Advanced guide cane for the visually impaired people

This paper focuses on developing a new type of cane for the visually challenged and blind. This advanced guide cane will help the visually challenged person navigate both indoors and outdoors. This cane consists of an obstacle detection system as well as GPS navigation system. The GPS navigation system works only outdoors while the obstacle detector system works everywhere. Both these systems provide a series of audio feedbacks to aid the user. The systems are attached to a walking stick, and are portable and light weight. The advanced guide cane is powered by a rechargeable source and consumes low power. The GPS navigation system is pre-programmed to help the user navigate in the area of his/her choice. The project uses Raspberry Pi, which enables ease of programming and integration of the two systems in our cane.
