Imagine being in front of a ruined building, looking at it through the camera of your smartphone and seeing information on the screen about the building or seeing it perfectly restored. In this way we are literally “augmenting our reality”, i.e. observing the real world and adding layers of digital information through different kinds of stimuli.
This is just an example, but thanks to augmented reality we can do a lot more. The objective of AR is to superimpose a virtual world onto the physical one, allowing real-time interaction between the two through sensorial input, mainly visual or tactile. All of this thanks to the use of digital devices such as smartphone tablets or visors specifically designed for AR.
