People rely on three types of cues to determine which way is up: visual, gravity & body direction. Sensation is the stimulation of sense organs: involves the absorption of energy, such as light or sound waves, by sensory organs like the ears and eyes. Perception is the selection, organization, and interpretation of sensory input: involves organizing and translating sensory input into something meaningful, such as a face.
