Computing for Near-Blind Children?
mjpaci asks: "One of my co-workers has a son, age 12, who is visually impaired among other problems. He is smart, charismatic, and funny--an all around good kid. Due to complications during his mother's pregnancy, he is near-blind. His father is a saint and spends many hours each night helping his child with homework. The problem is that the child is now taking Social Studies in junior high and has great trouble with geography as he cannot read the maps in the book even with his 'overhead visualizer.' Can Slashdot help me help this child?"
"One of my clients has donated 21" monitors to him in the past and they have helped. The real rub is, even with the large monitors, the child cannot read maps when zoomed-in on. The father has looked to the end of the earth for good, hi-res maps that can be magnified without great pixelization. Are there any good sources out there for hi-res maps for educational purposes or a software package that could help? Questions like: Find the largest city on the Mississippi River and what is the Capitol of the South American country to the west of Surinam are hard for the child as his view of the map is very constrained."
This is part of what truly makes the Slashdot community great, and why I am proud to be a part of it. Geeks helping out others by poling a resource that has a truly flabbergasting diversity of combined knowledge. This question hits a bit close to home as my research is centered around vision and vision rescue strategies, but this is a more immediate need that I truly hope somebody here can help with.
Just to clarify: I am not sure if you are asking for screen reader software or not as part of the solution? If so, there are a number of alternatives for Windows (fairly pricey), but the next version of OS X will have a built in screen reader solution! combined with other visual aids that will help the blind and near blind use their computer systems without having to invest in another solution.
For the maps, there are a number of high resolution maps available from the USGS which can be obtained in digital form here and in atlas form here. In addition the CIA world factbook is a nice resource for kids with text and maps that can be remapped with higher resolution.
Finally, a last resort would be Adobe Photoshop. You can take any map or image and simply resize the image with a much higher resolution (say take a map from 72dpi to 600 or 1200 dpi). If there is enough information in the original image to interpret, this might be a good solution to allowing one to zoom in images and maps for ease of interpretation.

I use Garmin's Mapsource quite a bit which, whilst not being the prettiest, turns detail off as you zoom out and adds it as you zoom in, which sounds like it could be helpful.
It isn't cheap, but, I am sure if you contacted their PR department and explained what you wanted to do with it, they would have a hard time coming off as anything other than heartless and moneygrabbing should you they refuse to give you a gratis/cheap copy.
The North American web demo of their maps (link near the top right) does similar and may even do the trick, and, is free to use.
As for large screen helping, a cheap projector and a dark room would be a better logical alternative than a big screen it would seem to me, but then again, I hardly know whereof I speak.
I feel for your coworker's predicament. My mother and brother have had a total of about fifteen surgeries between them to correct vision problems mostly stemming from retinas that have a tendency to detach, and complicatons thereof. The condition has many of the symptoms of a connective tissue disorder called Stichler-Sachs, but not all. In many cases, it boils down to a combination of the aforementioned, and a nearsightedness that puts a strain on the eye from its length. I got away with one surgery twenty years ago, while my mom and brother have basic vision of shapes and/or colors (with no semblance of stability in sight).
Regardless, I've been through much of this before. First off, make sure his school is accomodating with a IEP (individualized education program)/504 setup. There are many things you can do, but without help from the school, it's won't help. Many accomodations can be made "behind the scenes" and without making the child self-conscious. There are some things that the child can't totally hide, and in this case a sense of humor is particularly helpful.
Many times, the school can obtain (at the school's expense) extra-large versions of books, graphics, diagrams and the like. I know when I was a kid, we had a few raised (molded) topographical maps (? somebody help me out, I can't think of what the right description is) sitting around. I know they also have globes, but they may not be as "high-resolution" if he's studying, say, state geography. They're also not that difficult to make, which can be a family project. The point is to cover all the bases by connecting knowledge with touch and what little sight he may have: think teaching art via texture and collage and sculpture as opposed to traditional "visibles".
In this case, geography may require a rewritten or oral test for the child. Since he had to learn it differently, it may have to be tested differently. YMMV based on what the parents and educator think is best.
