Application programming interface for setting the prominence of user interface elements

A device comprising:

• one or more environmental sensors;
• a display;
• one or more processors;
• a non-transitory memory;
• and
• one or more programs stored in the non-transitory memory, which, when executed by the one or more processors, cause the device to:
• display, via the display, a user interface (UI) element as an overlay at a first location in a UI associated with a first field-of-view of the device, wherein the first field-of-view is characterized by a first viewing vector of a physical environment;
• detect a change from the first field-of-view of the device to a second field-of-view of the device, wherein the second field-of-view is characterized by a second viewing vector of the physical environment that is different from the first viewing vector;
• and
• in response to detecting the change from the first field-of-view to the second field-of-view, determine a prominence-display value for the UI element;
• in accordance with a determination that the prominence-display value for the UI element exceeds a prominence threshold, display, via the display, the UI element as the overlay at a second location in the UI associated with the second field-of-view of the device;
• and
• in accordance with a determination that the prominence-display value for the UI element does not exceed the prominence threshold, cease display of the UI element in the UI associated with the second field-of-view of the device.

A non-transitory memory storing one or more programs, which, when executed by one or more processors of a device with one or more environmental sensors and a display, cause the device to:

• display, via the display, a user interface (UI) element as an overlay at a first location in a UI associated with a first field-of-view of the device, wherein the first field-of-view is characterized by a first viewing vector of a physical environment;
• detect a change from the first field-of-view of the device to a second field-of-view of the device, wherein the second field-of-view is characterized by a second viewing vector of the physical environment that is different from the first viewing vector;
• and
• in response to detecting the change from the first field-of-view to the second field-of-view, determine a prominence-display value for the UI element;
• in accordance with a determination that the prominence-display value for the UI element exceeds a prominence threshold, display, via the display, the UI element as the overlay at a second location in the UI associated with the second field-of-view of the device;
• and
• in accordance with a determination that the prominence-display value for the UI element does not exceed the prominence threshold, cease display of the UI element in the UI associated with the second field-of-view of the device.
