Method for Introducing Wi-Fi-based Area Detection System

The demand for mobility services that are available anywhere is increasing as work styles become increasingly diversified. Location-based services (LBSs) that leverage the user’s present location to provide optimal services are attracting attention as a special class of mobility services, and to achieve indoor LBSs, a variety of techniques for detecting the area in which a user is present have been proposed. Area detection by wireless LAN (Wi-Fi) is particularly attractive since its use eliminates the need for installing a new infrastructure for positioning purposes. However, specialized knowledge has so far been required to judge the detection performance of a system using wireless technology. To eliminate this requirement, we have developed a method for visualizing inter-area detection performance so that non-specialists can judge detection performance of a Wi-Fi-based area detection system. This paper describes the method and shows the results of an evaluation test.