Many different ideas can fun or degrading, depending on how severe the disability is; that's true of many accomodations, so it's important to be sensitive to the child's attitude, especially at this age, and moreso in a few years.
Whatever your suggestion and the parents' decision, it won't be a quick fix; this is a long road. I know from experience, however, that with a lot of support, it's definitely doable. I wish you the best of luck. (I will gladly answer questions if you e-mail or reply to this post.)
Seems to me that would be the ultimate solution. If you're not familiar with the device, a braile monitor uses steel pins at different heights on a flat, horizontal field to represent colors in a computer graphic. It seems to me that would be the solution required here- but I'm not sure where to get one (as I'm not blind myself) nor have I seen one in several years. You might check out a few schools for the blind and see if this technology is still available.
SJW: a person who perceives an injustice, and while correcting it, commits a greater injustice.
I got Microsoft streets and trips for use with my GPS device. The nice thing about these maps is that they are meant to be used down to the street level and even let you select every available address in America.
Within the US, you can view the entire nation and zoom in as much as you need. Imagine how PDF files work - the information is stored in database and is not pixelated by maginifcation. This would help for any US maps.
For international, the same suite (Streets and trips 2004) works on the city level, but only has major streets. You would have to find the speicific maps you are looking for.
Perhaps you could contact that guy from MIT who has all of the implants and stuff. The "bionic man". I'm not trying to be silly here, but it may be possible that he or someone he could put you in touch with would be able to help the child (or even associate with him on the basis of a project) with some sort of augmentation.
I don't necessarily mean some sort of physical augmentation - but some sort of technical assistance that would help paint images onto his retina in a way that he could see the material on a computer, through an adapter, in the same way that some of the new "head monitors" do.
It's a long shot, granted - but it might be worth a shot? If there isn't a solution out there now, get the kid and father in touch with people on the foreront of technology and science and they could possibly actively pursue a solution with interested professionals.
It'll take down another avenue for learning.
How about a relief map of the world that is also a puzzle. Ocean names are in raised text, and the continents are inset into the board. Each piece of the puzzle is a country in the continent.
By feeling your way around the oceans, you can feel the 'holes' where the continents go. Then you fit the pieces into the holes, learning which countries go with which continents as well as geographical features.
Maybe breaking it up into smaller pieces will make building a larger picture in the mind easier.
That's ok, Jesus likes me anyway.
a company called GH, LLC. The specialize in converting educational materials from traditional sources into raised print -- braille text and raised lines for diagrams. This is for totally blind individuals (obviously) but should serve your child as they would be able to feel raised maps. Note that I am not affiliated with them - just knew some people who worked there.
Another great resource is the Alliance for Technology Access. They have directories of companies that create technologies for handicapped individuals.
Good luck.

the RNS marine mapping system includes a vector based mapping system that zooms to any level, can be blown up, ect. www.raytech.com I use this on my boat :).
This might be of interest to you. Not sure how visually impaired the kid is, but this is for those with no sight at all. BATS
About the only thing I can think of is to make a "3D" map. I don't mean a relief map. Take an existing map, and put it on carboard or something. Put something along the borders that raises it up. Tulip Paint (a really thick paint applied like Icing), Silicon Glue or wire should work for this. Essentially, think along the lines of helping out someone who is completely blind.
Also, it might be possible to take a couple of those monitor, run them through a splitter and have each one displaying 1/4 of the picture.
Fly me to the moon Let me sing among those stars Let me see what spring is like On jupiter and mars
Put those questions into google, and you can pretty quickly find an answer using only text. Using google to answer questions about maps is probably not the skill they were trying to teach, but on the other hand, it is a skill of some kind.
The Speakup Project produces a screen reader that is used in the above distro.
There is also a Knoppix based distro called Oralux, that will also support braille terminals (these are usually one line at a time vt100 emulators) connected to a serial port.
I know this does not solve the map problem, but this, along with Links, for example, will give any vision impaired person far more tools that are available in Windows, for instance.
