A real-time seamless WYSIWYAS navigation system for smart devices

This paper proposes a WYSIWYAS navigation system for smart devices, which is to be used by a pedestrian in motion. The proposed system is installed as an application for Android smart device with a rear camera. It scans M-CubITS Marker elements arranged on the corridor on every frame of a captured movie in order to estimate its position direction in relation to the destination, and displays a marker indicating the direction of the destination on the screen in real-time. Thus, the system achieves real-time seamless WYSIWYAS navigation. A questionnaire-based survey of subjects of an indoor pedestrian navigation test shows the effectiveness of the proposed system. Furthermore, the answer of the questionnaire showed that the improvement of response performance was call for. Then, we analyzed the performance of the response of the smart device.
