解説

問 19

ア
正解 VR (Virtual Reality) is a technology that blocks the view of the real world with goggles or similar devices and immerses the user as if they had entered a virtual space created by a computer. Option ア is a disaster-prevention training case in which one wears goggles on the head and imagines evacuation methods while watching footage of fire or earthquake (a virtual space) projected inside them. This is itself an immersion into a virtual space isolated from reality, so it is the most appropriate application example of VR.
Incorrectイ
This is a case in which, through the smartphone camera, the furniture one intends to buy is overlaid in real time onto “one's actual room.” It overlays virtual furniture information onto real footage, which is a typical example of AR (Augmented Reality), not VR.
Incorrectウ
This is a case in which pointing the smartphone at a historic site displays images and explanatory information of buildings that existed in the past “overlaid on the real scenery.” Because information is overlaid on real scenery, it is AR (Augmented Reality), not VR.
Incorrectエ
This is a case in which holding the smartphone over an illustrated reference book lets one see videos of organisms overlaid on the pictures or photos in the book. It overlays digital video onto the real book, which is also AR (Augmented Reality), not VR.

ここがポイント

VR (Virtual Reality) is a technology that blocks the view of reality and immerses the user in a virtual space with goggles and the like; AR (Augmented Reality) is a technology that overlays digital information onto real scenery or footage.
Key to telling them apart: if it is an “immersive experience that completely replaces reality,” it is VR; if it “adds information on top of reality through a camera,” it is AR.
