Virtual Reality vs Augmented Reality

Virtual Reality
- Virtual reality involves the creation of a computer-generated world that a person can interact with in such a way that he or she believes that the virtual world is real. Usually this is achieved when the wearing of a helmet, courts the senses to immerse the user.
Augmented Reality
- Augmented reality, however, is a meeting of virtual reality and real life, as a computer image melds with real-life images to create a composite for the user to interact with. The ultimate goal of augmented reality is the user's inability to distinguish the fabricated from the real.
Difference in Immersion
- While the two concepts are related as far as immersing the user (albeit in different degrees of fabricated worlds), virtual reality completely isolates the user from the real world while augmented reality requires a user to continue to be in touch with the surrounding world.
Issues with Virtual Reality
- For virtual reality to be convincing to the user, a program requires the construction of an entire world to painstaking detail, which can be expensive to produce at the risk of seeming false.
Issues with Augmented Reality
- Augmented reality faces a similar problem in convincing the user. Computer-generated images must appear photo-realistic in order to seamlessly integrate with the real world images. However, augmented reality also faces another problem: because the computer augmentation needs to occur in real time, the composite image would need to be constantly accurate, as any lag or inaccuracy will disrupt the experience.
