Abstract
In this paper, we describe about a developed navigation system that supports the independent walking of the visually impaired in the indoor space. This system is composed of colored navigation lines, RFID tags and an intelligent white cane. In our system, some colored marking tapes are set on along the walking route. Theses lines are called navigation line. And also RFID tags are set on this line at each landmark point. The intelligent white cane can sense a color of navigation line and receives tag information. In our previous system, it is difficult to detect the direction of a user. Therefore, we developed a new system which can defect user's direction, we will report about this new navigation system.
