| Abstract(in English) | Recently, mobile telecommunication services have been much extended and advanced with the spread of celluar phones. However, researches on practical pedestrian navigation services are limited to outdoor environments. In this paper, we focus on navigation services in indoor environments with complicated structure in comparison with outdoor environments, and propose a route searching method that reflect user's route preference to give the most suitable route to each user. At first, we propose network data structure which is specialized in an indoor environment using a visible graph. Next, we investigate route preference items which should be taken in and show that there is over 70% demand for short-distant routes and more than 80% demand for stairs/escalators/elevators, from elderly persons in particular. In addition to these, there is over 60% demand for crowd-avoiding routes. Therefore, we propose a route searching method that considers "short-distant routes", "stairs/escalators/elevators" and "a congestion situation". To show the effectiveness of the proposal method, we carry out an on-the-spot investigation and show that the most suitable route is output for each user through several types of simulation experiments. |
