Systems, methods, and graphical user interfaces for updating display of a device relative to a user's body

An electronic device, comprising:

• a display generation component arranged on the electronic device opposite a predefined portion of a user's body;
• one or more input devices;
• one or more processors;
• and
• memory storing one or more programs, wherein the one or more programs are configured to be executed by the one or more processors, the one or more programs including instructions for:
• while the electronic device is worn over the predefined portion of the user's body, displaying, via the display generation component, a graphical representation of an exterior view of a body part that corresponds to the predefined portion of the user's body;
• detecting a trigger at the electronic device, wherein the trigger comprises an input selected from the group consisting of an input detected in front of the display generation component of the electronic device, an input selecting a physical control of the electronic device, and an input detected on an edge of the electronic device;
• and
• in response to detecting the trigger, modifying the graphical representation of the exterior view of the body part that corresponds to the predefined portion of the user's body in accordance with the detected trigger, including obscuring a portion of the graphical representation of the exterior view of the body part that corresponds to the predefined portion of the user's body.

A non-transitory computer readable storage medium storing one or more programs, the one or more programs comprising instructions that, when executed by an electronic device that includes and/or is in communication with a display generation component arranged on the electronic device opposite a predefined portion of a user's body, and one or more input devices, cause the electronic device to:

• while the electronic device is worn over the predefined portion of the user's body, display, via the display generation component, a graphical representation of an exterior view of a body part that corresponds to the predefined portion of the user's body;
• detect a trigger at the electronic device, wherein the trigger comprises an input selected from the group consisting of an input detected in front of the display generation component of the electronic device, an input selecting a physical control of the electronic device, and an input detected on an edge of the electronic device;
• and
• in response to detecting the trigger, modify the graphical representation of the exterior view of the body part that corresponds to the predefined portion of the user's body in accordance with the detected trigger, including obscuring a portion of the graphical representation of the exterior view of the body part that corresponds to the predefined portion of the user's body.
