Abstract: ABSTRACT [0046] To the visually impaired, it is a challenge to move around freely, they need the assistance of someone. Even a normal walking stick can only warn the user when he comes into physical contact with a certain object, and this may leave minimal time to respond. In this regard, this project aims to design and 3D print a Smart Blind Stick which would integrate obstacle detection, vibration-based feedback and navigation assistance in one small but lightweight device. The stick is constructed with a foldable 3D-printed design created with strong yet lightweight materials that are easier to transport and carry to use. The ESP32 microcontroller is the system brain in charge of interpreting the data obtained by ultrasonic sensors to identify the presence of obstacles in front of or below the user. Small vibration motors emit various intensities of vibration, depending upon the distance between the obstacle they will provide clear and intuitive signals without distractions to the user. [0047] To aid navigation and security, the stick also includes a GPS module, so the user can be tracked by Bylnk IOT application. The device uses a Li-ion rechargeable battery with power management system to sustain long operational time. The proposed system comprises ultrasonic obstacle detection, haptics with vibration motors, GPS-based navigation and tracking, and power-efficient functionality into a stick of light weight and ergonomical design. The construction of the body depends on 3D printing. Altogether, the Smart Blind Stick is a relatively cheap, convenient, and simple device that offers more autonomy and mobility to people with disabilities.
