Mike,
 
  
 
I am reaching out to two of our nontechnical Blind users and get their opinions. I wanted to have the average blind person’s input. I should be hearing from them shortly and will keep you posted.

Subject: Vertical vs. horizontal scrolling on a mobile device
 
  
 
Hi All--
 
  
 
I've tried searching the lists, but haven't found anything addressing this question.
 
  
 
When is horizontal scrolling more accessible than vertical scrolling on amobile device? Always? Never? Sometimes?
 
  
 
For example, envision a vertically arrayed set of categories.  Touching each category heading causes an accordion to open, displaying a subset of items. 
 
  
 
Is it better to have the subset appear horizontally, requiring horizontal swiping or touching, or is it better to have the subset appear vertically, requiring vertical swiping?
 
  
 
I know that horizontal scrolling on a desktop is to be avoided, but horizontal scrolling seems to be, from a design standpoint, acceptable on a mobile device, to limit the length of page.
 
  
 
What if the number of subitems arrayed vertically is quite long; is it permissible to have scrolling within the array?
 
  
 
Any thoughts would be greatly appreciated!
 
  
 
Thanks,
 
  
 
Mike
