What is a key feature of wearable technology?

Wearable technology is designed to be worn on the body. Which of the following best describes a key feature of wearable technology?

A It must be connected to the internet at all times to work.

B It is designed to be worn and often tracks health or activity data.

C It is always a large device that cannot be carried easily.

D It only works when plugged into a computer.

💡 Hint

Think about devices like smartwatches or fitness bands.

Wearable technology is small devices worn on the body that often track health or activity data, like steps or heart rate.

❓ Comparison

intermediate

How does wearable technology differ from traditional computers?

Which option best explains how wearable technology differs from traditional desktop or laptop computers?

A Wearables are larger and less portable than traditional computers.

B Wearables always have a physical keyboard, unlike traditional computers.

C Wearables cannot connect to the internet, while traditional computers can.

D Wearables are designed to be worn and provide continuous data collection, unlike traditional computers.

💡 Hint

Consider portability and data collection features.

Wearables are small devices worn on the body and often collect data continuously, unlike traditional computers which are larger and not worn.

Trace the data flow in a wearable fitness tracker

Consider a wearable fitness tracker that measures steps and heart rate. Which sequence correctly shows the flow of data from measurement to user display?

A 1,2,3,4

B 2,1,3,4

C 1,3,2,4

D 3,1,2,4

💡 Hint

Think about the order from sensing to displaying data.

The sensors first detect data, then the processor handles it, stores it temporarily, and finally the data is displayed or synced.

❓ identification

advanced

Identify the main privacy concern with wearable technology

Wearable devices collect personal data continuously. What is the main privacy concern related to this?

A Personal data could be accessed or shared without permission.

B The devices use too much battery power.

C Wearables are too expensive for most people.

D The devices are difficult to wear comfortably.

💡 Hint

Think about data security and user control.

The main privacy concern is that personal data collected by wearables could be accessed or shared without the user's permission, risking privacy.

🚀 Application

expert

Which wearable technology feature best supports accessibility?

A wearable device helps a user with hearing loss by converting sounds into vibrations. Which feature best describes this?

A GPS tracking for location services

B Battery saving mode to extend usage

C Haptic feedback to provide sensory alerts

D Data synchronization with cloud storage

💡 Hint

Think about how the device communicates alerts without sound.

Haptic feedback uses vibrations to alert users, which is helpful for those with hearing impairments.
