However, if the audio captcha systems have not been broken then they can continue being used as they are today. <br /><br />In other words, there would be two separate and unrelated ways to prove you are human, one an audio prompt asking you to type letters and the other a better visual prompt, in this case, asking you which way is up. <br /><br />I really should research the solving of audio captcha but my central point is that these two modes can be completely distinct, they don't have to be alternate representations of the same prompt.Chris Mountfordhttp://www.blogger.com/profile/03560327085364406517noreply@blogger.comtag:blogger.com,1999:blog-2759480248865232582.post-51605137069293402552009-04-23T21:16:00.000+10:002009-04-23T21:16:00.000+10:00Interesting post, Chris, as much for the broad topic of captcha as this particular development. <br /><br />But with regard to the up-captcha, how do you see audio working for people with vision impairment? With a letter string, the audio reads out the letters, both triggered by code. <br /><br />What would the audio for up-captcha say, and how would that be tied to the visual representation?ronsmanhttp://ronsman.myvidoop.com/noreply@blogger.com
