Figure 11From: An indoor augmented-reality evacuation system for the Smartphone using personalized PedometryExperiment for Orientation and Heading Estimation. (a) Drifted path (b) Drifted angle. Figure 11(a) shows that the walking path drifted a considerable distance from the actual path, without the use of the mapmatching technique. We conducted an experiment for predicting the walking path angle, when a user changes his direction and the results are shown in Figure 11(b).Back to article page
