Which of the following is the most appropriate example of a use of a wearable device?
Explanation
Measuring blood pressure and body temperature with a smartwatch to detect abnormalities early — the only option where the device is worn on the body.
A wearable device is a computer worn on the body, such as a smartwatch, fitness band or smart glasses. Its sensors measure the wearer continuously during daily life, and the data can be sent to a smartphone or the cloud so that changes in health are noticed early.
Answer (b)
Why not others:
- •(a) — receiving a doctor's diagnosis over a network on a PC or tablet is telemedicine; the devices are not worn
- •(c) — sharing electronic patient records from several hospitals in the cloud is a cloud service for medical information
- •(d) — a human presence sensor installed in a bed is an IoT sensor fixed in the surroundings, not a device worn by the person
Key rule: Wearable is about where the device is: on the body, measuring the wearer wherever they go. Sensors fixed in rooms or beds are IoT devices but not wearables.
