ABSTRACT: Currently, many researches has been carried to devise the navigation for blind people. Here, we propose an efficient system to aid the visually impaired in their navigation. User will be indicated about the nearing obustruction with closer ambiance. The basic concept behind this system is to detect the nearest hindarence through a stereoscopic sonar system and sends back vibro-tactile feedback to inform the user about its localization through a beep sound provided with voice indication for a differentiation between three sensors imbibed. The proposed system aims in increasing the mobility for visually impaired by offering various sensing abilities. The device is light, portable, but range limited to its own size.
