A Hybrid System to Assist Visually Impaired People

Blindness is one of the serious problems that is affecting the vast majority of people globally. Traditionally, the affected ones use white cane or a dog to assist them. However, they still have a lot of disadvantages. So, the aim of this paper is to develop a system to assist visually impaired people which acts as a navigation and obstacle/object recognition system. The system discussed in this paper is a hybrid guidance system that uses traditional stick and sensors (camera and ultrasonic) for coping in indoor and outdoor environments. The user is assisted without any human guidance by using a design with sensors and auditory feedback.