And that is what gives those people a chance to score in the world, they can exploit things others tend to ignore. And if the kid is willing to learn, then we should provide him with the resources he needs.
You could try a Virtual Retinal Display. They've shown promise for people with macular degeneration and retinal pigmentosa. I think Microvision is the only company selling them though.

Slashdot did an article on them a while back.
http://slashdot.org/articles/99/04/15/2058223_F.s
The first thing I thought of when reading your question was "tactile graphics". In my experience, it's the best way to convey spatial distances when one can't see the distances. A tactile graphic is, for example, a map with details raised, effectively making it so that the individual can "feel" the distance and relation of different features. The drawback is that these graphics are expensive *and* tend to be very large (it's difficult to feel the separation of two tiny lines when they're close together). A quick google will find you plenty of information on companies that make these products. (I happen to work for a company that makes tactile gfx, in addition to other low vision/blind products, but no plug for them today)
I read this fascinating article some time ago. With the way the way things are headed the kid might have 20-20 vision soon ;-) I'm sure there are all sorts of neural type implant projects for vision impaired people, so the future looks bright.
Why would you think this would cheapen the kid's plight? Telling him he can't do something with kids his age because of a disability and that he should put his life on hold until something with a time-to-market of 20 years shows up?
Yes, sarcasm. With all due respect, I understand your position, but it's a cop-out answer.
There are certain things kids with disabilities can't do, obviously. A kid with paralysis of the lower body can't run track. But the point is to show these kids what they can do, not what they can't. He may not be able to run track, but if he wants to be near the sport, there are plenty of wheelchair track clubs he can participate in. Instead of telling the kid, "wait until we develop artificial legs", let's tell him we have the best people in the room, and until then there are plenty of other opportunities and ways he can participate in life just like non-handicapped people.
A kid with vision disability can participate with his classmates in geography, but he might need some help. Help which, I should note, is required by law and for good reason. People with disabilities aren't invalids, but may require accomodation.
It's worth noting that social studies probably isn't an 'elective' for him in junior high.
Windows XP has an Accessibility menu with Magnifier and Narrator. Most map software use vector graphics, so zooming in doesn't degrade the image. Speech to text software could be nice if the keyboard is too cumbersome to use.
I would recommend installing two or more monitors which can be configured (since Win98) as one big desktop. Or maybe plugging the PC to a large TV with svideo or better. Most video cards also have custom brightness/contrast settings. XP's "built-in" ultra-plain generic drivers doesn't allow that, be sure to download new drivers.
Also, it's important to know about government and private institutions benefits for handicapped persons - especially for education and training.
All the suggestions are decent ideas, but I wonder if the solution might be to change the problem.
If a person has such problems reading maps, that simple image enlargement techniques don't help then why try teaching geography visually? It is unlikely that that skill (Being able to find the Mississippi on a map) whill ever be a useful one to a person who is severly visually impaired. You can visually describe geography to someone and achieve the same end.
Tell the teacher to stop wasting time teaching skills that aren't ever going to be of use. Just because a standardized skill test has a question like that doesn't mean that it will be applicable to every child that takes the test...
HA! I just wasted some of your bandwidth with a frivolous sig!
Macs have always had good support for users with visual and physical disabilities. In OS X, go to System Preferences - Universal Access. The visual enhancements availabe there can switch the display to black-and-white, greyscale, enhance contrast, and can magnify the display greatly for people with low vision. Zoom can be set from 2x to 20x. On my powerbook, 20x zoom makes the mouse pointer almost 3" long, which should be plenty enough for anyone that's not completely blind.
These enhancements are part of the base OS, there is no additional software to buy.

Create suitable images according to the need of the moment using the GMT software and project them onto a horizontal board. Us the projected image as a guide to making plaster reliefs. Great educational fun for folks of all ages who want to learn that there is a real World out there which is more than just target co-ordinates.
I worked at the CNIB (Canadian National Institute for the Blind) for some time...
A very valuable tool for youth (typically provided by the educational institution) is to create tactile maps, in which thin strips of foam are used to represent maps which can produce:
- Directions in a Neighbourhood
- Basic City Plans
- Geographical Maps
Basically, you take a piece of hard construction paper, and glue strips and curves of thin foam to it, and name each section with braille.
