Immersion

immersed – To be surrounded by something (i.e. immersed in water)

How do we achieve immersion?

We must give the same input to our 5 senses that we are accustomed to in the real world in order to make the interface to any artificial reality invisible.

Vision

Vision is very sensitive to the location from which we take in the stimulus.

As a result, we need accurate information about the position of the viewer in order to give the correct stimulus to their vision sense.
