Wearable Obstacle Detection System for visually impaired People

This paper presents an obstacle detection system for visually impaired people. User can be alerted of closed obstacles in range while traveling in their environment. The system we propose detects the nearest obstacle via a stereoscopic sonar system and sends back vibro-tactile feedback to inform the user about its localization. The system aims at increasing the mobility of visually impaired people by offering new sensing abilities.
