Wearable Device
Wearable Device
A small computer you can wear on your body, like a watch or a pair of glasses.
In Simple Terms
A wearable device is an information device worn directly on the body, such as on the wrist or face. A smartwatch, for example, can track how far you've walked or display messages from your smartphone, just by strapping it to your wrist. There are also glasses-shaped devices that overlay navigation arrows onto the scene right in front of you. The key feature is that wearables let you use digital functions naturally in everyday life, without ever having to pull out a separate device.
Behind the Name
The word "Wearable" in Wearable Device comes from the English word meaning "able to be worn." True to its name, it refers to an information device worn on part of your body, rather than held in your hand. The name captures a shift in how we use technology — from carrying a device to actually wearing it.
Take a Closer Look!
Wearable devices are a category of computers designed to be worn on the body.
As technology advanced, computers evolved from stationary machines to portable ones — and wearables developed as a distinct branch of that progression, built to be attached directly to the body.
Different form factors serve different purposes.
Watch-type devices worn on the wrist and ring-type devices worn on a finger use built-in sensors to record data like step count, sleep quality, and heart rate around the clock, making it easy to track your own health.
Glasses-type devices, on the other hand, are mainly used to supplement what you see — overlaying navigation directions or work instructions directly onto your field of view.
Many wearables connect wirelessly to a smartphone, letting you check notifications right on your wrist or in your line of sight.
The defining advantage of wearable devices is that they let you tap into the power of technology naturally throughout daily life and work, without having to dig your phone out of a bag.
