There are approximately 300,000 visually impaired persons in Japan. Most of them are old and cannot make appropriate use of their white cane. Therefore, it is imperative to develop some instruments that support the independent activities of the visually impaired. Our objective of this study is a development of the navigation system which can be used in the indoor space (e.g. underground shopping mall, airport, hospital, etc.) and support activities of the visually impaired without help of others. This navigation system can follow a colored guideline that is set on the floor. In this system, a color sensor installed on a white cane senses the colored guideline, and by vibration, the system informs the visually impaired that he/she is walking along the guideline.
