A method includes receiving video data of a user, the video data comprising a first captured image and a second captured image, generating a two-dimensional planar proxy of the user, determining a pose comprising a location and orientation of the two-dimensional planar proxy within a three-dimensional virtual environment, rendering one or more display images for one or more displays of an artificial-reality device based on the two-dimensional planar proxy having the determined pose and at least one of the first and second captured images, displaying the rendered one or more display images using the one or more displays, respectively, determining that a viewing angle of the artificial-reality device relative to the two-dimensional planar proxy exceeds a predetermined maximum threshold, and based on the determination that the viewing angle exceeds the predetermined maximum threshold, ceasing to display the one or more display images.
