While displaying a view of a virtual environment that does not include a visual representation of a first portion of a physical object present in a physical environment in which a user is located, a computer system detects movement of the user in the physical environment. In accordance with a determination that the user is within a threshold distance of the first portion of the physical object which has an extent that is potentially visible to the user based on a field of view of the user for the virtual environment, the computer system changes an appearance of the view of the virtual environment in a manner that indicates a physical characteristic of the first portion of the physical object, without indicating a second portion of the physical object that is potentially visible to the user based on the field of view of the user.
