how many blind and visual impaired people use computers with assistive devices

I also want to know how many people cannot use computers without such assistive devices (Tactile or auditory aids).

I have some problems with understanding the definitions and its
consequences.
I read that to be legally blind in america means seeing worst then 20/600
with your best eye, but I don't know what that means in reality.

can legally blind people read a very large letters (like using computer with
magnification software), or they are usually have to use other methods.

or in other words - how many people may need special tactile devices, in order to use computer?

how many blind and visual impaired people use computers



Here’s an answer to part of your question. Regarding how many blind and visual impaired people use computers with assistive devices...

As of 1999, the total number of people ages 15 and older with any "limitation in seeing", who report they have access to the Internet, is just over 1.5 million (1,549,000). The total number of people ages 15 and older, with a limitation in seeing, who use a computer regularly is a bit under 1 million (979,000). There are about 196,000 people with a *severe* limitation in seeing who have access to the Internet, and about 102,000 persons with a severe limitation in seeing who use a computer on a regular basis. (See Gerber and Kirchner, in press, JVIB, March 2001, volume 95, issue #3).

So, Uri, while the data source does not specifically cover the use of assistive devices, our best estimate is that those people who comprise the "severe limitation in seeing" group probably are using assistive devices, plus an undetermined but probably small portion of others with some "limitation in seeing, not corrected by ordinary glasses."

These data come from the 1999 "Survey of Income and Program Participation" (SIPP), conducted by the Bureau of the Census.

More information on rates of computer use can be found in the (forthcoming) March 2001 issue of Journal of Visual Impairment and Blindness (volume 95, issue #3). See USABLE #7 (Using Statistics About Blindness and Low vision Effectively), entitled "Who’s Surfing? Internet Access and Computer Use by Visually Impaired Youth and Adults" by Elaine Gerber and Corinne Kirchner.


p.s.



I forgot to mention, if you have any questions about this, you can email me directly at: gerber@afb.net




The question posed included a request for clarification about the definition of "legally blind" in America. I can deal with the technical part of that -- which is to say that what the questioner has heard is incorrect. The U.S. federal definition is that legal blindness applies to someone with visual acuity of 20/200 or less in the better eye with best correction, or with a visual field of 20 degrees or less. That does include people who can see very large print from close up. In terms of applying that to the definitions used in the survey that Elaine Gerber referred to, it is similar to the group who are identified as having "severe limitation in seeing" because they report they are unable to see words and letters in ordinary print, even with glasses.
Hope this helps.

How many blind use computer's.



Hi, i am a 48 yr old man who can use a computer iam totaly blind but it was not easy,i had to go to a blind school and learn to do this.if you ever need a friend write to oklahoma482_1@netzero.net


FYI - legal blindness acurately defined



The two definitions most quoted for legal blindness here in the US is 20/200 corrected vision in the better eye or a visual field not extending beyond 20 degrees in the better eye. There is actually one more. It is that your visual efficiency is no more than 20 percent. To get this figure you multiply your visual field percent by your visual acuity percent. For instance, if you have an average visual field of 25 degrees (40 percent field remaining) and have 50 percent visual acuity then you have a visual efficiency of 20 percent so you would be legally blind.


Re:how many blind and visual impaired people use computers with assistive devices



hi Uri or to anyone else who reads this,
My name is rachel and I am 14 yrs of age and legally Blind. I use a computer with assistive programming. The computer talks to me and tells me what is on the screen. I have a disease called juvinille Macular Degeneration. It is one of the most common eye diseases that cause blindness. In order to be called "Legally Blind" you must have an eye acuity of 20/200 or 20 degrees of your side vision. When I say 20/200 all I am refering to is that me being legally blind can see an object at 20 ft and normal sighted person can see that same object at 200 ft. But my vison is much worse than that. my eye aquity is 20/500. so if you can see something at 500 ft I have to be 20 ft to see it. My mother told me that in order to be in the catagory of legally blind your vison must be between 20/200 to 20/600 and after that your blind. okay I hope you understand. Good luck! If you have any questions e-mail me at Ladynoitall@earthlink.net


Re:how many blind and visual impaired people use computers with assistive devices



Hey. I'm totally blind. I'm 16 years old and I became blind when I was 8. If you have seen the movie Daredevil I
became blind the same way the charactor did. Chemical spilt into my eyes and that was it...I am going to be blind
for the rest of my life. It was hard for me at first because I was young and didnt understand what was going on.
I couldnt see at all. My hearing became sharp and so did my nose. I use a walking stick to help me get around.
I go to a normal public highschool. I always went to a normal school. But after schools when I was younger
I would go to a blind school for a few hours with my mom and they would teach me how to read brail. I wear
sunglasses whenever I go out to places. I have best friends and I have no clue what they look like. I remember
what my family looks like but I forgot what I look like. I remember one day my mom came home with a totally new
hairstyle. She even got it highlightes. I cried because I wanted to see what it looked like..I wanted to see what she
looked like. I wish I knew what my hair looks like. All I know is that it's blond and short. I use to play soccer
but now I cant anymore. I want to be a vet but I dont know if thats possible. For my computer I have a special one.
My keybored has brial on each key for me to feel. But I dont need it anymore because I memorized where each
key is. When i'm chatting to comeone on my AIM it talks to me saying what they sent. Or if I'm surfing the web
it talks to me saying whats on the page. I hope that I helped you out. And if you have any questions then plz ask and
I will be more than happy to answere you.


Re:how many blind and visual impaired people use computers with assistive devices



Hey, I have 20.4000 vision with no depth perception. I am learning braille on my own because I don't know if I qualify for hadley. Their is a braille class offered throught my local college (online couse), it's a beginning braille couse. I already know beginning braille but it goes into some of the contractions also. My anxiety is that I won't be able to keep up with the work. Do you think if I got a note from my eye-doctor I could get into Hadley?

Re:how many blind and visual impaired people use computers with assistive devices



Earlier this year, Svetlana started a memorial project to her father, theoretical physics professor M.N. Adamov of St. Petersburg, Russia, 55 years at St. Petersburg State University, to help blind students and professors and teachers of blind children in Russia.

The late Prof. Adamov wrote or co-wrote more than 100 papers. He was blind from the age of 2. There is no stipend, assistance or support for blind students now in St. Petersburg. We are assisting with used computers, voice synthesizer and screen reader devices, and Braille display units. If anyone is going to St. Petersburg or Moscow, we have something for them to take to blind people.

Thank you.

may need a special tool so that people can use computers like normal people, let's hope there are new methods for using computers for the blind.

The late Prof. Adamov wrote or co-wrote more than 100 papers. He was blind from the age of 2. There is certainly no stipend, assistance or assistance for blind students now in St. Petersburg. We are assisting with utilized personal computers, voice synthesizer and display reader devices, and Braille show units. If anyone is going to St. Petersburg or Moscow, we have one thing for them to take to blind people.
