Correct Option
(D) All three statements accurately describe tasks accomplished by wearable devices.
- Location identification of a person: Many wearable devices, such as smartwatches and fitness trackers, integrate Global Positioning System (GPS) technology. This enables precise real-time tracking of the wearer's location, which is utilized for navigation, fitness activities, and emergency response systems.
- Sleep monitoring of a person: Wearable fitness trackers are equipped with sensors that monitor physiological parameters like movement, heart rate, and skin temperature during sleep. This data is analyzed to provide insights into sleep quality, duration, and patterns, contributing to overall health management.
- Assisting the hearing impaired person: Specialized wearable devices, including advanced digital hearing aids and cochlear implants, are specifically designed to improve auditory perception for individuals with hearing impairments. These devices process environmental sounds and deliver them in an accessible format.
Incorrect Options
- Option 1 (1 only): This option is incorrect as it excludes the functions of sleep monitoring and assistance for the hearing impaired, both of which are common applications of wearable technology.
- Option 2 (2 and 3 only): This option is incorrect because it omits the capability of location identification, which is a fundamental feature of many modern wearable devices.
- Option 3 (3 only): This option is incorrect as it provides an incomplete representation of the diverse functionalities of wearable technology, overlooking location tracking and sleep monitoring.
