Wearables are any type of device that can be worn on the body to allow for communication and data exchange with other devices i.e. a smart watch. Wearables are commonly used to track fitness activities such as steps taken and calories burned, monitor heart rate and other biometrics, and communicate with other connected devices like smartphones. Wearables can also be used to support productivity and to access information such as schedules and location aware services. Wearable technology is constantly evolving with cutting edge developments such as virtual reality (VR) headsets and augmented reality (AR) glasses becoming more prevalent. Many major tech companies are investing heavily in wearables, with Apple and Google both embracing this technology.
