Document Summary
Sensation - is the process by which our senses gather information and send it to the brain. Perception sensations and therefore makes sense of everything around us. Each of us creates our own unique perception of the external world. Virtual reality (vr) is an environment that is simulated by a computer. Your mind is fooled into believing that a virtual world (created inside the computer) is actually real. Absolute threshold something becomes noticeable to our senses. It is the softest sound we can hear or the slightest touch we can feel. The absolute threshold is therefore the point at which a stimuli goes from undetectable to detectable to our senses. Difference threshold change needed for us to recognize that a change has occurred. This difference is not absolute, but rather depends on the present level of stimulation. We see with our eyes only a very small part of the entire electromagnetic spectrum.
