Marker-based systems use a pre-defined image or marker to trigger the AR experience. These systems require the user to point their device’s camera at the marker to activate the AR content. An example of a marker-based system is the Pokémon Go game, where users can catch virtual creatures by pointing their phone’s camera at real-world locations.
Markerless Systems
Markerless systems do not require a pre-defined marker to trigger the AR experience. Instead, they use sensors and GPS technology to determine the user’s location and orientation. This allows for a more natural and seamless AR experience. An example of a markerless system is Google Maps’ augmented reality feature, which overlays directions onto the real world, allowing users to visualize their route without the need for a pre-defined marker.
Conclusion
In conclusion, the evolution of AR from passive to active systems has greatly expanded the possibilities of this technology. Passive systems were the first to be developed and were used primarily in scientific and research applications. Active systems, on the other hand, offer a wider range of applications and can be further classified into marker-based and markerless systems. These systems are designed to superimpose computer-generated information onto the real world, offering users a more natural and seamless AR experience.
