I've sailed the open oceans with a blind man at the helm. Which sounds like a line from PoTC but really: he used an audio compass that played a tone at different points of the compass, higher or lower so he knew how to correct. The rest was done by feeling the way the boat handled through the deck and the wheel.
- binarymax 16y ago
  The compass tones are ingenius, but aside from that I'm not surprised he was able to do this as sailing is one of those things where feeling plays a much larger role than one would expect. There are many forces at play that have nothing to do with sight. Having helmed in night storms of 20 foot seas where I could basically see nothing, the motion of the vessel and feedback force exerted on the wheel, I quickly got a sense of how the boat was moving. In fact in those situations I probably would have been much better off with your friends compass than the soaked one at the wheel. And dont even get me started on trying to read the windex in such conditions! Coding blind would be much different. The input is physical but there is nothing tangible coming back. It is more or less all visual. Come to think of it, if I ever lost my vision I would probably become a full time sailor :)

    I went to school with a blind CS student. He had no problem using a computer by himself but the normal classroom setting was vary difficult for him. Based on how he operated meetings would be far more difficult than actually writing code. PS: Ok, his is not going to be building a GUI but text to speech works well. And a keyboard only interface works fine for both VI and visual studio.
    - pavel_lishin 16y ago
      Why were meetings more difficult than writing code?
      - Retric 16y ago
        The tendency of people explaining their ideas to draw diagrams on paper / a white board. Once a diagram was on a computer there are tools to help him understand it, but it took a while. So, the only way for him to keep up with a free flowing discussion is to follow what people said.
        gcheong 16y ago
        I remember looking into whiteboard systems that automatically digitize what people write as a way to conveniently record what was written but the implication that this tech could also be used to help a blind person during a meeting is interesting.

    > The input is physical but there is nothing tangible coming back. It is more or less all visual. Not really. At the end of the day it's just data, text, how you encode it is not very important as long as it can be understood. Because humans very strongly rely on sight, it makes sense that the default serialization format for text output be print/visual, but there are a number of non-visual interfaces to text. And if none fits, build a new paradigm. I think samlittlewood below makes a good point: even with a fairly slow (e.g. braille) output, it's at worst similar to coding using a line-oriented editor (e.g. ed). Except you're used to it because you see pretty much everything via a line-editor so you're probably proficient at it.

  I'm a blind programmer. I use a 80-character braille display which shows one line of text at a time. My preferred language is Python although some blind programmers dislike it for its syntactic use of indentation. I find that scrolling with the braille display and feeling for the indentations on left gives me a good feel for the shape of a program. I know another programmer who prefers Perl because of its rich use of sigils, although he uses speech synthesis. I prefer to use vim for all types of editing (I hate IDEs although many blind programmers like Eclipse or Visual Studio). Why do you reckon the feedback blind programmers use as non-tangible BTW?
  - gaius 16y ago
    What do you think about languages like J or APL or even Haskell, where you can do an awful lot in very few characters?
    - eney 16y ago
      I don't know APL and I'm not currently smart enough for Haskell. My current infatuation for learning is with Scala. When I first started programming in the mid-80's, I was hacking on a COBOL stock-control system on VMS; the braille display I was using at the time didn't do terminal emulation, and this software built screens by outputting VT52 escape sequences. Although I learnt to decode them so that I could check my screens for alignment and spacing etc. I discovered that I could log an interactive session using SET HOST/LOG; I wrote a TECO program to translate these sessions back into a 2-dimensional layout that was much easier to read on my braille display. So, yes I generally like dense languages.
      - viraptor 16y ago
        > "I learnt to decode them so that I could check my screens for alignment and spacing etc." That's just amazing, but I guess it makes a lot of sense... since your display is not 2d-based in the same way as standard screens are and you can read the code itself (i.e. the display is consistent). I'd upvote you a thousand times just for how cool it is to workaround difficulties in so leet way :) Of course it also reminds me of... I don't see code, just blondes, brunettes, redheads...
- jkent 16y ago
  How did he handle other users of the ocean?
  - gaius 16y ago
    No worse than any other helmsman :-) Which is to say with the boat heeled over or the jib up, the helm is reliant on the bowman and the rest of the crew keeping watch anyway, you can't see much forward.
jms 16y ago
It's interesting how quickly the text to speech setup can be made to run. My dad's computer talks so quickly I can't understand without slowing it down.
samlittlewood 16y ago
How similar is this to using a line editor (ed/edlin/edit/teco) on a slow terminal? You have a model in your head, code in a buffer, and you use the edit commands to update both - with occasional listing sanity checks to check you are keeping the two in sync, or move to a new region. I hear some guys wrote a pretty cool operating system like that!
- Someone 16y ago
  It is somewhat similar, but to get the real 'feel', you should also limit your line width to one to two characters. Braille reading typically is done with both hands (with one looking ahead, and one doing the actual reading), so it does 'show' slightly more than that, but you will still be faster at reading those characters than a blind person would be. Also, you would have to give up syntax coloring and style and font variations. Finally, chances are that some characters (braces, asterisk, plus sign) from your programming language take up more than one braille character. Real nerds would hack their character-to-braille pattern translator to optimize that translation table, but the price you pay for that is that you will have to cope with multiple mappings. Actually, you would have to do that anyways, as there is disagreement about the encoding to use, even for digits, and because the U.S. frequently uses a contracted braille system (where, for example, the single-letter word 't' must be read as 'the' where appropriate; that 'where appropriate' is for the reader to guess at)
  - Avshalom 16y ago
    Also, you would have to give up syntax coloring and style and font variations. I'm pretty sure ed was dead by the time those were invented, the wiki claims the "one of the first" syntax highlighting editors was in 85.

