Blind Navigation: Technologies for Visually Impaired

Abstract

Abstracts--Blindness is a condition in which an individual loses the visual recognition. Mobility and self-reliability for the blind has dependably been an issue. A considerable measure has been made to propel advances that enhance blind and partial sighted individual's spatial observation. Many surveys of various technologies of navigation system for visually impaired with their usefulness, design and working according to the requirement of blind people is conducted. Current innovation gives applications to be proficiently appropriated and keep running on versatile and hand-held gadgets, even in cases wherever unique procedures are vital. Electronic travel aids navigation modules, text-to-speech applications, with added advancement in the technology are getting integrated into normal mobile devices. These technologies combined with continuous simple interfaces and methods of collaboration has opened a scope of most recent perspectives for the restoration and being easy to use of people with visual impairment. In general, it can be summarized to those technologies supporting the visually impaired with basic analysis and application development. This can provide better understanding of the technologies and their further analysis for future research.
