Abstract(in English) This paper describes the studies on improvement measures by using wearable devices and a smartphone and the evaluation experiment of Wi-Fi indoor positioning. The purpose of this study is the improvement positioning accuracy by the integration of information acquired by several smart devices. A conventional and the proposed positioning methods are evaluated by experiments under the same conditions. Although the positioning accuracy of the conventional method is instability, the proposed methods are more stable and better than the conventional method. As a result of conducting a positioning experiment using several wearable devices and a smart phone, it has been shown that positioning accuracy is improved by integrating information on devices with different wearing states.
