Abstract:
The Third Eye for Blind (TEFB) prototype is an innovation created to help the community with vision impairment. The TEFB produced can help the blind community access obstacles at the top of the face level by warning through a buzzer beep signal by detecting a distance of 1 m. Nowadays, especially in Malaysia, the use of a white stick only focuses on obstacles below waist level and the distance according to the length of the stick only. Therefore, TEFB's innovation was specifically developed as an additional tool for the white cane to help the movement of the blind community become easier, smoother and safer. The device consists of a 3D printed frame and is equipped with an obstacle detection and warning system. When the ultrasonic sensor is activated, it can detect obstacles in front within a distance of 1m, then the signal will be received by the Arduino Nano board and then the process of sending the signal directly to the buzzer. The buzzer will produce a beeping sound to alert the user. While the safety feature matched with TEFB is to use a frame sticker that reacts to light, especially when used at night to help people around realize the existence of blind people. In general, this innovation can change the way of life of blind people in living life together with normal people comfortably with smooth movement around. In the future, the use of batteries and sensors will be replaced by smaller and lighter sizes.
