Degradation of the visual system can lead to dramatic reduction of the mobility by limiting the person to his sense of touch and hearing. This paper presents the development of an obstacle detection system for visually impaired people. The user is alerted of closed obstacles in range while traveling in their environment. The system, we proposed, detects obstacle that surrounds the user by using multi-sonar system and sending appropriate vibro-tactile feedback. The system aims at increasing the
