On the M-CubITS Pedestrian WYSIWYAS Navigation Using Tile Carpets

摘要

This paper proposes the M-CubITS pedestrian WYSIWYAS navigation system for intuitive guidance using tile carpets that are wide spread in buildings. We adopt tile carpets instead of textured paving blocks that we have used in our previous studies of the M-CubITS pedestrian WYSIWYAS navigation system because of their wide spread use. In addition, since for setting up only exchange tile carpets are required and wide spread mobile phone devices can be used as users'' devices, realization costs are extremely low. This paper discusses follows: how to use the tile carpets as M-CubITS elements, how to design Human-Machine Interface (HMI) of users'' terminals, and how to implement the navigation software on the general purpose mobile phone devices. We carry out experiments under 25 destinations scale environments in two buildings using 660 tile carpets and the experimental result shows that the average processing success rate on users'' terminals is approximately 59%, furthermore according to the result of questionnaire about usability tests, such usability indexes as "operationality", "visibility", "feelings", and "usefulness" are more than 80%. Consequently, we confirm the effectiveness Of the M-CubITS pedestrian WYSIWYAS navigation system using tile carpets suitable for indoor environments.
