Augmented Reality (AR) consists of a wide range of technologies that integrate computer-generated content such as images, texts, 3D objects, and videos into the user’s real-world perception.
AR integrates digital content with the surrounding environment in real time.
The term AR was first coined by Thomas Caudell in 1990 to describe the head-mounted displays used by electricians to assemble complex wiring harnesses.
The technology was first applied commercially in 1998 in NFL football games and featured a yellow “first down” line.
AR has traveled a long way since then to become widespread in different applications.
We have several mobile applications, such as Pokemon Go, which seamlessly integrates the real world and virtual elements.
Research has been conducted to adapt the technology to various sectors. Currently, it is being used in education, public safety, healthcare, tourism, gas and oil, and marketing.
AR is going to take on a leading role in providing interactive and simulated environments that facilitate learning, whether in education or any other industry.
In a few years, it can become a mainstream technology in schools and campuses worldwide, fuelled by the wide adoption of mobile technologies.
The value of AR in education was $398.78 million in 2016 and is estimated to reach $8.017 billion by 2021. It is also predicted to grow at a CAGR of 82% by 2021.
AR in Education
The use of AR in education can open up endless possibilities and enable students to learn in a meaningful and fun way.
The implementation of AR in formal education is still in its nascent stage, but it provides significant advantages over traditional teaching methods.
Various studies have compared AR-assisted teaching methods with traditional teaching methods to highlight AR’s probable applications in education.
Until now, students have relied on their textbooks, models, and blackboard diagrams to learn about new things like the earth’s rotation.
Such a process bores the students, and they often do not fully grasp the concept.
Using AR can be a suitable alternative as objects in AR have a 3D appeal and can be manipulated through personal interaction.
Researchers used an AR model to teach undergraduate students about earth-sun relationships related to solstices and axial tilt.
The students who gained the most understanding of the subject moved the virtual image and explored it from different perspectives.
Due to the 3D nature and high control of the AR model, they are able to challenge their misconceptions and form a better understanding.
The researchers concluded that AR technology provides better cognitive access to complex visualizations than traditional teaching methods.
Traditional teaching methods lack the interactivity offered by AR, which can be used to bring mundane subjects to life.
It can be an automobile emerging from a flash card or school textbook or an unfolding wiring diagram from a technical manual- the students get a more realistic way to learn about their environment, manipulate and explore the models, and solve problems.
The interactivity offered by AR enables students to learn by doing, which is a more effective way of retaining knowledge than using eyes, ears, or memory.
The use of AR in education helps students understand the principles of cause and effect, which is not always possible with established teaching methods.
Students can move, change, or manipulate objects using predefined commands.
They can visualize the changes in real life and successfully grasp the concept of cause and effect.
The technology also offers contextual relevance, as educators can use interactive models to explain concepts such as a machine’s working principles.
In the case of books, the students must depend on diagrams and images, leaving room for assumptions.
AR has a significant advantage over traditional teaching in subjects in which the students cannot gain first-hand experience in the real world.
It can help the students better understand concepts and enable them to retain knowledge effectively.
AR has the potential to make learning more engaging and transformational.
