Re: web-security technologies, CAPTCHA, v2

2 pionts

1. I am wondering if we should separate issues that people with less sever disabilities.For example the item "recognize functional elements, such as buttons, are clickable"
precludes any innovative solution being found. were as problems such as 
"read CAPTCHA text at all because of the intentional distortion of it"

is much easier to solve.




2. I would associate issues and cognitive function because people may have problems with one set of issues but not with another.
SO for example, people with impaired short term memory may have a good long term memory - hence providing a choice of "captur" type functions that depend on different cognitive skills seems towards a solution or more inclusive design. 

All the best

  Hi All,
  
 It would be good if you would please reply to this message with any suggestions for items, not included in the list below, of CAPTCHA-related difficulties.
 
 I have added two new items:
 ·      enter characters in the correct order; and
 ·      recognize characters if they do not form words, or are shown in different fonts/styles

  People with Cognitive Disabilities May Not Be Able to:
   read CAPTCHA text at all because of the intentional distortion of it
 comprehend text that can’t be enlarged without additional distortion
 recognize characters if they do not form words, or are shown in different fonts/styles
 have the advantage of comprehending the meaning of words or images
 understand text spoken in a computerized and distorted voice
 complete the multi-step procedure for submitting the CAPTCHA text
 complete a timed CAPTCHA due to slowness in completing all steps
 enter characters in the correct order
 understand the purpose of buttons such as reset, listen, and help
 recognize functional elements, such as buttons, are clickable
 focus due to irrelevant instructions such as “stop spam” and “read books”
 become accustomed to CAPTCHA because there are multiple versions of it
