Google
has launched its laboratories in a version of its search engine
"accessible", that is to say simply understood by blind and visually
impaired users. It focuses in particular the results pages that are easily understood by users with disabilities.
Much of the Internet has nothing to do with accessibility, but the
developers of web sites must bear in mind that some of their potential
visitors may have a disability that makes browsing the web difficult.
At the forefront of these physical disabilities, there are vision
problems that require some people to navigate with a tablet Braille,
special browsers or devices responsible for content written transcribe
oral Web.
To make it easier for visually impaired people, Google has launched a
test version of its search engine focused on accessibility.
It includes the accessibility of Web pages to the criteria used to rank
the results returned in a query and favors sites that can be viewed
using special devices for the visually impaired.
To do this, the engine analyzes the composition of pages, content
prioritization, the presence of alternative tag and complexity of the
layout to determine the level of accessibility. Recognized
as the pages are really accessible then valued in the result pages, to
the detriment of those who do not follow some basic rules or have
contained too rich to be operated by a visually impaired person.
