Event Detection for Indoor LBS
While outdoors the position as well as a trajectory is often enough to determine most location events (corners, turns, arrivals at points-of-interest, etc.), inside buildings much more events can become relevant and many applications have to rely on a different technology to find these events. The most prevalent example is that the performance of Wi-Fi localization is pretty good in two-dimensional space, but can have difficulties to determine the right floor. These systems can be supported for example by using a barometer indicating reliably floor changes. This chapter first explains how indoor routes can be explained to a user and which events can be relevant for this explanation. Then, this chapter collects events that have been shown useful for indoor location-based services.