For further information, reply and I am willing to assist.
Emacspeak is a speech interface that allows blind and visually impaired users to interact independently and efficiently with the computer. Available free of cost on the Internet, Emacspeak has dramatically changed how the author and hundreds of blind and visually impaired users around the world interact with the personal computer and the Internet.
In my humble opinion Emacspeak is the most advanced voice enabled user interface currently available. If I wouldn't have seen a trained Emacspeak user reading his email faster that I ever could I never would have believed it. Did you ever see a person which is blind playing Tetris amazingly fast? It sounds incredible. Emacspeak makes it possible.
I won't tell you that you don't need some training until you are at home with Emacspeak. But if you are willing to invest some efforst, chances are good that you will be able to handle your computer faster than many sighted users.
When reading, writing, designing, or programming, the totally blind individual is inevitably restricted to a one dimensional world, be it speech or braille. This linear stream may take the form of a single-line display on a braille output device, or the words spoken by a speech synthesizer. There are brief moments when the blind user can enjoy the benefits of a 2-dimensional presentation. If he has a braille printer he might print out a chart or spread sheet and explore it with both hands. Indeed, when I studied mathematics at U.C. Berkeley I often had to write the equation, or set of related equations down in braille, and review it as a whole, before I understood it. However, one rarely has the time to construct such a two-dimensional tactile representation, similar to the screen or the printed page. As a general rule we must admit that the blind user is stuck in one dimension.
Unfortunately, almost all modern applications present information in a two-dimensional format, and most employ graphical icons that have no meaning for the blind. Since it is impractical to rewrite all these applications, the blind community has been forced to perform a rather awkward retrofit, using various adapters. We should recognize that this is not the ideal solution. Pasting a screen reader on top of Netscape makes it accessible, but the result is hardly efficient.
Over the past decade a small minority of blind users have discovered Linux, a free, text-based operating system for the home computer. Linux applications rarely employ graphics, and most of them are already linear, just like the mode (speech or braille) that is our Karma. All other things being equal, Linux is the best operating system for a blind user.
Of course things aren't always equal. If your job requires the use of a proprietary order entry system that only runs on Windows, then you'll be using Windows, with an adapter that tries to make the application somewhat accessible. But this scenario is actually quite rare. An employer may insist on a Microsoft Word document, but that doesn't force you to use Windows. You can write html code on Linux and mail it to your boss, who can then import it into Word. Conversely, your co-workers can easily export their Word documents into html for your benefit. There are very few reasons why you must use Windows. Let's assume you are considering Linux, where the applications are less graphical. That's a fair assumption, since you're already visiting this web site.
If you watch a sighted Linux user for an hour, you will notice that he spends most of his time in screen applications. He doesn't need the labyrinth of "helpful" menus and drop down boxes that Windows is famous for, and he has no patience for the "are you sure you want to do that" and "click ok if you really want to quit" dialog boxes, and he
Technology is great stuff, and all, but...
My stepdaughter is in a similar predicament as the poster. Her vision isn't as bad as "near-blind", but one eye is near-blind and the other is severely nearsighted.
My wife has always been her primary advocate in school, but we've done much of what the parent poster has done: get an IEP (even though she's at a private school which isn't required to follow an IEP, they do so), and use it to get enlarged books (they're free) and worksheets, and special consideration for homework (she's only required to do half as many math problems, for instance) and tests (her time limits are always extended).
She's tried electronic devices to enlarge her books and papers, but since she had to wheel it from classroom to classroom it was both unwieldy and very obvious -- not a good thing for a peer-conscious preteen. So yes, they have those devices and they work, but they're not as good as simply enlarging the books and papers. (I look forward to the day when all the textbooks come on an electronic tablet which can simply enlarge the font and/or invert the black and white as needed.)
