| Abstract | Although, Global Positioning System (GPS) has ability to specify a position and navigate users to desired locations, it has limitations, when it is applied in an indoor conditions such as building, or underground due to the signal penetration of satellites. Also, the current indoor technologies like WiFi does not practically respond the answer in terms of the accuracy, and process of creating the radio map. Therefore, this study proposes the solutions, which comprises of main three objectives; to investigate the optimum number of scanned points, to develop a hybrid system between WiFi and NFC technologies, which has the additional turn-by-turn function viewed on Augmented Reality called IndoorNavi application, and to evaluate a standalone WiFi system with the IndoorNavi. As a result, we found that the number of scanned point can be reduced to 80 points from 160 points but still keep the accuracy, the IndoorNavi has been developed based on Android platform, which has multi functions such as specifying the location and routing to the desired destinations, turn-by-turn AR view, and tracking the users. For the result of the evaluation, the hybrid system has ability to increase the accuracy to 83 % in ideal condition as well as the number of getting out of the route and the time of user arrival have become less than using only WiFi. |
