The document proposes a lightweight browser extension for Google Chrome that would aid accessibility by allowing users to zoom in on web pages, restyle pages for easier reading, and select text to have it spoken aloud. The extension is divided into three main parts - a zoom function, a readability styling function, and a text-to-speech function. It would combine multiple accessibility features into a single browser extension to provide an enhanced experience for users with vision or hearing impairments.

2. Lots of people have problems viewing web
content due to health problems that affect
vision and hearing
Accessibility options come to provide a suitable
experience so that people can experience web
pages without problems
Hearing can be aided by using visual
enhancements, and vision can be aided by
audio enhancements

3. Obviously, a good solution would be to provide
some sort of application which would combine
audio and visual enhancements
A good idea would be to create a small
lightweight web browser extension
Some basic principles that need to be followed:
Flawless
experience
Enhance visual
clarity
Aid hearing

4. I propose a lightweight browser extension for
Google Chrome (because of how easy it is to
create and maintain an extension)
My extension will allow the user to
• Zoom in to the page
• Speak a selected portion of text
• Restyle page contents for easier reading
Basically the extension is divided into these 3
parts

5. The interface is very simple
There is a button with the icon of a small
magnifying glass, on the Chrome tool bar
Once this button is clicked, a small pop-up
appears which allows the user to zoom in to the
text
Once the icon is clicked, the page contents
automatically restyle

6. In order to restyle the contents, I used a free
Java Script and CSS library called
ReadabilityRedux
Using this library, I inject the necessary CSS code
into the web page when the Magnifying Glass
button is pushed
Basically this function makes the font size
bigger, sets a large margin on the sides, and
applies an easy to read font type

7. The zoom function basically injects CSS code in
each page and sets the dimensions of the
contents
Inside the small extension pop-up, there are
PLUS and MINUS buttons for adjusting zoom
level
Alongside the small Magnifier Icon, there is an
even smaller zoom level indicator (generated
number with a colored background)
Settings are stored and loaded via cookies

8. Using the Google API for speaking text, and
Chrome’s TTS engine, I can “speak” a selected
portion of text
I’ve added an element to the context menu,
which appears when you right-click a selected
portion of text
After selecting, the text will be sent to Google
and an audio will be rendered
The text is filtered and a phrase of maximum 90
words is constructed

9. Many people ignore accessibility issues, which is
not a good thing, since this can result in many
lost users
A great idea would be to combine as many of
the existing solutions as possible
My ideas are not original, I’m not the first one
to think of an extension which can speak text,
but I am the first one to think of combining
these ideas into a single extension, which of
course, can be extended and improved
