Re: Are All Capital Letters accessible?

Then, there is this spanner in the works

Letter case and text legibility in normal and low vision
Volume 47, Issue 19

It is thought by cognitive scientists and typographers alike, that
lower-case text is more legible than upper-case. Yet lower-case letters
are, on average, smaller in height and width than upper-case characters,
which suggests an upper-case advantage. Using a single unaltered font and
all upper-, all lower-, and mixed-case text, we assessed size thresholds
for words and random strings, and reading speeds for text with normal and
visually impaired participants. Lower-case thresholds were roughly 0.1 log
unit higher than upper. Reading speeds were higher for upper- than for
mixed-case text at sizes twice acuity size; at larger sizes, the upper-case
advantage disappeared. Results suggest that upper-case is more legible than
the other case styles, especially for visually-impaired readers, because
smaller letter sizes can be used than with the other case styles, with no
diminution of legibility.
