There are many tools and frameworks that help developers in expanding the immersive web with WebAR. For example, AR.js is an open-source library for Augmented Reality on the Web for improved WebAR performance on smartphones that includes marker-based technology (simplified QR-codes) and location-based AR.
Comparison of augmented reality fiducial markers for computer vision. In applications of augmented reality, fiducials help resolve several problems of integration between the real world view and the synthetic images that augment it. [2] Fiducials of known pattern and size can serve as real world anchors of location, orientation and scale.

Computers are responsible for graphics in augmented reality. For camera-based 3D tracking methods, a computer analyzes the sensed visual and other data to synthesize and position virtual objects. With the improvement of technology and computers, augmented reality is going to lead to a drastic change on ones perspective of the real world. [110]
In virtual reality (VR) and augmented reality (AR), a pose tracking system detects the precise pose of head-mounted displays, controllers, other objects or body parts within Euclidean space. Pose tracking is often referred to as 6DOF tracking, for the six degrees of freedom in which the pose is often tracked.
Extended reality (XR) is an umbrella term to refer to augmented reality (AR), mixed reality (MR), and virtual reality (VR). The technology is intended to combine or mirror the physical world with a "digital twin world" able to interact with it, [1] [2] giving users an immersive experience by being in a virtual or augmented environment.
Mediated reality is a proper superset of mixed reality, augmented reality, and virtual reality, as it also includes, for example, diminished reality. [2] Typically, it is the user's visual perception of the environment that is mediated.
The origin R denotes unmodified reality. A continuum across the virtuality axis, V, includes reality augmented with graphics (augmented reality), as well as graphics augmented by reality (augmented virtuality). However, the taxonomy also includes modification of reality or virtuality or any combination of these. The mediality axis denotes changes.
