[description_short]
Our system consists of six modules, which are briefly described in this document. 
The first module is an interface for the Evaal server, which starts the Evaal trial and requests the next stream of smartphone data in blocks of 0.5 s, and uploads the estimated position. The second modules is a Pedestrian Dead reckoning (PDR) algorithm, which detects steps from the smartphone’s IMU data, and estimates the step length and heading. The third module is a 3D graph of the environment, in which the nodes are accessible positions, and the edges are physically valid (for a human) ways of traveling between the nodes. The fourth module performs BLE fingerprinting, matching new RSS measurements using KNN. The fifth modules is a floor (transition) detection algorithm, which (f)uses barometer, accelerometer, GPS, RSS data. The sixth module is a tracking algorithm which incorporates the graph, PDR, fingerprinting, and floor (transition) detection to estimate the user position.
