Abstract: An electronic device may have a glass housing structures. The glass housing structures may be used to cover a display and other internal electronic device components. The glass housing structure may have multiple glass pieces that are joined using a glass fusing process. A peripheral glass member may be fused along the edge of a planar glass member to enhance the thickness of the edge. A rounded edge feature may be formed by machining the thickened edge. Raised fused glass features may surround openings in the planar glass member. Multiple planar glass members may be fused together to form a five-sided box in which electronic components may be mounted. Raised support structure ribs may be formed by fusing glass structures to a planar glass member. Opaque masking material and colored glass may be used to create portions of the glass housing structures that hide internal device components from view.

Abstract: A head-mounted device may be worn on the face of a user. The head-mounted device may include a user-viewable display that presents inwardly directed user-viewable images such as virtual reality images to the user. The head-mounted device may also have a publicly viewable display that presents publicly viewable images to individuals near the user. The publicly viewable images may overlap facial features of the user's face. Publicly viewable images may include captured images of user facial features or other content, may include computer-generated graphics such as user facial feature graphics, may contain a mixture of captured image content and overlaid graphics such as user facial feature graphics, or may contain other publicly viewable content. User monitoring sensors such as camera and gaze detection sensors, environmental sensors, and other circuitry in the head-mounted device may gather information that is used in adjusting the publicly viewable images.

Abstract: The present disclosure relates to music user interfaces. A device, comprising a display and a rotatable input mechanism, one or more processors, memory, and one or more programs, is described. In response to receiving the first user input, the one or more programs may include instructions for ceasing display of an audio playback user interface and displaying a first user interface of a first set of user interfaces. While displaying the user interface of the first user interfaces, the one or more programs may include instructions for: receiving a second user input representing a directional swipe in a second direction and, in response to receiving the second user input, ceasing display of the first user interface of a first set of user interfaces and displaying the audio playback user interface.