Telling your child to have a sense of humor about such a situation is easier said than done; I'm sure we all remember how cruel kids of any age can be. The better thing to do is, as a parent, be understanding, comfortable, and above all be a strong advocate for his/her needs. Don't expect your child to speak up when he/she needs special assistance, because that may not be in his/her nature. But do ask him/her about any problems in the classroom and go to the teachers, or principal if necessary, yourself to correct it.
I don't know where you are located in the country (or the world), but many states have agencies designed to help solve these problems. I am visually impaired and I had a case worker from Connecticut Board of Education Services for the Blind throughout school who helped me with these issues. They have assistive technology consultants as well as people who can deal with the often public school administrators. Other states have similar agencies as well. Middle school can be absolutely hellish so it can be very helpful to have someone on your side. Even if this isn't an option make sure he has an IEP (or equivalent) so that the school has written records of his disability and a formal plan for dealing with it. If you've got all of this on file than its much easier to get individual teachers or administrators to help out, and even possibly pay for a special equipment and large print books. I actually was really good at geography as a kid, (national geography bee state finalist way back when) but I suspect that was because I really liked puzzling over maps and trying to figure them out. However, I know that geography bee national finalists have been completely blind in the past. To be honest if the tests he has to take are entirely the questions that you listed than they need to be modified, but geography is more than capitals and directions. A good question might be something like "What do Mindenao, Correigidor, and Luzon have in common" you don't need to know anything about the shape of the Philippines to answer that one, all you need to have done is maybe read a little about WWII or current events etc. I doubt that I could draw a map of the world better than a 5 year old but I can assure you I know much more geography than the average american. The truth of the matter is that this kid might not be able to give you directions from a little roadmap on the highway without a lot of help, but that doesn't mean he isn't capable of understanding the nature of the world around him. I suspect that the best thing for him to do is to read as much as possible and to try to absorb information and visualize it. That worked for me anyway.
Helping people is, I think, one of the best uses of the slashdot community. That being said...
Here are some (hopefully) helpful resources:
American Printing House for the Blind:
They're a great resource of learning materials for the blind. (You should try and see if the school can (or maybe should) pay for these materials)
APH geography learning materials
Royal National Institute for the Blind (UK)
The RNIB looks like a good resource and charity in the UK for the blind as well.
This article in the 4th issue of their Curriculum Close-Up magazine dealing with learning geography for the blind might help as well.

I hope this helps and I wish you and them the best of luck!
The CIA World Factbook has some EXCELLENT reference maps, available in 100% vector PDF (meaning they can be infinitely scaled without any pixellation).
I can't help with your specific question. However, there was a REALLY good cover story a few weeks ago in the New York Times Magazine on a child with cerebral palsy being integrated in the classroom. It describes an effort to truly integrate children with disabilities as though they were any other student. It may very well provide some answers or ideas that your friend might have, outside of your specific request. As it happens, just today I scanned this article in (6 MB), (I have two nephews with cerebral palsy) and would be happy to email it on to you or your friend. Email me at AT yahoo dot com and I'll send it on. (It's a secondary email for me, so the reply might be slow, but I will reply.)

I am a technology coordinator for a special education service agency and so have some experience with assistive technology. Step one is find a local assistive technology (AT) library in your region so you can borrow and try different devices and/or software mentioned here. Most states have these libraries located in various regions. Next, I suggest trying some free software. If you search, I am sure you can find a freeware screen magnifier (I know I have used one with students before). Another suggestion is to modify the normal.dot template in Word or create a Word Template as a shortcut on the desktop (with large icons of course) to a special use template. Use contrasting background/text colors and a large size font. The best color combination depends on the user, but a classic is blue/black background and yellow text. If you are looking at screen readers or other text to speech, I suggest first downloading ReadPlease. This is a freeware reader with a pay version and a pay IE addin available. The website is http://www.readplease.com For the free version, you can copy and paste in text and have it read aloud. Not great, but a good place to start. For a much more expensive investment, though probably worth it if reading is a probblem, is Kurzweil 3000. This program is simply amazing. You use it with a scanner: it can scan in any printed text and then parse out the text to read it aloud. You can zoom in to increase size of images and text. A trial is available on the website at http://www.kurzweil.com Again, your best bet is to work within your school system to access an AT library or find other solutions. If the child is receiving services as an exceptional child (special needs) then Medicare may cover expense of some devices.

