We follow the five phases of a literature research according to Brocke et al. (2009) and adapted by Feldmann & Gorj (2017) to a linear approach. We finished the first two phases that contains the definition of the review scope and the conceptualisation of the topics. Our research topics are mainly the evaluation methods, which are used for AR applications and which AR applications are introduced in the different papers (according to our classification). We start now with the third phase of our literature research. This phase contains the search for literature in databases with keyword and with a forward- and backward search (Brocke et al., 2009).

We classify our planed literature survey after Cooper (1988). According to this taxonomy our focus are evaluation methods and applications. The goal is to identify which evaluation methods are (not) applied and which classification of applications appear. We want to compare these results to previous survey in this direction. The third characteristic is perspective, we want to have a representative sample of literature. We organize our literature in a methodological and historical matter, we have a look on the year and group them in different topics according to our research goals. The last characteristic describes the intended audience, the survey is addressed to specialized scholars in the field of AR.

We want to classify used evaluation methods based on three layers. The last layer is the most detailed one, it described the exact method, if it is mentioned. Layer two based on (Dünser, Grasset, & Billinghurst, 2008), so that we can compare the results and see if there are any differences or similarities. Layer one is quite rough and subdivide evaluation methods in qualitative, quantitative and mixed methods.

For the research we created a table to collect the results and to have a starting point for the analyse.
