Abstract

Sense of vision is one source of vital information to human. It is not excessive if it is being pointed out that the most of information which has been acquired by humans comes from the senses of vision, while the remainder comes from other senses. Thus are, it can be realized that if someone gate some problems with their sense of vision, so their ability to do their activity will be greatly reduced, this is because the information they obtain will be greatly reduced when compared with those with normal vision. In general, the physically blind persons using a white cane or a trained dog to assist the movement and enhance the safety and independence at the time of walking. By having enough information to route that will be passed, persons with visual impairment can be more convenient to navigate in an unknown environment. To solve those problems, we will make a system which can replace and refine the mobility aid which has been existed. This system uses the remaining steps toward an obstacle as the output which expected that it can simplify and make safer the user to navigate in outdoor. On this system calculation error of distance conversion is 4,03 and 4,3 when the system on use to calculate step length. Distance calculation step process takes an average of 5.8 seconds or similar with 4-5 steps while for object detection process takes 1 to 2.5 seconds depending on the type of object being detected. Key Word : Blind, walker, walk sensor, navigation.
