摘要：The proposed work presents a navigation system, which detects the obstacles and also guide to visuallyimpaired people about appropriate path. The system we propose detects the obstacle via an infrared baseddetecting system and sends back vibro-tactile or sound (buzzer) feedback to inform the user about itsposition. The most common method of obstacle detection, used by blind people is the walking stick. Thelimitation of walking stick is that, it does not provide protection near to head area. A sensor module is fixedon a light weight cap allowing the user to obtain the information about obstacles (near to head area) andalso about correct path on which the user should move. When the user uses this system with cane, he isfully protected about obstacles and can navigate freely into the environment.
