When you say "they don;t work at all", do you mean in terms or reducing spam
or in terms of accessibility?
The questions can be randomised and made more complex for a computer to
answer. If for instance instead of having the question as '3 + 5' you had
the numbers written in plain english, ie T H R E E etc. It would work for
Jaws. From what I have seen of some of the bots, they are not that
intelligent. I am not saying they may not become more intelligent, but if we
can reduce form spam from say 100% to 10%, and be accessible without complex
processes, that would be a good achievement.
It would be very easy to randomise the questions so the computer would not
know which it is getting.

I recently read an artical saying that visual capshas are easy to get
around. They don't work at all. The problem with questions like that is
that computers can be used to get around them. How would you get around
this. I thaught of mis spelling something so it would sound the same with a
screen reader, but wouldn't look the same for bots.

Hi
On the Captcha matter, we are doing some research ourselves.
In order to avoid captcha and the audio, and the complexity and so on, we
were thinking of using a question such as what is 2 + 3 and you then need to
enter the result to validate the form. I have seen it used and I like the
simplicity of it.
Have you seen this type of stuff and if so, what is your opinion?
