Re: Comment about CAPTCHA article

Thank you for this comment, Kim.

I take your point that two is more than one, so we should adjust the
sentence you're pointing us to accordingly.

Are you aware of others besides reCAPTCHA that we might have also
missed?

Best,

Janina

And I would like to contest those descriptions because it was misleading to me, someone who had never worked in depth with CAPTCHAS before. The article makes it sound like onus falls on the site to make CAPTCHA's accessible to people whose native language isn't English because CAPTCHA's aren't multilingual. I have evidence that refutes that sentiment. It was these two sentences and this particular paragraph that drew my attention.

If you change your browser language, (which is also configured based on what language your computer is in) it will change the reCAPTCHA language. Therefore, the one of the primary CAPTCHA's that is described in the article is multilingual, however the site makes it seem as though there is only one true alternative (though I acknowledge that they stated that they were 'aware' of only one.) This bothered me because the article had been updated August 23, 2019. So it’s not as though it’s a dead piece of literature.

Clearly, this is not the case. Research has demonstrated how CAPTCHAs based on written English impose a significant barrier to many on the web; see Effects of Text Rotation, String Length, and Letter Format on Text-based CAPTCHA Robustness [captcha-robustness]. This problem is likely to increase when using Latin-script characters beyond the ASCII range, with accents and diacritics, or shapes not included in the set used for English. For example, speakers of Arabic or Thai may not have enough knowledge to identify a distorted version of such characters. Furthermore, users may not have the necessary keys available on their local keyboard. "

Especially the statement that "an assumption that all web users can understand and reproduce English predominates". This paragraph essentially mislead me to think that CAPTCHA's don't currently possess the ability to change languages and they pose a significant barrier for people whose language isn't English. And like the sentence above, I find that sentiment untrue based on brief testing on ReCAPTCHA that I've done.
