Abstract

There have been numerous accounts of research relating to navigation assistance using vision sensors for those who are visually impaired. The struggle now is to find a solution that is low-powered, easily portable, low-cost, and still effective, which could theoretically be used by visually impaired users in order to improve their quality of life. This paper presents the design and implementation of such a system. The architecture begins with an array of ultrasonic sensors to survey the scene. Following that, distance information is used to provide a variety of distinct audio cues via a Bluetooth headset to its user. Data processing is done on a Raspberry Pi, which acts as the link between the input and output devices. Tests demonstrate that the system is accurate within the threshold radius and functions as a navigational assistant.
