A perceptual system is a computer designed to make inferences about properties of a physical environment based on scenes.^[1] In this context, a scene is defined as information that can flow from a physical environment into the computer via sensory transduction.

Perceptual systems can be biological or artificial. By definition, a perceptual system must receive input from sensory organs.

Examples of perceptual systems include

The human visual system
The human auditory system
A bat's sonar/echolocation system
A man-made light intensity meter
A man-made motion detector

Research in the field of perceptual systems focuses on computational aspects of perception. For this reason, there is significant overlap with neuroscience, sensor design, natural scene statistics^[2]^[3], and computer science.
