Description: The physical environment in which augmented reality (AR) experiences take place refers to the real space that interacts with overlaid digital elements. This environment can be any location in the real world, such as a room, street, or park, where users can view and experience digital content through devices like smartphones, tablets, or AR glasses. AR combines the physical world with virtual elements, creating an immersive experience that enhances the perception of the environment. The main characteristics of this environment include the ability to recognize and map physical space, allowing virtual objects to be integrated coherently into reality. Additionally, the physical environment is dynamic, as it can change and adapt to user interactions, providing a personalized and unique experience. The relevance of the physical environment in AR lies in its ability to transform how people interact with information and the world around them, facilitating learning, communication, and entertainment in innovative ways.
History: Augmented reality has its roots in the 1960s when Ivan Sutherland developed the first augmented reality visualization system known as ‘The Sword of Damocles.’ However, it was in the 1990s that the technology began to evolve significantly, with the development of more accessible devices and specialized software. In 1992, Louis Rosenberg created the first functional AR system called ‘Virtual Fixtures,’ used in industrial settings. From 2000 onwards, AR began to gain popularity with the advent of mobile devices and applications that allowed users to experience AR more easily.
Uses: Augmented reality is used in various fields, including education, where it allows students to interact with content in a more visual and hands-on way. In the entertainment sector, it is employed in video games and applications that offer immersive experiences. It is also used in retail, allowing customers to visualize products in their environment before making a purchase. Additionally, AR has applications in medicine, where it is used for training professionals and in surgical procedures.
Examples: A notable example of augmented reality is the Pokémon GO app, which allows players to capture virtual creatures in the real world using their mobile devices. Another example is IKEA Place, an app that allows users to visualize furniture in their homes before purchasing. In the educational field, applications like Google Expeditions enable students to explore historical sites and scientific concepts through AR experiences.
