One of the qualities of an intelligent system is perception ability. It refers to
the ability that provides information to agents using sensors. Human beings have five
main sensory organs, which include: sense organ of hearing, vision, tasting, feeling,
and smelling. Therefore, to act like man, which means to possess the attributes of an
intelligent system, the system must have the ability to perceive the outside world it
inhabits using the five sensors, ear, eye, tongue, skin, and nose. The following sensors
have been developed in artificial agents, which they share with human sense organs:
vision, hearing, and touch. This chapter focuses on these three sensors of an artificial
agent.
