Evolution of Technologies for the Convenient Navigations and Utilities for Visually Impaired People

Abstract

The advancement of the various technologies like embedded systems, networking, sensors, actuators and communication can be exploited to design a solutions for the physically challenges people. In this paper an effort is put to survey intensively towards studying the evolution of the innovative ideas proposed for the visually impaired (VI-Ps) people. Many prototype modeling and simulation study is being carried out in this direction. Further, the study outcome provides a strong base to understand the technologies used for designing a utilities and applications for the blind people (BP) and explains about the research trend in this direction.
