Technology is ever changing and ever growing. One of the newest developing
technologies is augmented reality (AR), which can be applied to many different existing
technologies, such as: computers, tablets, and smartphones. AR technology can also be
utilized through wearable components, for example, glasses. Throughout this literature
review on AR the following aspects are discussed at length: research explored,
theoretical foundations, applications in education, challenges, reactions, and
implications. Several different types of AR devices and applications are discussed at
length, and an in-depth analysis is done on several studies that have implemented AR
technology in an educational setting. This review focuses on how AR technology can be
applied, the issues surrounding the use of this technology, viewpoints of those who have
worked with AR applications; it also identifies multiple areas to be explored in future
research.
