Smart Assistance Spots for the Blind or Visually Impaired People

Abstract

This paper describes the design and development of a system whose main purpose is to guide blind or visually impaired people through different environments in a city. The system consists in a mobile application that orients the user with audio messages and a set of geolocated electronic devices distributed at strategic points of an urban center. These electronic devices send environment information to the mobile app through wireless communication, providing accessibility and simplicity. A fully functional prototype was implemented, with a mobile application developed for Android and devices created on the Arduino platform.