Amazing. It's really hard to imagine programming blind and jumping between methods/files/debuggers/browsers effectively, but it seems some people do pull it off. I was struggling with tendonitis in my right arm a year back and had to do all my coding left-handed, and that made me feel crippled and annoyingly slow. It's really impressive what people can overcome.

We had a blind classmate all through my undergraduate program in CS, and he was a very capable hacker. He lived inside emacs using emacspeak with a high speed synthesized reader voice, and you could often hear his terminal talking to him in the front row if you listened carefully during class. Blind people develop good memories because they are constantly building detailed mental models of spaces they need to navigate, and I think this might give them a leg up programming because they are used to working with mental models rather than referring to maps, diagrams and documentation. Their are obvious drawbacks, but I think programming is probably a pretty good choice of profession for blind people.

  I've used Graphviz to make relationship diagrams to aid my communication with sighted people. There's an interesting Google Developer Podcast with T.V. Raman where he mentions programming directly in Postscript while he worked at Adobe. I've used LaTeX for my personal documents (CV etc.) and sighted people have asked me how on earth I managed to produce such a nice document. I wonder how feasible it would be to use Metafont for more intense graphical expressions.

There are plenty of 'impossible' things you can do blind. For example, there are blind golf players. They have their own golf associations and tournaments. One of my old co-workers used to assist blind golfers by describing the location, distance, etc. The golfer does the rest.

I've used Graphviz to make relationship diagrams to aid my communication with sighted people. There's an interesting Google Developer Podcast with T.V. Raman where he mentions programming directly in Postscript while he worked at Adobe. I've used LaTeX for my personal documents (CV etc.) and sighted people have asked me how on earth I managed to produce such a nice document. I wonder how feasible it would be to use Metafont for more intense graphical expressions.

A group of students from Southern Illinois University Edwardsville and Washington State University is working on a programming language for the blind: http://www.youtube.com/watch?v=lC1mOSdmzFc http://www.youtube.com/watch?v=lC1mOSdmzFc

I know a blind python programmer Krishna kant Mane[0], who works with pylon, is a FOSS evangelist, leads a foss project GNU Khata[1] and an awesome speaker[2]. I loved the way he uses all free and open source tools to work on his laptop, program and deliver. Hats off.

I wonder how useful would be a VoiceOver-optimized editor for iPad.

There are plenty of 'impossible' things you can do blind. For example, there are blind golf players. They have their own golf associations and tournaments. One of my old co-workers used to assist blind golfers by describing the location, distance, etc. The golfer does the rest.

One of the lead programmers of JAWS is Glen Gordon. He is blind is one of the smartest programmers I have known. http://en.wikipedia.org/wiki/JAWS_%28screen_reader%29 http://en.wikipedia.org/wiki/JAWS_%28screen_reader%29 http://www.afb.org/afbpress/pub.asp?DocID=aw070204 http://www.afb.org/afbpress/pub.asp?DocID=aw070204

I suggest the person asking this question to watch "Sneakers."

Are there any other HNers out there with other disabilities that cause you to modify how you interact with your computer or how you program?

I always wanted to learn braille as a kid so I could read in the dark.
