The In-accessibility of CAPTCHA

Don't you just hate CAPTCHA... "Completely Automated Public Turing test to tell Computers and Humans Apart"? The user experience of using CAPTCHA is terrible, and always a pain. I often get them wrong, and they slow down the browsing experience.

They are also in-accessible.

Recently, I have seen an increase in audio CAPTCHA which is a positive step (at least accessibility is being considered), but an alternative would be better. ..

Here is a detailed spec writing by W3c discussing the possible alternatives to CAPTCHA:

In addition, here is an article from WebAIM discussing the alternatives to 'spam free accessible forms':

These articles certainly leave food for thought.

In a future post, I will discuss SAPTCHA (Semi Automatic Public Turing Test to Tell Computers and Humans Apart) which is a proposed solution to the accessibility problems of CAPTCHA.

Let me know if you have any thoughts / comments regarding SAPTCHA, CAPTCHA and it's various alternatives.
