Literature review (@Martin)

This heading presents an overview of a range of AR/VR applications, based on published literature taken from professional academic journals as well as case-by-case user studies. These articles are read with a particular set of questions in mind so that core data can be extracted and tabulated. These core data and tabulations can form the basis for the introduction to our article, answering our first set of questions: who has done AR/VR, what have they tried, under what circumstances and conditions, and on a longer trajectory, why do AR/VR? What has it added/taken away from experiencing the digital world?
