I don't understand what difference it makes being in Klingon? usually Captchas are just jibberish anyway. Recognizing individual letters remains the challenge.
are you sure? I thought they were simply postulating that native speakers would more accurately 'capture' the characters of a word/phrase if they recognized it from their own language. If you know what a word is supposed to be, then it's easier to read messy writing. I realize I could find out by just reading the PDF paper, but I think it's worth answering here for the benefit of HN readers
Interesting. I just read the PDF to see - they were sending captchas where the goal was to translate a series of written numbers in the native language into roman numerals. So (une)-(deux)-(trois) --> 1 2 3 along with instructions for solving the captcha in the related language.
As best I can tell, the klingon used wasn't even in a latin font. So the correct answers were essentially translating arbitrary symbols into their associated numbers. Certainly throws off what I was assuming from the blog read.
They do note that the service, ImageToText, was the most expensive by far.
