問 100
Incorrectア
Creating a storage space that exceeds the capacity of the physically installed memory so that it can be used as main memory describes virtual memory, which has nothing to do with AR.
- イ
正解 Augmented reality (AR) is a technology that superimposes computer-generated information such as text, images, and 3D models onto real scenery like camera footage that captures the real environment. Its defining feature is that it augments reality with information; a typical example is an app in which, when you hold up a smartphone, guidance appears floating above an actual store. Choice イ is exactly this definition itself, so it is correct.
Incorrectウ
Analyzing human speech, digitizing it, and using it for issuing commands or inputting text describes speech recognition, which is different from AR.
Incorrectエ
A science or technology for using computers to imitate intellectual tasks such as human reasoning, learning, and language understanding describes artificial intelligence (AI), which is a different technology from AR.
ここがポイント
- Augmented reality (AR) = a technology that superimposes computer-generated information onto real camera footage and the like, augmenting reality with information. Grasp its difference from VR (virtual reality), which immerses you in a virtual space itself.
- Distinguishing the confusable similar terms: virtual memory (extending main memory), speech recognition (digitizing and inputting speech), and artificial intelligence AI (imitating intellectual tasks) are each separate concepts.
