The History of Augmented Reality
Augmented reality (AR) is an emerging technology that superimposes digital information onto the real world. It has gained widespread attention in recent years, thanks to its potential to revolutionize various industries such as entertainment, education, and healthcare.
The concept of augmented reality dates back to the 1960s when Ivan Sutherland created Sketchpad, an early computer graphics program that allowed users to draw and manipulate shapes on a screen. However, it was not until the 1990s that AR technology started taking shape.
In 1992, David Merrill published his book “The Third Dimension: Adventures in Virtual Reality,” which introduced the concept of virtual reality (VR) and augmented reality. Merrill defined VR as an immersive experience where a person is completely surrounded by a simulated environment, while AR involves overlaying digital information onto the real world. He believed that AR had the potential to enhance people’s experiences in the real world by providing them with additional context and information.
In 1994, Tom Ivester and Bill Grossman developed the first AR application called “Virtual Tour of the White House.” This application allowed users to view a virtual tour of the White House while standing in front of the actual building. The success of this application paved the way for further research and development in the field of AR.
In 1997, Marc Andreessen coined the term “augmented reality” when he wrote an article for Wired magazine about his company, Netscape Communications. In the article, he described AR as a technology that overlays digital information onto the real world, making it possible to enhance people’s experiences in the physical world.
The Evolution of Augmented Reality
Since its inception, AR technology has evolved significantly. One of the major milestones in the evolution of AR was the development of smartphones and tablets, which made it possible to deliver AR experiences through mobile devices.
In 2010, Apple introduced ARKit, a software development kit that allowed developers to create AR applications for iOS devices. This led to the creation of numerous AR apps such as Pokemon Go, Snapchat’s filters, and Ikea’s Place app.
Another significant milestone in the evolution of AR was the launch of Google Glass in 2013. Google Glass was a pair of glasses that integrated AR technology, allowing users to view digital information overlayed onto the real world. Although Google Glass was not commercially successful, it sparked widespread interest in AR and paved the way for further research and development in the field.

In recent years, advancements in machine learning and artificial intelligence have enabled AR applications to become more intelligent and interactive. For example, AR apps can now recognize objects in the real world and respond to user input, making them more intuitive and engaging.
The Purpose of Augmented Reality
So, what was the purpose behind the creation of augmented reality? The answer lies in the potential of AR to enhance people’s experiences in the real world by providing them with additional context and information. As Merrill defined it, AR is a technology that allows us to see the world in new ways.
AR has the potential to revolutionize various industries such as entertainment, education, and healthcare.
Case Studies and Personal Experiences
One example of the power of AR is the use of AR in the field of medicine. In 2018, a team of researchers at Stanford University developed an AR application called “EndoAR” that allows surgeons to visualize patient anatomy during procedures. The application uses a combination of machine learning and computer vision to provide surgeons with a real-time visualization of the patient’s internal organs, allowing them to perform surgeries with greater precision and accuracy.
Another example of the power of AR is the use of AR in the field of education. In 2019, a team of researchers at the University of Illinois developed an AR application called “ARCade” that allows students to explore the solar system by overlaying digital information onto textbooks and lesson plans. The application uses augmented reality to bring the solar system to life, allowing students to interact with planets, moons, and other celestial bodies in a more engaging and interactive way.
Research and Experiments
Several studies have shown that AR technology can enhance people’s experiences in the real world by providing them with additional context and information. For example, a study conducted by the University of Maryland found that AR can improve user engagement and retention in e-learning platforms. Another study conducted by the University of British Columbia found that AR can improve memory recall and knowledge retention in students.
Summary
In conclusion, the purpose behind the creation of augmented reality was to enhance people’s experiences in the real world by providing them with additional context and information. AR technology has evolved significantly since its inception, thanks to advancements in machine learning and artificial intelligence. The potential applications of AR are vast and varied, ranging from entertainment to education to healthcare. As AR technology continues to evolve, we can expect to see even more innovative uses of this exciting technology.
