=== Features of VR ===
VR can be broken down into two main features: '''Immersion'''  and '''Interaction'''. 

'''Immersion:''' 
* The degree to which the user is immersed in a virtual environment depends on the capability of the system and degree to which the application is designed for. Ranging from total immersion, completely engulfing the user in a virtual environment, to non-immersive, with the user aware of their surroundings and accessing the application through a mobile or computer device.


'''Interaction:''' 
* The degree to which a user can alter the virtual world is referred to as interaction.  Full interaction is made possible through VR Systems, such as head mounted goggles, special gloves, and even wired clothing.  In this manner, users can fully interact with the virtual world, viewing it from contrasting angles and even reshaping the environment. On the other end of the spectrum, little to no interaction is available when users see a 3D movie.  Here only one view is possible, with the story unable to be interacted with by users [2].
