Abstract: A handheld electronic device may include a microphone for receiving voice commands, a speaker for providing audio feedback, a display for providing visual output and receiving touch input, and a motion sensor for receiving gesture input. The handheld electronic device may include control circuitry that processes voice commands differently depending on the application running on the handheld electronic device and the icon being displayed on the display. The control circuitry may determine the location of the handheld electronic device and may provide content based on the location. For example, a remote control interface for controlling an external device may be displayed when the handheld electronic device approaches the external device. A head-mounted device may display virtual images based on the location of the handheld electronic device. The virtual images may include a live video feed from a video call, virtual images associated with voice commands, or other virtual images.

Abstract: While a representation of a three-dimensional environment is visible via the first display generation component, a computer system, displays, via a second display generation component, one or more graphical elements that provide a visual indication of a status associated with a user who is in a position to view the representation of the three-dimensional environment, including changing the one or more graphical elements to represent changes in the status associated with the user. In response to detecting a first event that corresponds to the start of media capture using the computer system, the computer system displays, via the second display generation component, a first visual alert that indicates the start of media capture, wherein the first visual alert is displayed concurrently with at least a portion of the one or more graphical elements.
