Development of the Free Mobility System Using General Purpose Equipment for Visually Impaired People

This paper describes the development of a free mobility system in Japan. The Ministry of Land, Infrastructure, Transport and Tourism (MLIT) is trying to develop a free mobility system that is intended to remove any restrictions on the mobility of all people by applying advanced information or communication technologies such as IC tags. IC tags can be installed inside of guide blocks for visually impaired people; the visually impaired user receives auditory information using a guide stick with sensors and a mobile terminal. However, users who do not have a sensor/receiver cannot access the information. In order to develop general purpose equipment for the free mobility of visually-impaired people, the authors conducted experimental studies on the radio marker system that is already available for many types of users. The radio marker equipment radiates electric waves in an area several meters wide and can be accessed by many types of users, including tourists and visually impaired persons. The test results clarify some technical requirements for practical use of this system. The authors describe the fundamental concept and structure of the free mobility system, as well as the results found from experimental studies of the equipment. They conclude that the radio marker system is beneficial, but must be only one component of a free mobility system based on a variety of techniques and tools.
