This is great since CAPTCHA’s started popping up blind and visually impaired people have faced huge issues accessing anything online that needs a CAPTCHA. This has lead to people having to ask sighted people for help sometimes having to give out there log in details and other secure information.
Since they were initially launched there have been access improvements – many now have scrambled audio where numbers are spoken alongside what I can only describe as noise. Unfortunately this has not gone far enough the audio versions don’t work on mobile platforms and are often just as unintelligible as there written alternatives.
From the early days of the CAPTCHA there have been viable alternatives and quite frankly it’s about time code writers and designers start using them.
