The aim of this paper is to determine the difference, in augmented reality (AR), between the creation of one single world and the creation of multiple worlds in terms of the “reality” of the augmented world created by the device. This work analyses what kind of relation between subjects and worlds are created by these two different kinds of worlds created from a phenomenological perspective. It will be clear how the production of such an augmented world cannot be solved by mere technical elements, but it has to deal with bigger problems.
