In Egypt, 800,000 suffer from blindness. It is estimated by 2020, all blind-related numbers will double. According to several studies, the most urgent and important problem for them is their physical mobility and the autonomous walking.
The aim of this project is to provide an integrated electronic travel aid for blindís mobility, with a low cost, that covers the blindís requirements to do what it needs to navigate, move and travel independently and safely.
The introduced electronic travel aid is an integrated assistive belt consists of three major parts: dealing with the obstacles from different aspects and guiding according to them, localization system for navigation, and emergency SMS in case of getting lost or needing help. All the given feedbacks are hearable or tactile to achieve the user requirements according to the nature of the blindís senses.
