Augmented reality (AR) uses various technologies, including computer vision, simultaneous localization and mapping (SLAM), depth tracking, and sensor fusion, to analyze and understand the environment. This enables AR applications to position and interact with digital objects in the real world accurately. For example, through an AR app, a user can see a virtual object placed on a table or interact with a digital character in the real-world setting.
A Brief History of Augmented Reality
While Augmented reality (AR) may seem like a recent phenomenon, its origins can be traced back to the 1960s. One of the first known instances of Augmented reality (AR) was created by Ivan Sutherland, who developed a rudimentary system called the “Sword of Damocles” in 1968. This system used a head-mounted display (HMD) to project simple graphics onto the user’s field of vision.
However, it wasn’t until the 1990s that AR began to gain more attention in both academia and industry. In 1992, Tom Caudell coined the term “augmented reality” to describe a system that helped workers at Boeing’s factory visualize wiring diagrams in a real-world environment. This was a significant step in making AR a practical technology for industrial applications.
In the 2000s, AR began to gain momentum with the development of mobile applications and smartphones. The advent of smartphones equipped with GPS, cameras, and accelerometers allowed AR applications to become more mainstream. The launch of Apple’s ARKit and Google’s ARCore in the 2010s marked the beginning of the mobile AR revolution, giving developers tools to create more sophisticated and interactive AR experiences.
