There are different types of augmented reality navigation systems, and they vary according to the technology used and the purpose of the system. Here are some of the most common types:

Marker-based AR

This type of AR navigation system uses a predefined marker or image to trigger the AR experience. The system detects the marker using a camera and overlays the virtual information on top of the real-world view. This type of AR navigation system is commonly used in museums, tourist attractions, and other places where visitors need additional information.

Markerless AR

This type of AR navigation system does not require a marker or predefined image. Instead, it uses sensor data, such as GPS or accelerometer, to detect the user's location and orientation. The system then overlays the virtual information on top of the real-world view. This type of AR navigation system is commonly used in outdoor navigation, such as hiking or cycling.

Projection-based AR

This type of AR navigation system projects virtual information onto real-world surfaces, such as walls or floors. The system uses a projector and a camera to detect the user's movements and adjust the projection accordingly. This type of AR navigation system is commonly used in indoor navigation, such as in hospitals or airports.

Wearable AR

This type of AR navigation system uses wearable devices, such as smart glasses or headsets, to display virtual information in front of the user's eyes. The system uses sensors and cameras to detect the user's location and orientation and adjust the display accordingly. This type of AR navigation system is commonly used in industrial or medical applications.

Each type of AR navigation system has its advantages and disadvantages, and the choice of system depends on the specific application and user requirements.
