An article of manufacture may include a tangible, non-transitory computer-readable storage medium having instructions stored thereon for orienting a display of a portable electronic device configured to control a cargo handling system. The instructions, in response to execution by a processor, cause the processor to perform operations which may comprise identifying an optical label scanned by a camera of the portable electronic device, determining a viewing angle of the camera relative to the optical label, and determining an orientation of the display of the portable electronic device based on the viewing angle of the camera relative to the optical label.
