Augmented Reality: Marker-Based, Image-Based, and Depth-Based
Augmented reality (AR) is a technology that superimposes digital information onto the real world. This digital information can be in the form of images, videos, sounds, and even interactive experiences.
Marker-Based Augmented Reality
Marker-based AR is the most common type of AR and involves using a physical object, such as a QR code or a barcode, to trigger an augmented experience. The physical object acts as a marker that the AR software recognizes and uses to overlay digital information onto the real world.
For example, a customer might use their smartphone to scan a QR code at a store to see product information or to make a purchase.
One of the most well-known examples of marker-based AR is the popular game Pokemon Go. In this game, players use their smartphones to capture virtual creatures called Pokemon by scanning real-world markers such as buildings, monuments, and other landmarks. The game overlaying digital information onto the real world in real-time, making it an immersive and engaging experience for players.
Image-Based Augmented Reality
Image-based AR is similar to marker-based AR, but instead of using a physical object as a trigger, it uses an image or a picture to initiate the augmented experience. This type of AR is commonly used in advertising and marketing campaigns. For example, a company might create an interactive ad that appears when customers scan a specific product or image with their smartphone.
One example of image-based AR is the campaign for the movie The Avengers. To promote the release of the film, Marvel created an interactive ad that appeared when customers scanned specific images of the characters with their smartphones. The ad overlaid digital information onto the real world, allowing customers to see how the characters would look in real life and even interact with them.
Depth-Based Augmented Reality
Depth-based AR is a newer type of AR that uses depth sensors and cameras to create a more immersive experience. Instead of overlaying digital information onto the real world, depth-based AR creates a virtual environment that appears in front of the user’s eyes. This technology is commonly used in gaming and entertainment applications.
One example of depth-based AR is the game Minecraft Earth. In this game, players use their smartphones to build blocks and structures in the real world, creating a virtual environment that appears in front of them. The game uses depth sensors and cameras to create a realistic 3D experience, allowing players to interact with their creations in a way that was not possible before.
The Future of Augmented Reality
AR technology is constantly evolving, and we can expect to see even more innovative applications in the future. As the technology becomes more advanced, it will likely become more integrated into our daily lives. For example, we might see AR used in education to create interactive textbooks or in healthcare to help doctors visualize patient anatomy.
One expert in the field of AR is Dr. Robert Scoble, who has been a pioneer in the industry since its inception. According to Scoble, “AR is going to change everything we do, from how we shop and work to how we learn and communicate.” He predicts that within the next decade, AR will become as commonplace as smartphones and computers are today.
