Virtual reality typically refers to computer technologies that use virtual reality headsets to generate the realistic images, sounds and other sensations that replicate a real environment or create an imaginary setting. Virtual reality also simulates a user's physical presence in this environment. Virtual reality has been defined as "a realistic and immersive simulation of a three-dimensional 360 degree environment, created using interactive software and hardware, and experienced or controlled by movement of the body" or as an "immersive, interactive experience generated by a computer".

Positive Impacts:

- Can be used for medical simulations, training simulations, architecture etc.

- Gain experiences without the risks that would accompany those experiences in real life.

Negative Impacts:

- Can lead to physical, emotional, and social problems for the user.

- For example; Games, such as Second Life, can be fun escapes from the world we live in. However, if abused they can literally become a second life. The user then cuts his or herself off from the world socially.

- Can cause physical harm to senses such as sight.

- Some virtual realities have been causing problems in marriages and relationships.
