4. Virtual Reality Definition
What is virtual reality?
Virtual –
being in essence or effect, but not in fact
Reality –
the state or quality of being real. Something that exists independently of ideas concerning it. Something that constitutes a real or actual thing as distinguished from something that is merely apparent
Virtual Reality
a computer generated ‘immersive’ (or wide field), multi-sensory information program which tracks a user in real time

5. Key Elements of Virtual Reality Experience
Virtual World - content of a given medium
screen play, script, etc.
actors performing the play allows us to experience the virtual world
Immersion – sensation of being in an environment
mental immersion – suspension of disbelief
physical immersion – bodily entering the medium
Related to presence – (mentally immersed) the participant’s sensation of being in the virtual environment (Slater)

6. Key Elements of Virtual Reality Experience
Sensory Feedback – information about the virtual world is presented to the participant’s senses
Visual (most common)
Audio
Touch
Interactivity – the virtual world responds to the user’s actions.

The direct use of VR as a tool in the treatment or assessment of psychological and physical disorders.

11. Augmented Reality Definition
Augmented reality is the overlaying of registered computer generated images over the user's view of the physical world (Azuma, 1997).
Augmented Reality (AR) is a technology which allows computer generated virtual imagery to exactly overlay physical objects in real time (Zhou et al, 2008).
Unlike virtual reality (VR), where the user is completely immersed in a virtual environment, AR allows the user to interact with the virtual images using real objects in a seamless way.
