[blindkid] screen reading software

[Rosina Solano]

I am trying to find out if anyone out there knows anything about the free screen reading software for vision impared that is portable and just plugs into the usb port on any computer.  I heard about it several years ago, but am only just now thinking it would apply for us.  I guess it is self contained so that kids can take it everywhere so that all computers would be accessible.  If anyone knows about this software, please let me know.
