In the context of mobile devices, location based services play a central role. The determination of the necessary geolocation is usually done via GPS, which is only applicable outdoors - as an indoor alternative, a number of IPS (indoor positioning systems) were developed, which depend on specific hard- and software on site or on the device respectively, and do not deliver the necessary accuracy.
The goal of this bachelor project was to develop a navigation- and information system for subways (UNIS), which is independent of before mentioned hard- and software, and is able to provide appropriate information with an adequate degree of spatial and temporal accuracy.
To achieve this, the data from a mobile device's accelerometer and barometer is utilized, as well as the fact that a subway trip occurs as a one-dimensional, directed movement with discrete breakpoints, a characteristic elevation- and acceleration profile, and the fact that subways usually travel corresponding to a schedule. UNIS is to be instantiated and tested in Munich and Vienna.
