Abstract

People with visual disabilities or blind people often experience difficulties in their daily activities. Especially if they go to a place they have never visited before. They can get lost on their way back home. This study aims to create an obstacle detection tool as a guide and as a tracker for the position of the blind when they are lost. Apart from that, how to make a tool to help the blind without disturbing their movement activities. The methodology used in this study is designing a tool with an infrared sensor as a detector and ATmega 328P as a microcontroller equipped with a Global Positioning Sistem (GPS) model. The advantages of this obstacle detection tool design are that it is in the form of a box that is attached to the chest (chest strap) weighing ± 500 grams. The indicator of an obstacle is in the form of a vibration felt in the chest. The location of the blind person's position utilizes GPS facilities that are interconnected with Google Maps on a smartphone. The measurement results show that the detection distance to obstacles is 50 cm in a perpendicular direction to the tool. The delay of the short message signal (SMS) received by the smartphone is between 1 and 2 seconds. The furthest location that GPS can still detect was at latitude -6.17519 and longitude 106.50083. Based on the distance mapped by Google Maps, it is equivalent to 13 km from the measurement point to the blind person's location.
