I am afraid of the speed of this technology. Indeed Virtual Reality is one of the most promising stuff which gives you incredible and unbelievable results. No doubt credit always goes to the developers and all the team behind that project. Arianna App is also one of such type of projects which can be revolutionary one. I am so happy that humanity is still alive and people are working for disabled people which is really appreciable. Great hunt of the day:

Some special labels, such as QR codes, could also be deployed along the path for giving additional information, such as audio-guides.

I really wanna give a big Salute to the Makers of this awesome project and also thanks to the @leoumesh for searching a valuable stuff. Keep it up man.
