Avoid Use of ALL CAPS
 
Avoid ALL CAPS sentences. ALL CAPS can be difficult to read and can be read incorrectly by screen reader.
 
An ALL CAPS word creates a parallel edge at the top and bottom, giving the word a low shape contrast. Text in Non Caps shows multiple adjacent edges at the top and bottom, give the word a higher shape contrast.
 
Example of Word Shape Contrast 
 
Word Shape Contrast
 
The more non-parallel edges your text has, the higher the shape contrast. High shape contrast makes words easier for users and easier for screen reader to recognize the word. 
 
Screen Readers also have difficulty translating/reading text in ALL CAPS. The following example is what a screen reader sees and translate an ALL CAPS sentence. The result is no longer readable or understandable.
 
Example
 
Text on Screen              THIS SENTENCE IS IN ALL CAPS
 
Screen Reader                T. H. I. S. S. E. N. T. E. N. C. E. I. S. I. N. A. L. L. C. A. P. S.
