Augmented Reality in Education: Interactive Classrooms

The Pew Research Center reports that mobile technology use has more than doubled in the past decade from 35% in 2011 to 81% in 2019, with smartphone use especially prevalent among young Americans — about 96% of people ages 18 to 29 own a smartphone. These trends are creating opportunities for using augmented reality in education.

Augmented reality (AR) is a technology that overlays digital information such as sounds, videos, and graphics on top of the real-world environment. AR is often confused with virtual reality (VR), a technology that creates entirely artificial environments. Together, these technologies are collectively known as extended reality (XR), and they are driving change across industries: IDC reports that the AR/VR market is expected to grow from $16.8 billion in 2019 to $160 billion by 2023.

Industries such as engineering, manufacturing, and space exploration commonly use AR in business applications such as research and development. With the emergence of new technologies and widespread adoption of smartphones, educators are increasingly expected to use AR in the classroom.

What is augmented reality?

Augmented reality superimposes sounds, videos, and graphics onto an existing environment. It uses four main components to superimpose images on current environments: cameras and sensors, processing, projection, and reflection.

Each of these components provides an individual function. For example, cameras and sensors can detect an image’s depth or calculate the distance between two objects before superimposing digital content atop the user’s view. Projection and reflection add virtual information over what a user sees; for example, a method known as projection mapping enables AR apps to digitally overlay video onto any physical surface.

As for processing and transmitting data, limited bandwidth and latency of wireless networks have typically posed challenges to wide-ranging adoption of AR. But thanks to faster wireless connectivity through 5G cellular networks and next generation devices’ improved processing power, opportunities to explore AR’s full potential are expanding.

With these core AR components, educational institutions can incorporate interactive classrooms into their curricula. Why use augmented reality in education? Using AR in the classroom can improve learning by helping educators create interactive classrooms that increase student engagement.

Incorporating AR components into daily work practices can also help businesses solve problems and improve inefficiencies.

Examples of AR use in business

AR has many uses across business functions.

Business presentations: Presenters can face challenges connecting with audiences and delivering messages. Augmented reality engages audiences by making them part of the presentation. For example, instead of asking customers to visualize a light fixture in a certain location, they can use AR to show how it would “really” look.
Prototyping: During the product development stage, designers typically sketch prototypes digitally or on paper and use CAD modeling to produce a facsimile of the end product. Printing 3D prototypes can be expensive, making alterations costly. AR overlays virtual objects onto existing objects, allowing designers to change prototypes without printing a new one with every change.
Research and development (R&D): Companies across industries known for their innovation spend billions of dollars each year on R&D. AR technology means faster and better visualization, improved collaboration, and accelerated time to market, reducing costs.
Training and learning: Presentation is vital to sharing knowledge, and AR can be a handy tool for immersing audiences in their learning. AR applications can have learners move around a room to interact with the content, creating more active educational experiences. This can help them retain knowledge and grasp difficult concepts.

Examples of AR use across industries

AR has many uses across many industries. Here are a few examples:

Engineering: Common applications for AR in engineering include production, training, and support. In the pump industry, AR helps technicians simulate complicated pump installations in water and wastewater operations rather than relying on a repair manual.
Medicine and healthcare: From patient education and physician training to surgical visualization and disease prevention simulations, AR’s benefits for healthcare are clear. For example, one healthcare AR application maps a patient’s body, including the precise locations of veins, enabling healthcare professionals to more accurately draw blood or start an IV ahead of a surgical procedure or during a medical exam.
Retail: AR can enhance interactions between customers and products. A customer browsing through the aisles of a store can point their smartphone toward a product to prompt an AR app to provide relevant information. Retailers like Ikea offer AR-powered apps that enable customers to visualize furniture in their own homes before buying.
Manufacturing: About 2.4 million positions may be unfilled between 2018 and 2028 due to a growing manufacturing skills gap, according to Deloitte. AR can play a pivotal role in closing that gap and addressing complex processes in manufacturing. For example, manufacturing equipment, which often involves dozens of processes for hundreds of individual components, requires regular maintenance. AR can train a workforce to maintain equipment and perform remote equipment diagnostics, increasing manufacturing workforce productivity.
Entertainment: While Pok e mon Go was not the first AR video game, it has been one of the most popular since its 2016 launch, with more than 1 billion downloads as of February 2019. As 5G technology use increases, AR advances will continue to change how people entertain themselves. According to a Deloitte study, millennials and Generation Zers (those around 14 to 36 years old) plan to use 5G to stream more video, play more online games with social features, and immerse themselves in more AR digital worlds.
Space exploration: A Lockheed Martin platform that combines machine learning and augmented reality may soon help humans reach Mars. If a mechanical problem arises on Mars, on-site astronauts might not receive repair instructions from Mission Control on Earth for over 40 minutes. This platform includes an AR visor that displays an overlay of data, such as thermal, gas mixtures, and other vital information, atop a physical space, which can help astronauts find their own timely fixes.
Military and defense: Nothing can replace the intense and grueling physical aspects of training soldiers for combat. But augmented reality is enabling the military to add a layer of training that can help produce better soldiers. These apps improve situational awareness and train users to process information quickly and safely. For example, tactical a ugmented r eality (TAR) provides tactical mapping during a military operation to help soldiers find friends and identify foes.
