Dear List,

Dolphin has an EPUB reader (Easy Reader) that enables a realistic framework
for understanding the impact of the WCAG 2.1. For EPUB docs that provide
reflow, you can enlarge to 600% with reflow. Note: if you want to see the
font-size you will get with with the Reflow Criterion just set your
resolution to 1280 width and pick a height that fits your screen. Then 400%
will give you the WCAG 2.1 effect from the Reflow Criterion.

The app gives you letter and line spacing, but no word or paragraph
spacing. You have good control of margins.

Beyond WCAG the app has a the ability to choose from 16M colors. For text
and background. The app also gives you a choice of font family. You can
choose the books font, or one of six other fonts, 3 serif , 3 sans serif.

Finally, the app has a read-aloud that will track your place as you read.
You are given two color choices: one for sentence highlight, one for word
highlight. If you set them to different colors you have sentence and word
tracking as you read. If you set them to the same color you just have
sentence tracking. If you set sentence tracking to the background color you
only have word tracking. If you set background, sentence and word
highlights all to the same color you have no tracking.

This is not a plug for Easy Reader it is just an observation of a place
where you can see the things the LVTF placed in our requirements and most
of what was implemented in WCAG 2.1.

If you download your free trial you can use the Gutenberg Project for text.
EPUB is a download option. If you have low vision, just go to Bookshare
they have a better selection of books. The app lets you choose from several
public libraries.

For those of you with low vision who spend your time fighting horizontal
scrolling, this will give you a good idea of what it is like to read print
that is big enough with reflow.

Best, Wayne
