Contrast can often be a problem
for people with Low Vision. Most designers
of operating systems recognize this fact and build in accommodations.
Windows has a series of “High
Contrast” themes to choose from, and also allows the user to assign colors,
sizes, and fonts to different elements of the GUI.
OS X has a feature where the user
can reverse the colors of the GUI. All
white elements become black; all black elements become white, etc. Apple has extended this reverse color accessibility
feature to iOS on the iPhone and iPad.
The problem with this approach to
accessibility, which I utilize all the time in Word or Excel, is how it then
impacts the user experience on the internet.
When the system colors are set to be reversed, they apply that theme to
the internet without discretion.
Photographs and Video suffer the same reversal of colors as text, when
in most cases, an ease of reading text is all the Low Vision user is seeking.
A tool I’ve found useful in keeping
the graphic part of my internet experience clean while still being able to
easily read text in reversed black background with white letters is the Firefox
plugin Blank Your Monitor + Easy Reading
Once installed, you just right click on an article and then click “Easy
Read” at the bottom of the dialogue box.
A new tab opens up with a black background and all the text from the
page in white.
Fairly easy to read, except for
one annoying thing. Literally, ALL the
text on the page is rendered out, including the headers, logins, the follow us
on…, captions under pictures, footers, etc.
It can be kind of like those puzzles where you try to find the words
vertically, horizontally, and diagonally from a full page of letters (OK, so maybe I’m exaggerating a little).
The current version 1.9 of Blank
Your Monitor + Easy Reading was released in October of 2013. What I’d like to see in a version 2.0 release
is some combination of the reader feature in Safari that does just render out
the body text and the reversing of colors that is the main accessibility
feature of the current app. But for now,
Blank Your Monitor + Easy Reading is a nice little add on to consider if you’re
like me and have trouble reading web
pages.
