It was a few months ago that I read about the inauguration of the first internet cafe for the blind in Islamabad. I had wanted to write about it earlier but somehow skipped my mind, until the recent discussion on Islamabad allowed me to jog my memory a bit. I do want to share the news, even if a bit belatedly, because it is so uplifting and empowering.

According to a report in The Daily Times, the country’s first-ever Internet café for the visually impaired was inaugurated with the help of generous funding from the World Bank and the Pakistan Foundation Fighting Blindness (PFFB).

It appears that the software technology that enables such a user experience for the blind was introduced to Pakistan by an ATP regular, Aqil Sajjad. The software used by the internet cafe is called JAWS, and was first introduced by Aqil to Pakistan in 1999. Aqil has since then moved to the US for graduate studies in Physics, but the software is now more widely available to the blind in Pakistan, and making a dramatic difference in their lives.



These software packages are quite expensive but are really remarkable in what they are able to achieve. With their assistance, blind are able to operate the computers without any sighted assistance. It requires no special hardware and can be installed on a standard Windows machine, essentially making Windows accessible to a blind person by providing speech output as a substitute for the information displayed on the monitor for sighted people.

It is awe-inspiring how a software solution has made it possible for the digital world to finally become accessible to the blind. For once, there is a chance that the technological gap between the blind and the sighted may close. I am told that it is not just the simple use of computers that has now become possible with these softwares, but with a few accessory technologies, many other important intellectual tasks have also become much easier for the blind.

For example, the blind were previously dependent on sighted people for access to reading material. However, thanks to the internet and the availability of such software, that is no longer the case. Now one can even find entire coursework from some of the major universities (such as MIT) online, including class lecture notes, homework assignments and examinations.

In addition to this, by using a simple scanner and OCR software, they can now even read books on their own. Scanning books does take a bit of extra time, and the recognition is not 100% perfect (there are some errors), but having this option for reading a book without any sighted assistance is nothing short of a blessing. It might be worthy to mention here the project launched by Google to place a significant number of library books online.

While JAWS and Windows Eyes are good for general use, such as operating Windows, word processing, e-mail, internet surfing, instant messaging etc, doing Math (and in Aqil’s case, also Physics) with them is tricky. For that purpose, special software is now available and carries high recommendations from users.

One such software for Mathematics use is called WinTriangle. According to a Harvard paper from a set of conference proceedings on this topic, a new conversion tool, LaTeX2Tri, makes LaTeX files of physics and mathematics accessible to blind or visually impaired users of WinTriangle. Through a variety of pathways, common file types, such as TeX, Word, and PDF, may be converted to Triangle, the working language of many blind or visually impaired students and researchers. Textbooks, arXiv preprints, class notes, and problem sets are now readily accessible to WinTriangle users, completing the loop of mathematical communication between the blind and sighted communities.

I am inspired, not just by the progress that technology has made to make resources available to more people than before, but also by the committment and personal motivation showed by the blind people in Pakistan. They managed to reach out and find a solution for their needs and are now making it more widely available. However, a majority of our country does not speak, read or write in English, and I am still unaware of such software being available in Urdu. Unless it already exists out there, this presents a great opportunity for Pakistani software industry to contribute to the society.

For those interested, JAWS is published by Freedom Scientific and is available online for download. The price of Jaws is about $1,095 for the professional version and $895 for the standard version. Unregistered versions require a reboot of the computer every 40 minutes. However, a demo version of the program is available free of cost. A similar program called Windows Eyes can be downloaded here. The Mathematics software WItriangle is available here.

    I ma with a Master’s degree in Mathematics (from the University of Peshawar, Pakistan) and with low vision (visual acuity less than 3/60); I am working as Lecturer in Mathematics at Government Degree College, Oghi, District Mansehra, NWFP, Pakistan.
    I am interested in the Math software for the blind, WinTriangle: Who has it been developed by? Where can I get it and how? The website of the company behind the development of this software will certainly be of use.
    Last, but not least, I would be glad to offer my services for the advancement of the blind and visually impaired in the areas of Mathematics and Computer Science.

    I first posted this under another topic but thought it probably belongs more here.

    One issue of course is that Jaws and windows eyes are not perfect. Sighted people often design webpages and software that is not necessarily fully accessible through a screen reader.

    Fortunately, a lot of good work has been done in the area of webpage accessibility. The “web standards project” is working for some standards for making web technologies accessible for all:
    http://www.webstandards.org

    the following on-line tool allows you to enter the URL and get a report on its accessibility:

    Their home page also has some accessibility guidelines for webpage developers:

    This is a good step certainly. Technology can hep us cross these hurdlesand allow people to reach their full potential.

    Can somebody tell me (and the public at large ) the name of a single Pakistani Inventor of any machine ? I asked this question to many but none could answer, not even the Kasauti-fame guy or even the editors of leading newspapers here in Pakistan !

    Naveed: Thanks for this useful information. I will try to find people in Lahore that you mention. Maybe they have non-technical bottlenecks that some of us can help solve, such as finding some funding sources.

    Just got this brief from a friend. I read Dr. Salma Maqbool’s bio and was very impressed with her work for the blind. May her soul rest in peace:

    (Dr. Salma Maqbool) was the chairperson of Pakistan Foundation Fighting Blindness at the time of the inauguration of this internet café. She passed away just last month – you can read more about it (if you are interested) at:

    Aqil,

    I did a little background research and here is what I came up with.

    A Text-to-Speech Synthesizer can be broken down into two broad categories i.e. Natural Language Processing (NLP) and Speech Synthesis (SS). NLP deals with parsing the text and building up a ‘language’ database. The models used here are the same ones used in an OCR and grammar correction software i.e. hidden markov models. The ‘phonetic’ layer of the language is then overlayed onto this ‘language’ representation. This part faces the problem that you mentioned regarding urdu not having any vowels.

    The search also revealed the research group making headway in this area. Its called the Center for Research in Urdu Language Processing (CRULP) and is at the National University of Computer and Emerging Sciences (NUCES) in Lahore.

    It looks like they had made some real progress in the area. I’m pasting the links below. These guys definitely deserve recognition.
