Analysis and design of an embedded system to aid the navigation of the visually impaired

This article aims to present the methodologies of development, analysis and system design of an Electronic Bengal, with object-oriented and structured methods, trying to establish the main features of these. From this scenario, several methods of system analysis are available for use. Among the studies conducted to develop the system, using automation techniques, are SART (Structured Analysis Real-Time) and UML (Unified Modeling Language) modelings. Each has its peculiarities, both in the way of diagramming and about the script. The project proposes an electronic device with an embedded system that contains a control algorithm to enable vibration and audio electromechanical transducers. The project is an electronic device based on open-source flexible platforms to assist in the orientation and mobility of the visually impaired during their displacement.
