will consider it in more detail. “Marker AR” technology uses fiduciary markers as a point of reference that defines the position, orientation and scale of an AR object in the physical world. If the object is a 3D one, then by rotating the marker the user can view it from 360 degrees. We can argue with the assertion that “fiduciary markers are the truest form of AR because they are used to track objects in the real world” [4, p. 5]. Firstly, a marker is not a form of AR, but merely an important part of a particular AR technology. Secondly, what makes the specifics of AR is not tracking, but embedding digital objects into a real environment.
