Apologies for cross posting. 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. Jeff will be speaking at the NADP Technology event on 17th September 2008 Feel free to pass this along to others who might be interested. Best wishes E.A. Mrs E.A.
