Moving with the help of a white cane is an elusive task for the visually challenged unless they create a mental route map with recognizable reference elements. The Smart Cane is intended to provide the visually challenged a better walking experience. The design is incorporated with Bluetooth-enabled obstacle detection module, supported with heat detection and haptic modules. The ultrasonic range finders help in detecting obstacles. The calculated distance is send to an android device via Bluetooth. The user gets voice alerts about the distance through Bluetooth headset. Haptics module is designed to warn the user of moving obstacles with the help of vibratory motors. The goal of this project is to arm its wielder with the functional support of a walking cane without having to possess one physically.
