Augmented reality (AR) is a technology that allows a computurized virtual object to be overlaid directed or indirectely in a really environment in a real time (Azuma, 1997; Zhou, Duh & Billinghurst, 2008) and differs from virtual reality (VR) since irt combines the real world with virtual objects, supplementing the reality instead of substituting, making the bridge between virtual and real world in a perfect way (Chang, Morreale & Medicherla, 2010).
