Blindness is a lack of vision. It may also refer to a loss of vision that cannot be corrected with glasses or contact lenses. Among numerous forms of disability, blindness is one of the most suffering that can strike people of all ages and it affects the victim’s life. In 2010, the Welfare Department accounted for 64,000 blind people registered in Malaysia and the estimated number of blind was 4 to 5 times higher. This indicates that the percentage of the blindness person in Malaysia is quite high. In the process of Blind Aid Tool (BAT) fabrication, there are two main parts involved, the internal system and external parts. The internal system contains ultrasonic sensor, micro-controller board (ARDUINO Pro Mini 5), and DC vibrator motor that produce vibration while the external parts are the product casing. The system has one ultrasonic sensor which is to detect obstacles in the user path. The sensors will detect the obstacle and resolve the distance between the obstacle and the user. The output of the sensor will be sent to the micro-controller, The micro-controller receives the output signal from the sensors and processes them. If the output signal is within the programmed three feet range then the micro-controller will activate the indicators. The casing design is created using CAD software (CATIA) and fabrication is using Fused Deposition Modeling (FDM) 3D printer. In conclusion, this Blind Aid Tool can help blind people to move to unfamiliar area without human guidance.
