Because the computer is physically connected to the human body by its senses and its motor responses.

The physical devices, Which interface to use ?

You have to know that not only Sight interface exist (HMD...), but lots of other, you should have an idea of all the others

What Hardware (interface, computer) ?

What Software (Driver, Toolkit, Programming Language...) ?


NB : By now (and still in the future), human characteristics are higher than what the technical VR device may provide to the user...

Notion of Transparency : with (touch) or without (sight) material medium

Target : try to minimise the delay for the feedback loop : "Action / Perception"

Are the metrology characteristics in adequation with the psychophysics characteristics ?
