Current Applications of AR

AR technology requires several key components, including a display device, a camera, a processor, and software that can interpret and manipulate the user's environment.

Key Components of AR

AR works by using the camera on a device to capture the user's environment. The software then uses computer vision and machine learning algorithms to identify and track objects in the environment. Once the objects are identified, the software can overlay digital information onto the real world. The user can then interact with the digital information through gestures or voice commands.

Process of AR

There are two main types of AR: marker-based AR and markerless AR. Marker-based AR uses physical markers, such as QR codes or images, to trigger the overlay of digital information. Markerless AR uses computer vision and machine learning to identify and track objects in the environment without the need for physical markers.
