解説
問 75
Incorrectア
Software embedded in the ROM of hardware such as a PC or a tablet is a description of firmware, which is unrelated to an activity tracker.
Incorrectイ
A software distribution form that can be used free of charge for a certain period but requires payment for continued use is a description of shareware, which is about software rather than a device.
Incorrectウ
A feature that delivers the activity status and update history of friends and acquaintances on social media is a description of an activity feed (news feed). The name is similar, but it is a software feature, not a wearable device.
- エ
正解 An activity tracker (activity meter) is a device that is equipped with various sensors such as an accelerometer, a heart-rate sensor, and a light sensor, and that, when worn on the body (i.e., used as a wearable), automatically measures and records daily activity such as step count, exercise time, calories burned, and sleep time. Choice エ describes exactly a wearable device that measures steps, exercise time, sleep time, and so on using various built-in sensors, so it matches the definition completely and is the correct answer.
ここがポイント
- Grasp the definition that an activity tracker is a wearable device (activity meter) with various built-in sensors that measures activity such as steps, exercise time, and sleep.
- Distinguish it from confusingly similar terms: firmware (software embedded in ROM), shareware (a distribution form that becomes paid after a trial period), and activity feed (a feature that pushes updates on social networks).
