Abstract

Mobility is one prerequisite for carrying out an autonomous and independent life. As mobility impaired pedestrians impose very heterogeneous requirements regarding the calculation of optimized routes and the provision of navigation instructions, currently available navigation systems do not offer sufficient support. The main drawback is due to inadequate map data which is mostly optimized for car navigation. To overcome these limitations, the technique of multimodal annotation of geographical data has been developed for which additional requirements have been gathered by conducting a survey including 88 visually impaired respondents. Within this paper, the results of the survey are presented. Requirements for multimodal annotation are derived and discussed.
