Presence is the feeling of being somewhere else, being in another reality. Presence can be divided into 2 types: Cognitive Presence and Perceptive Presence. Cognitive Presence is the presence of your mind. It can be achieved by watching a compelling film or reading an engaging book. Cognitive Presence is important to an immersive experience of any kind. Perceptive Presence is the presence of your senses. To accomplish Perceptive Presence, your senses, sights, sound, touch and smell, have to be tricked. Perceptive Presence can only be achieved by [[Virtual Reality]] and [[Augmented Reality]].
[[Immersion]] is different from Presence. The former means that you feel surrounded by the virtual world while the latter means that you feel you are within the virtual world. Presence is achieved when the involuntary aspect aspects of human our reptilian corners of our brains are activated. When the user reaches out to grab the virtual apple, becomes unwilling to step off a plank or feel nervous when walking on rooftops.
==Virtual Reality==
Presence is one of the most crucible aspects to a true [[virtual reality]] experience. To have an effective VR, The user has to feel that he or she is within the artificially created world. This is the only way to elicit emotions and involuntary, reflex-like reactions from the user.
