Jennison Asuncion reports that a study of audio CAPTCHA technology is being conducted at the University of Washington:
A friend of mine, Jeff Bigham, a Graduate student at the University of Washington in the Department of Computer Science and Engineering is conducting research into audio captchas, the goal being to use the results to inform future development. Whether you are sighted or have a visual impairment, if you are interested in taking part in the research, go to http://webinsight.cs.washington.edu/webeval/captchas/ – the study should take no more than 15 minutes, and you will need to install the latest Flash player, if you don’t have it on your system. Feel free to pass this along to others who might be interested.
We urge everyone to participate in this potentially important study which may serve to impact future development of audio CAPTCHA as well as the overall accessibility of human verification and visual authentication technology.
