Hacker tools are needed for that kind of detection. If javascript can't do it a properly configured hacker tool can be used to detect that a screen reader is not being used in browsing. If a tool finds none of the directory paths that screen reader applications put on machines as well as screen reader executeables it's safe to say no screen reader was being used in the browsing. If javascript isn't allowed or capable of doing a directory search though, how is it websites detect flash isn't loaded though? -----Original Message----- From: programmingblind-bounce@xxxxxxxxxxxxx [mailto:programmingblind-bounce@xxxxxxxxxxxxx] On Behalf Of Homme, James Sent: Thursday, May 19, 2011 16:23 To: programmingblind@xxxxxxxxxxxxx Subject: Web Accessibility: Detecting Assistive Technology Hi, Is there a way through JavaScript or other means to detect that there may be a screen reader or other assistive technology browsing a page?
