The rapid developments in mobile and wireless technology have led to the emergence of different design approaches that respond to user requirements. Among recent emerging technologies, wearable technology appears to be a growing field. Wearable technologies are defined as intelligent devices with a variety of sensors in order to monitor physical movement, which are lightweight, easy to carry, bendable. These devices can be tracked and linked constantly through applications while users are maintaining their daily routines and actions. Due to these features, the use of wearable technology offers many educational opportunities in teaching-learning environments, such as student engagement, contextual learning, recording & sharing, evaluation & feedback, administrative functions and so forth. Besides the educational affordances, there are also some ethical issues. Wearables have major concerns related to privacy, accuracy, intellectual property and accessibility.
