There are variety of devices available on the market for the construction of an AR physical structure to use one or
another technological approach. Year by year manufacturers predict the perspectives of AR devices and support new
equipment versions with better characteristics and performance. This is leading our society to use these technologies
in almost all fields and disciplines. It is not possible anymore to clearly distinguish use cases by field. If years ago
AR was a technology for industrial training and design, military and entertainment; then now AR technologies are
used everywhere in new and different manners. It is rather appropriate do classify use cases in types of usage based
on aim and result, not discipline (see Fig. 3).
