Hi,
I just connected to your website and the first "bafflebot" submit to me is "what is this character's name" (a yellow bird) I'm from France, I dont know all the US kid cartoons so I cant answer to that captcha.. Whereas 1+2 or "enter the word" is pretty universal.
Second try, I have in front of me a red apple with legs and arms and the question is "what is it?"
The question is wayyyyy to broad, what should I answer? is it another cartoon that I'm not aware of? is it an apple? a red apple?...
A captcha must be VERY simple and universal.
I read a few months ago a good captcha idea, a picture of a human and the challenge is to say if it's a man or a female. A bot cant read the picture well enough, but the human eye/brain is trained to identify a man or a female in less than a second!
My 2cents, good luck with your project. I agree captcha generally sucks
Another idea along these lines would be to present a scene and ask the user how many objects are in the scene. It's a very difficult problem for computers to descern individual objects in a scene, especially if they overlap.
It's also not so good for the visually impaired because you can't really provide an audio version of the challenge, whereas identifying the letters in a random string is easier to present as audio.
That's true. Maybe you could do something with profiles from FB. Show a small collections of faces one of which is your friend on FB. Then you have to select your friend. For the visually impaired you could read peoples' names.
A real person would instantly recognize one of their friends and even the guy getting paid to solve captchas would have a hard time.
Of course, you then have the problem of getting someone to connect FB to the CAPTCHA service for the first time instead of abandoning the form.
