解説
問 25
- ア
正解 The correct answer is “ア AR”. AR (augmented reality) is a technology that superimposes computer-generated digital information such as text and images on top of real-world scenery or video. In this question, when a smartphone is pointed at a historic site, images of buildings that once stood there and their descriptive information are displayed superimposed on the real scenery that is actually being viewed. This is exactly “augmenting” reality with information, so AR is the most appropriate term to describe the mechanism used.
Incorrectイ
GUI (graphical user interface) is an operation-screen method that displays icons, buttons, and the like as graphics on the screen, allowing intuitive operation by mouse or touch. It is not a technology that superimposes digital information on real-world scenery, so it is incorrect.
Incorrectウ
VR (virtual reality) is a technology that immerses the user in a virtual space created by a computer. It shuts out the real-world scenery and shows only the virtual world, which is the opposite idea from superimposing information on the real scenery in this question, so it is incorrect.
Incorrectエ
A metaverse is a three-dimensional virtual space service built on the internet, referring to a virtual world where users participate and interact through avatars. It is not a mechanism that superimposes information onto real-world scenery, so it is incorrect.
ここがポイント
- AR (augmented reality) superimposes digital information onto real-world video, while VR (virtual reality) immerses the user in a virtual space. Distinguish them by whether it overlays onto reality or enters the virtual world.
- GUI is an operation-screen method and a metaverse is a virtual space service; neither is the same as superimposing information onto real-world scenery, so keep this distinction in mind.
