Detecting Screen Readers

myca Community Member Posts: 3

I attended the 2010 Lectora Conference and there was a presentation on how to be 508 compliant. Inside the course presented, the developer had an action/javascript that automatically detected if there was a screen reader. Can anyone tell me how to do this?

I am creating an audio intensive course, and am directing people down one of two paths based upon whether or not they have a screen reader. If I can have it automatically detecte the screen reader it would make the course much smoother.

Thanks for the help!
