Quantum space time travel with the implementation of augmented reality and artificial intelligence

Traveling in time and space represents an old dream, which excited the imagination of numerous
writers and artists. Virtual and augmented reality pushes this idea to a new level, and enable to achieve
the first steps in this direction. In this paper, we give an overview of several cultural heritage
applications using virtual and augmented reality. We show the large diversity of applications, the new
possibilities they offer, and finally, their potential in involving the user. Four exemplary applications
"Virtual Stratigraphy", "the virtual Cathedral of Siena", "Arche Guide, an personalized AR-Guide" and
the "AR-Telescope" are briefly presented. Then, the results, success factors as well as limitations are
discussed. We conclude each statement by presenting new results of current research.
