Pedestrian Navigation Reflecting Individual Preference by Fuzzy Measures and Integrals

Abstract

This paper proposes the pedestrian navigation system selecting a route based on users' own preference for routes.The present system consists of a route selection part and a route guidance part.The route selection part chooses the route with the highest subjective satisfaction degree which are estimated by a road evaluation model (REM).The REM is constructed according to individual users' preference, and also applies fuzzy measures and integrals to calculate the subjective satisfaction degrees of a road.The route guidance part gives users instructions with linguistic expressions fitting to users' sensuous feeling of distance (SFD).Experimental results show that the route selected by the present system is preferable to other routes and the REM is individualized appropriately.
