In VR there are so called 6 DOF (6 degrees of freedom) as users’ activity and gaze are tracked along the x, y and z axis. These 6 degrees practically mean that you may physically move yourself: left, right, forward, backward, up and down and you will get transported to a different world of immersive experiences.
On the other hand, in Augmented Reality, the quality of graphics, higher resolution displays and other metrics can be more rudimentary and basic since you are not viewing content directly, in front of your eyes and in the immersive manner. With Augmented Reality, technical requirements for you to make an app may be less demanding and certainly developers do not have to worry about consumers’ and players’ motion sickness.
Since hardware for both technologies still needs to improve in UX, it will be possible to impress users with AR and VR in foreseeable future.
