Abstract: An electronic device displays a representation of a field of view of a camera that includes a view of a three-dimensional space. The representation of the field of view is updated over time based on changes to current visual data detected by at least one of the one or more cameras. Movement of the electronic device moves the field of view of the camera in a first direction. While detecting the movement, the electronic device: updates the representation of the field of view in accordance with the movement; identifies one or more elements in the representation of the field of view that extend along the first direction; and, based at least in part on the determination of the one or more elements, displays, in the representation of the field of view, a guide that extends in the first direction and that corresponds to one of the identified elements.
