I would like to say thanks to every body, who brought to my attention the issue of the Disability and Moodle. There are two types of the disabilities, which affect the Learners. The first one is the sight and the second is the hearing. In regards to the disability in the sight, I observed during my visit to our Central Public Library in BirminghamUK as follows: I saw a man used a public library's pc and he was a partial blind. When this person pressed the keyboards at the pc, this pc started to give a loud sound of the letter or the word, which he was typing it. I found this great invention so I asked Mr Francis Firth a librarian from University of Central England in Birmingham about the new technologies for helping the learners with sight disabilities. Mr Firth responded kindly to my question as follows:
The best-known (and industry standard) software for reading to VIP people is JAWS by Freedom Scientific but it is quite expensive. One of the better-known for those with dyslexia is TextHelp, which will help spell words. For word processing, etc, a well-known package is Dragon Dictate but another is called Naturally speaking. One of the best-Known screen enlargement packages, which also reads the screen out is called Supernova from Dolphin (this software has been used in our Central Public Library). For scanning text and converting it to a text file to be read out loud the industry standard is Kurzweil. I am very optimistic in the future that one or more of these software will be integrated into Moodle.
In regards to the help the learners with disabilities in their hearing. I would like to comment on this issue as follows:
I have some background on this matter because I worked on a project about voice recognition. Non technical speaking, all you have to do is to speak through small microphone connects into pc and then your words, which you have already spoken will appear as a text on the pc. These words can also be converted into a sign language. This project has great application and now is in very advancing stages.
Also there many research institutions are working to integrate the voice recognition software into Moodle. Finally I would agree that the scientific researchers are doing too little to help those learners with disabilities. However I am again optimistic in the future.
