The system is an efficient methodology for aiding the blind and the visually impaired in their navigation. User will be indicated about the nearing obstacle within a closer ambiance. The System detects the nearest Obstacle through a stereoscopic sonar system and sends back vibro-tactile feedback to inform the user about its localization through a beep sound and voice indication for a differentiation between the incorporation of the three sensors. The system also aims at increasing the mobility of visually impaired by offering new sensing abilities. The device is light, portable, but range limited to its own size.
