Perception is the procedure which people know about objects and situations in the exterior world. Perception occurs in five periods: stimulation, organization, interpretation-evaluation, storage and recall. People studied perception as the necessity to solve a specific problems, occur simply from intellectual fascination with themselves and the earth. It's important to know precisely what kind of perceptual demands can fairly be located on real human senses without compromising safe practices and sanity (Russell & Ward, 1982). The analysis of perception one can identify and appropriate potentially unsafe environment conditions that threaten the senses and impair the capability to make decision. Perception is defined as procedure for one's ultimate connection with the world and requires further control of sensory input.
