Description: Augmented reality (AR) is a technology that combines elements of the real world with digital information generated by computers, creating an interactive and enriched experience. Through devices such as smartphones, tablets, or specialized headsets, users can see and manipulate virtual objects overlaid in their physical environment. This interaction is achieved using sensors, cameras, and software that detect the environment and add layers of visual, auditory, or tactile information. AR is distinct from virtual reality (VR), which immerses the user in a completely digital environment, as AR enhances the perception of the real world rather than replacing it. The main features of AR include real-time interactivity, integration of contextual information, and customization capabilities, making it a powerful tool in various fields, from education to entertainment and industry. Its relevance lies in its potential to transform the way we interact with information and the environment, facilitating a deeper understanding and a more immersive experience.
History: Augmented reality has its roots in the 1960s when Ivan Sutherland developed the first virtual reality system known as ‘The Sword of Damocles.’ However, the term ‘augmented reality’ was coined by Tom Caudell in 1990 while working at Boeing, aiming to enhance information visualization in manufacturing. Over the years, the technology has significantly evolved, with milestones such as the development of ARToolKit in 1999, which enabled the creation of more accessible AR applications. In the 2010s, the popularization of smartphones and tablets propelled the use of AR in commercial and entertainment applications, highlighted by the release of Pokémon GO in 2016, which brought AR to a mass audience.
Uses: Augmented reality is used in a variety of fields, including education, where it allows students to interact with 3D models of complex concepts. In medicine, it is employed for data visualization in surgeries and medical training. In the retail sector, AR applications allow consumers to virtually try on products before purchasing. Additionally, AR is used in the entertainment industry, in video games and interactive experiences, as well as in advertising, where brands create more engaging and memorable campaigns.
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 smartphones. Another example is IKEA Place, which enables users to visualize furniture in their homes before purchasing. In the educational field, applications like Google Expeditions allow students to explore historical sites and scientific concepts through AR experiences.
