Hello All,
I am making some efforts, in association with others, to set up a bootable USB stick with Knoppix for the Adrienne audio desktop for a blind user. Since they are a diabetic, and have regular finger pricking for a blood sample for the sugar levels, setting up a braille output device is not an option.
I am cooperating with another person by email (and snail mail, to the
US) in this endeavour. I would appreciate comments about which browsers are better with various audio environments, and to remember that the established system will require to be run solely by the audio, including confirming all typed keys for input. In this regard, it may even need to report the actual keys typed when providing the password. Yes, that is quite insecure, but will be necessary for the targeted user to be able to log in.

From a hardware point of view a small box with a 3,5 mm stereo male ended fly lead to the speaker output on the PC with a toggle switch selecting between two 3.5 mm female sockets. Plug the PC speakers in to one socket and a set of headphones in to the other.
This gives the user quick selection between speakers or headphones for privacy when entering personal or sensitive information. Of course if this is for a laptop or portable OS on other PC's this wont be a suitable method but for a home PC it works. I don't know if you can buy these of the shelf but 15 minutes with a soldering iron and about $10 in parts is all that is needed.. -- Mark "Pockets" Clohesy Mob Phone: (+61) 406 417 877 Email: hiddensoul@twistedsouls.com G-Talk: mark.clohesy@gmail.com GNU/Linux..Linux Counter #457297 - "I would love to change the world, but they won't give me the source code" "Linux is user friendly...its just selective about who its friends are"
