We outlined the area of interest and the scope of our work.
The remainder of this paper is organised as follows.
We discuss the research design in Section 2.
And carry out a highlevel classification of devices in Section 3.
The main study is carried out at Sections 4 (technical classification parameters and detailed list of devices) and 5 (potential uses for smart glasses based on suggested target markets).
Finally Section 6 concludes and gives pointers to future work.
