解説
問 14
Incorrectア
This is an example of remote medical care (online consultation) over a network using a PC or tablet device. Neither a PC nor a tablet is a device worn on the body; they are terminals used on a desk or held in the hand, so this does not qualify as an example of a wearable device.
- イ
正解 A wearable device is an information device designed on the premise that it is worn on the body — on the arm, head, clothing, and so on. The smartwatch in choice イ can continuously acquire measurement data such as blood pressure and body temperature while worn on the wrist, and using the changes in that data to detect abnormalities at an early stage is exactly a representative application of a wearable device. Being able to collect vital-sign data on a daily, continuous basis by keeping the device in close contact with the body is a feature unique to wearables that other devices do not have, which is why this is the correct answer.
Incorrectウ
This is an example of managing and sharing the electronic medical records of multiple hospitals on a cloud server — an application of cloud computing or electronic medical records (data sharing). A server is not a device worn on the body and has nothing to do with a wearable device.
Incorrectエ
This is an example of a monitoring (watch-over) system that installs a human-presence sensor on a bed and sends a notification when there is no response for a certain period. The sensor is fixed to the bed (furniture) and is not worn on the body, so this is not a wearable device but an example of monitoring using an IoT sensor.
ここがポイント
- A wearable device is an information device worn on the arm, head, clothing, and so on; smartwatches, smart glasses, and activity trackers are typical examples. Its characteristic is that it can continuously acquire vital-sign data while being worn.
- Distinguish that PCs and tablets (stationary or portable terminals), cloud servers, and fixed-installation human-presence sensors are not worn on the body, so they are not included in wearables.
