The challenges of indoor movement analysis

Increasing need for development of location- based services is already pushing its limits. Besides providing current object's position, there exists a demand for the analysis of previous movements in order to extract more meaningful information and knowledge about objects behaviour. The most of the studies considering movement analysis are focused on outdoor environments relying on frequent GPS data recordings. Limitation of current indoor positioning techniques leads to the lack of reliable indoor location-based services and also to the lack of research on analysis and discovery of indoor movement patterns considering semantics of the movement. In this paper, the process of indoor movement analysis is proposed and is given an overview of existing methods, trends and challenges for each step of the process. Several emerging and challenging scientific and technological topics are addressed: (1) ubiquitous positioning especially considering indoor environments ; (2) storing and representing tracking data and heterogeneous environmental data (such as contextual information, environmental setup and time attributes) ; (3) enriching trajectories with semantic and performing exhaustive real- time queries and algorithms for analysis.
