Interactive Classrooms: 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. 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 ref...
