Indoor Positioning for Evaluating an Information System Used in a Hospital Environment

Abstract

This thesis provides an overview of the field of indoor positioning, including technologies, algorithms and methods used in the field. A case study focused on the analysis of tracking data has been performed for this thesis as well. The objective of the case study is to test methods for evaluating an information system used by medical personnel through the analysis of tracking data gathered in a hospital environment. For this, three different models of the personnel's mobility patterns are created for the time periods before and after the system's implementation, and are used to find a difference between these periods. The created models are Markov chains, average weeks of visit counts for each room and average visit durations for each room. These models are shown to uncover differences in the patterns which exist in various aspects of the data. The possibilities for using these results in an expert analysis of the system are examined.
