DESIGN AND DEVELOPMENT OF ASTERISK BASED COMPUTER SERVICES ACCESSING FRAMEWORK FOR THE VISUALLY IMPAIRED

We are today living in age where technology continues to bring about one magical transformation after another into our lives. Especially computers and internet that constitute the cardinal components of the present day technology have so penetrated into our live that they today make up an indispensable part of life. In this paper, we present an Asterisk based framework that is designed particularly to the benefit of the visually challenged people. These people find it difficult to use the conventional computer access devices like the keyboard, the mouse or the monitor as these devices require a good hand-eye co-ordination. Our framework is designed to take DTMF input from the user that serve as commands for execution of different operations on the computer and provide output in the form of voice using speech synthesis. Additionally, our framework provides the benefit of customizing it as per user needs as it is based on the open source platform Asterisk.
