Application of WiFi-based indoor positioning system in handheld directory system

The purpose of this paper is to introduce a handheld indoor directory system which built on WiFi-based positioning techniques. The whole system consists of three modules, namely mobile phone module, Kiosks module, and Website and Database module. The mobile phone module is the main frontend module which installed on users' mobile devices, whereas the Kiosks and website are to provide supports and maintenances to the main module. User can download maps and application from the Kiosks or website. On the other hand, administrator uses the website to manage the database. The proposed system is aimed to provide a new ways of providing indoor floor directory, which offers capabilities to retrieve customizable information, to navigate interactively, to enable location-awareness computing and most importantly the portability of the directory system. Additionally, the proposed system is designated to cater for the needs of visually challenged persons by incorporating screen reader and improved accessibility.
