Abstract
People with visual impairment are part of our society who have the same rights as a citizen which has limited mobility. They need technology to help navigation. Arduino is a microcontroller based technology which can be used to be walking assistance. We hereby propose ‘Bluino’ as walking support for visual impairment students. It is equipped with an ultrasonic sensor HC-SR04 to detect an object within 50 cm, which will trigger the buzzer to produce sound. Bluino is packed into a custom box with a strap placed on the users leg. Three students have evaluated this device. The result shows that the tool can detect an object or obstacle in front of them so they can avoid it. The sensor can detect an object up to 4 meters and 15 degrees measuring angle. They suggested to improve Bluino by simplifying the model, and enabling the sensor to detect holes.
