Augmented reality has been a subject of increasing interest for the past few decades. In a 2012 study, Berryman indicates that the term "augmented reality" was coined by Tom Caudell and David Mizell in 1990, but that the concept of augmented reality is older .
In a 2014 article, Mekni and Lemieux define augmented reality as a technology that combines the characteristics of reality and virtuality in order to produce an interactive 3D product presentation .
The four main components that any augmented reality setting requires are: displays, input devices, tracking, and computers. However, the way these components are assembled can vary depending on the needs of the application.
Unlike virtual reality, augmented reality does not immerse the user in a virtual environment, but adds connectivity to the real world by superimposing virtual objects on it .
In an article in 2019, Tim Perdue notes that augmented reality can be applied to various types of industries , including the military or medical sector, shipping, tourism, advertising and promotion. In the military sector, augmented reality is used to facilitate soldiers' maneuvers by allowing them to be viewed quickly in order to avoid any distraction. In the medical sector, augmented reality techniques allow surgical procedures to be carried out in a controlled environment. Thus, surgeons benefit from increased sensory perception, which limits the risks associated with operations.
In navigation systems, augmented reality provides a simplified driving experience and provides real-time information. Augmented reality has also enabled innovations in the field of tourism by replacing tourist guides. Tourists can now browse historic sites by viewing the specifics of the place on their smartphones.
