Exploring the 3 Types of Augmented Reality: Marker-Based, Markerless, and Projection-Based
Augmented Reality (AR) is a technology that overlays digital information onto real-world surroundings in real-time. It provides users with an enriched experience and has a wide range of applications in various industries, including healthcare, advertising, education, and entertainment. AR technology is broadly categorized into three types: Marker-Based, Markerless, and Projection-Based.
Marker-Based Augmented Reality
Marker-Based AR is also known as image recognition AR. It requires a camera-enabled device and a specific image (i.e., marker) to trigger the digital overlay. The digital overlay is pre-programmed and appears on the camera screen once the image is recognized. This type of AR is commonly used in gaming, advertising, and interactive product demonstrations.
Markerless Augmented Reality
Markerless AR, or location-based AR, does not require a specific image or marker to trigger the digital overlay and superimposes graphics onto the real-world surroundings. Instead, it uses GPS, sensors, and machine learning algorithms to determine location and orientation to augment the real world. This type of AR is used in navigation, tourism, and social media platforms, among others.
Projection-Based Augmented Reality
Projection-Based AR, also known as spatial AR, is a type of AR that projects digital images onto real-world objects. It requires a projection device, such as a projector, to display the digital overlays. Unlike the previous types of AR, the projected digital overlay appears physically on the real object or surface. This type of AR is used in interactive advertising, art installations, and entertainment.
Conclusion
Augmented Reality has transformed the way we interact with the world around us. With the three types of AR – Marker-Based, Markerless, and Projection-Based – we get to experience the world in a whole new way. The future of AR is limitless, and as the technology continues to evolve, we can only expect more innovative and exciting applications for AR in various industries.