My suggestion would be to aquire a small LCD or DLP projector. You could use this to project an image of almost any size. It's very easy to take a map and project it onto a wall as a 9ft by 9ft image. These projectors have shrunk considerably over the years some are smaller than a shoe box.
Local Library: These projectors have dropped considerably and you could probably pick one up used for a few hundred dollars.
Most local libraries have these projectors for either guest speakers or to show movies. It is very possible that someone might actually let you borrow one for a few weeks.
Hope this helps.
At work we use a digital projection system to project paper documents (in fact anything which is not a transparecy/viewgraph) onto our projection screen in the conference room. With good optics you can zoom in quite a bit (we once blew up a nickel to 6 feet across on the screen) - this would work well for good paper maps or any other document you would want to enlarge and/or zoom in. The size of the wall you project onto is your limit - and your wallet, since you also need a good projector.
This is where the school district may come in. The parents may be able to get them to buy equipment like that - especially since it could be used for general classromoom instruction as well. I realize, this would not help at home ...
Another comment pointed out the child's Individualized Education Plan (IEP), where this would have to be dealt with. A word of caution: The Individuals with Disabilities Education Act (IDEA) gives parents of disabled children a valuable tool for working towards a decent public education for their children. However, to get adequate education for your child, you need to become an advocate for that child. That means you need to know the law (including case law up to the Supreme Court, if you are unlucky) and the technical/medical possibilities and ramifications better than any representative of the school district you will face. Remember, you want the school district to provide a service for which they have to pay extra (equipment, personnel, transportation, etc.), and they will want to make it the least expensive for them. You think I exaggerate? My own child is severely hearing impaired, and I will have to sue the school district in order to get adequate service. What was offered us so far is so woefully adequate that I would call this neglect, at best. We live in a huge (read: resource-rich) district, so this could far and take long. Fortunately, your mileage *will* vary greatly. But dealing with IEP's/ ARD's and all the "fun" issues surrounding special education for your child does take a *lot* of work and energy - at a time when you want - and should - devote your time to raising, helping and educating your child.
Parents schould educate themselves well, if they have to take this journey. Start with Wrightslaw, a really excellent resource (www.wrightslaw.com).
Best of luck, I know what it's like!
Do your own thing. And overdo it!
I would mod parent up, but I don't currently have mod points. However, it is the same suggestion I would suggest.
For a family with a near-blind kid, a $1000-2000 projector should be in the budget. (Cheaper than most medical procedures.) It might allow the poor kid to even do other things like explore the Internet. Some projectors are extremely bright and have a very high contrast ratio - very useful for trying to make things easier to see.

The technology exists to convert printed images to a tactile format. You print the image onto special paper and then run it through a heat machine similar to a laminator. The heat causes the paper to puff up everywhere black toner is present (Google for 'tactile image enhancer' for the geeky details of why it works).
At any rate, you end up with a map that the child can feel.
Repro-Tronics is one company that can provide you with the supplies you need. We've used this technology with low-vision clients and it works well. Contact any of the Vision Services staff at The STAR Center for more information about this technology. They may also have other suggestions for you.
Don't make efforts solely to improve the child's environment. You must also help improve his sight, which is possible in spite of what top-notch doctors already told him.

Try to print diagrams with a Solid Ink color printer Such as the Xerox Phasers You can probably get a refurbished one at a good price the 840, 850, and 860 models come with free black ink for the life of the printer (So you don't need to go on Ebay and Buy Free Black ink for $10 and think you got a good deal (Man Stupid people)). The reason is that Solid Ink printers natually print with little bumps on the printer. So say you do the map using 4 Different patterns Horizontal Stripes, Vertical Strips, Just white Paper and solid fill. That way the child can actually feel the print on the paper and get an idea where things are.
This is a Mid Level Tech solution that is not going crazy plus the family gets a good quality printer.
