These devices can include fitness trackers, smartwatches, virtual reality headsets and other types of wearables that incorporate technology into daily activities such as health tracking, communication, entertainment, and productivity. The term "wearable device" generally refers to any electronic gadget that is intended for personal use rather than being used in a fixed location or carried in a bag or pocket.
