Sensor Based Assistance System for Visually Impaired
Journal Title: INTERNATIONAL JOURNAL OF ENGINEERING TRENDS AND TECHNOLOGY - Year 2013, Vol 4, Issue 10
Abstract
This paper is focussed to develop an electronic navigation system for visually impaired, that makes use of sensors for obstacle detection. People who are visually impaired struggle every day in performing actions that can be as simple as moving from one point to another without falling down or knocking against obstacles. An Electronic Travel Aid (ETA) is a form of assistive technology having the purpose of enhancing mobility for the blind and visually impaired (VI) pedestrian. Assistive devices designed to aid visually impaired people need to deal with two different issues: at first they need to capture contextual information (distance of an obstacle, position of the sensors, environment around the user), followed by their need to communicate to the user with those observed information. Sensors are deployed for obstacle detection. The real time signal reflected from the obstacles is collected by the sensor and Arduino Board processes the signal. Based on the processed data, appropriate decision is taken by the microcontroller in it. Accordingly a relevant message is invoked from the flash memory. Further this can be extended to communicate or deliver the decision to the subject via earphones.
