Lakshmi Narayanan | Bhavna Pnacholi

Abstract: The assistive technology is one of the most basic and important system that helps a persons with a disability to work around his challenges. This paper presents progressive efforts for developing an assistive technology for visually impaired. The system is divided into two parts, first part is the selection part which will either select color or currency according to the users wish and the second part is navigation part. The selection module will help them in color identification of various object around the user and currency denomination recognition for making payment and finally aural output being produced, these processing being done in MATLAB. The navigation part is used for obstacle detection, to help them for free navigation by providing the aural instruction using text to speech converter module.
