ITPEC IP April 2026 Question 24

Overlaying computer-generated information on live video of the real environment — that is AR (augmented reality).

AR keeps the real surroundings in view, through a smartphone camera or smart glasses, and adds computer-generated images or information aligned with them: directions drawn on the street, a piece of furniture previewed in a real room, labels on a machine. The real world is augmented, not replaced.

Answer (b)

Why not others:

• •(a) — describes virtual memory, which uses auxiliary storage to offer more memory space than the installed main memory
• •(c) — describes speech recognition, which turns the human voice into commands or text
• •(d) — describes AI (artificial intelligence), which imitates inference, learning and language understanding

Key rule: AR adds digital content to the real scene the user still sees; VR replaces that scene with a virtual one.
