Abstract

A computer system displays virtual objects overlaid on a view of a physical environment as a virtual effect. The computer system displays respective animated movements of the virtual objects over the view of the physical environment, wherein the respective animated movements are constrained in accordance with a direction of simulated gravity associated with the view of the physical environment. If current positions of virtual objects during the respective animated movement of the virtual objects corresponds to different surfaces at different heights detected in the view of the physical environment, the computer constrains the respective animated movements of the virtual objects in accordance with the different surfaces detected in the view of the physical environment.
