During the last decade, research in indoor localization and navigation has focused on techniques, protocols, and algorithms. The first International Conference on Indoor Positioning and Indoor Navigation (IPIN) was held in 2010. Since then, this annual conference showed the progress of research and technology. The variations of evaluation methods are significant in this field: they range from none, to extensive simulations, and real-world experiments under non-lab conditions. We look at the articles published in the proceedings of IPIN by IEEE Xplore from 2010 to 2014, and analyze the development of evaluation methods. We categorized 183 randomly selected papers, in respect to five different aspects. Namely: (1) the underlying system/technology in use, (2) the evaluation method for the proposed technique, (3) the method of ground truth data gathering, (4) the applied metrics, and (5) whether the authors establish a baseline for their work.
