic device optionally identifies a person's face, and optionally performs an action in accordance with the identification. In some embodiments, an electronic device optionally determines a gaze location in a user interface, and optionally performs an action in accordance with the determination. In some embodiments, an electronic device optionally designates a user as being present at a sound-playback device in accordance with a determination that sound-detection criteria and verification criteria have been satisfied. In some embodiments, an electronic device optionally determines whether a person is further or closer than a threshold distance from a display device, and optionally provides a first or second user interface for display on the display device in accordance with the determination. In some embodiments, an electronic device optionally modifies the playing of media content in accordance with a determination that one or more presence criteria are not satisfied.

Abstract: Portable electronic devices are provided. Each device may be formed from two parts. A first part may be provided with components such as a display, a touch screen, a cover glass, and a frame. A second part may be provided with a plastic housing, circuit boards containing electrical components, and a bezel. Engagement members may be connected to the first and second parts. The engagement members may be formed from metal clips with holes and springs with flexible spring prongs that mate with the holes in the clips. The metal clips may be welded to frame struts on the frame and the springs may be welded to the bezel. During assembly, the first part may be rotated into place within the second part. Retention clips attached to the frame may be used to secure the two parts together. Assembly instructions and associated connector numbers may be provided within the devices.

Abstract: The present disclosure relates to user interfaces for manipulating user interface objects. A device, including a display and a rotatable input mechanism, is described in relation to manipulating user interface objects. In some examples, the manipulation of the object is a scroll, zoom, or rotate of the object. In other examples, objects are selected in accordance with simulated magnetic properties.
