ITPEC IP October 2021 — Question 25 of 100
Virtual reality makes computer-generated objects and spaces feel as though they exist in the real world. Computer graphics, tracking, sound, and displays can create an immersive environment that responds to the user's actions.
Answer (b)
Why not others:
- gradually refining a coarse image describes progressive image display
- replacing physical experiments with numerical models is computer simulation, but not necessarily VR
- combining separately captured people and scenery describes image compositing
Key rule: VR creates an interactive, computer-simulated environment that gives the user a sense of presence within it.
