‘Human Computer Interfacing’ PREMBLE: This paper was mainly intended for the blind people who could not make use of computer efficienly, who could just interact with computer only through the braille display or the knowledge of typing. In order to facilitate them to constrict the vulnerabilities that peep out through, while engaging with system security and data security (giving wrong passwords) and other security threaten applications our paper could serve as an alternative. ABSTRACT: The Acronym for jaws is “Job Access with Speech” .The first part of this paper introduces the necessity of refreshable Braille display, device which rests on to the keyboard by means of raising dots through holes in the flat .The second part focuses …show more content…

It gathers the content of the screen from the operating system converts it into Braille characters and sends data to the display. The Screen readers for graphical operation systems are especially complex, because graphical elements like windows and slide bars have to be interpreted and described in text form. A new development, called the rotating wheel Braille display, was Introduced in 2000 by the National Institute of Standards and Technology And It is still in the process of commercialization. The Braille dots are put on the edge of a spinning wheel, which allows the blind user to read continuously with a stationary finger while the wheel spins at a selected speed. The Braille dots are set in the simple scanning style fashion as the dots on the wheel spins past a stationary actuator that sets the Braille characters. As the result, manufacturing complexity is greatly reduced and rotating wheel Braille display will be much more inexpensive than traditional Braille …show more content…

The critical issues for current speech synthesizers concerns trade-offs among the conflicting demands of maximizing the quality of speech, while minimizing memory space, algorithmic complexity, and computation speed. The text might be entered by keyboard or optical character recognition or obtained from a stored database. Speech synthesizers then convert the text into a sequence of speech units by lexical access routines. Using large speech units such as phrases and sentences can give high quality output speech but requires much more memory. A block diagram of the steps in speech synthesis is shown
