Abstract(in English) | In this paper, we propose a system that improves both estimation accuracy by combining activity recognition and indoor localization, and evaluate by experiment. The likelihood is the probability independently obtained from the position determination subsystem and the activity recognition subsystem, and the posterior probability is calculated from the prior probability distribution which is a certain location acting. In addition, in order to reduce the cost of site survey, we used the AP data acquired while walking, and examined the effects of radio map creation and walking direction. Experimental results showed that when fusion of activity recognition and indoor localization improves the performance of both. In addition, the localization performance of the radio map created by walking is influenced by the walking direction, and the activity recognition performance is not affected by the walking direction. |
