Description:
KeyBoard is
still the most efficient way of inputting data in to the computer. But ,the
Blind People who cannot recognize the keys in the key pad can sense through
listening.So,the main aim of this
Project is to generate sound for the keys.
This can be done
through ASCII characters which are 256 in number.Here,Providing sound to the
Alpha numeric characters can be generated through the ASCII characters.
Existing System With Limitations:
The
last decade has seen the triumph of the rich graphical desktop, replete with
colourful icons, controls and buttons all around the screen, controlled by the
mouse pointer moving about the screen clicking and dragging. This is not, on
the face of it, a usable environment for blind people, but use it they must.
The first is to use a screen
reader. This is an application that attempts to describe to the blind
user in speech what the graphical user interface is displaying.
The
goal of a screen reader is to make it appear to the user as if the current
application was itself a talking application designed specifically for blind
users. It also means that applications that utilize simple interface components
like menus and text boxes will work best with screen readers.
The
second way for a blind person to use a computer is to take advantage of self-voicing
applications. These are usually applications written specifically for blind
people that provide their output through synthesized or recorded speech. The
obvious advantage is that the application designer can ensure that what is
communicated to the user is exactly what the designer wants communicated -
although this assumes that the designer's conception of what the user needs or
wants to hear is correct!
Proposed System Features :
The
important constraint on the use of computers by blind users is that they rely
on hearing, rather than sight. Why is this such a problem? First, blind users
are constrained into examining one thing at a time in an order not of their own
making - they do not know the structure of things before they explore them.
This is the problem with unfamiliar, rich, new interfaces. Second, blind users
have to listen to a surprising amount of text to give them the same amount of
information as a sighted user might be able to gain in a quick glance. Sighted
users might be able to glance through a large document, scanning the chapter
and paragraph headings for a key word or phrase, because they can see the
headings instantly distinct from the body text and what words they contain. A
blind user, even if they can jump from heading to heading, has to wait for the
slower screen reader to speak the heading: setting it to read as fast as
possible might seem more sensible now.
