近年来，大多数移动的手机都具有行人导航引导功能。尽管全球定位系统（GPS）和先进的信息和通信技术提高了该功能的性能，但据报告，用户有时会感到焦虑，因为位置估计精度低，特别是在城市地区，信息更新延迟。我们的工作的目的是提出行人导航方法，以减少用户的焦虑。我们提出了评估函数来评估各种地标的有效性的基础上的“可识别性”，和“可见性”，和一个路线规划算法，安全和容易的方式找到。通过对不同类型地标的可识别性和可见性的认知实验，构建了估计模型。
In recent years, most of mobile phones have a function of pedestrian navigation guidance. Even though performance of the function has been improved with Global Positioning System (GPS) and high information and communication technologies, it was reported that users sometimes feel anxiety because of low accuracy of the position estimation especially in urban area and delay of information updating. The purpose of our work is to propose pedestrian navigation method to reduce anxiety of users. We propose evaluation functions to estimate various landmarks' effectiveness based on the "recognizability", and "visibility", and a route planning algorism for safe and easy way finding. The estimation model was constructed through several cognitive experiments about recognizability and visibility for different types of landmarks.
