There are approximately 300,00 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 instrument that support the independent activities of the visually impaired. 2 types of the navigation system were developed for this objective. One is an auto navigation system using GPS. This system uses GPS for positioning of a system user and guides the road information. This system mainly uses in outdoor. Another system enables the visually impaired to walk in dependently in an indoor space. This system can follow a colored navigation line that is set on the floor. In this system, a color sensor installed on a white cane senses the colored navigation line, and by vibration, the system informs the visually impaired that he/she is walking along the navigation line.In GPS navigation system, a voice guidance system that guides road information by artificial voice and a self positioning system that estimates an users position when GPS does not use. Especially, synchronizing method between GPS and a self positioning system were developed. Developed method make possible to obtain an user's position smoothly.In a indoor system, a white cane that detects colored navigation line (called intelligent white cane) is developed. This system was tested by normal subjects. From this experiment, optical beacons and a receiver for these beacons are used in this system. The optical beacons are set on the ceiling and emit the position code as an infrared signal. The receiver receives this signal form the beacons and notifies map information to the user by a pre-recorded voice. And a brand new white cane that can detect 8 or more colored navigation lines is also developed.

日本大约有300,00名视觉障碍者。他们中的大多数是老的，无法适当使用白色的拐杖。因此，必须开发一些支持视力障碍的独立活动的工具。为此目标开发了2种导航系统的类型。一个是使用GPS的自动导航系统。该系统使用GPS来定位系统用户并指导道路信息。该系统主要用于户外。另一个系统使视力障碍可以在室内空间中依赖行驶。该系统可以遵循地板上设置的彩色导航线。在该系统中，安装在白色甘蔗上的颜色传感器感知彩色导航线，并且通过振动，该系统告知视力障碍，他/她正在沿着导航线行走。在GPS导航系统中，GPS导航系统是一种语音指导系统，该系统通过人工声音和自我定位系统估计GPS不使用GPS的自我定位系统来指导道路信息。特别是，开发了GPS和自定位系统之间的同步方法。开发的方法使得可以平稳地获得用户的位置。在室内系统中，开发了检测彩色导航线（称为智能白色甘蔗）的白色拐杖。该系统由正常受试者测试。从该实验中，该系统中使用了这些信标的光信标和接收器。光学信标设置在天花板上，并作为红外信号发射位置代码。接收器接收此信号形成信标，并通过预先录制的语音将MAP信息通知用户。而且，还开发了一个全新的白色甘蔗，可以检测到8个或更多彩色导航线。
