A wearable is a small electronic device that can be worn on the body. The most common type of wearable is a fitness tracker, which is used to track steps taken, heart rate, and other health data. Other types of wearables include smartwatches, which are used to view notifications and control smart devices; and virtual reality headsets, which are used to immerse oneself in a digital environment.
Some of the emerging trends in wearables include the use of smart fabrics, the integration of sensors into clothing, and the use of biometric data for fitness tracking.
