NonVisual Desktop Access (NVDA)

A free and open source screen reader (written in python) for the MS Windows operating system. NonVisual Desktop Access was started because of the need for a free open-source non-visual access solution for windows. Written entirely in python, NVDA is a functional screen reader that allows you ... [More] to use Windows without vision by using MSAA, the windows API, and a speech synthesizer to convey what is happening. [Less]

openbraille

This project only hosts some of the code of a future real project about a Braille Printer. The whole work will be open sourced. We are currently working in the firmware and driver source that is currently pointing to Linux platforms but may be expanded to work on Windows systems too. The target of ... [More] the project is to provide the circuit, pcb, firmware and driver of a braille printer, using the most simple and economics electronic components. So far there is a small prototype working. Further reference will be added in time. [Less]

jmediatype

OverviewjMediaType is a jQuery plugin that allows javascript to determine the current media type(s) in use by the user agent thus allowing you to change javascript behaviour to suit the needs of the media type(s). Example scenario: You're viewing a normal web page and choose to go in to full ... [More] screen mode after hooking up a projector. Using the "Fullerscreen" Firefox plugin the projection media type is enabled and having detected this you run some jQueries to convert the web page in to a slide show presentation. AboutI got the idea for this jQuery plugin from the following blog post: http://www.ibloomstudios.com/articles/css_media_targeted_javascript/ I noticed that the method used had some issues, most notably the fact that it's possible for a browser to report more than one media type at the same time - we can't simply use z-index and a switch statement. Currently this project is in alpha release state - I've got a rough draft of some working code, but it needs turning in to a proper plugin, events adding, etc. I'd also like to know if it's possible (from JS) to programatically change the media type. Any help greatly appreciated! Google talk screen name: guy . fraser1 at gmail . com CodeI've not got round to handing this in to SVN yet. In fact, I've not even turned it in to a proper plugin yet! But before I do something stupid and lose the code I'm just going to dump it in here first... CSS body div#atb-mediatype { border-width: 0; padding: 0; margin: 0; } @media print {#atb-mediatype {margin-top:1px;}} @media embossed {#atb-mediatype {margin-right:1px;}} @media braille {#atb-mediatype {margin-bottom:1px;}} @media aural {#atb-mediatype {margin-left:1px;}} @media tty {#atb-mediatype {border-top:1px;}} @media screen {#atb-mediatype {padding-top:1px;}} @media projection {#atb-mediatype {padding-right:1px;}} @media handheld {#atb-mediatype {padding-bottom:1px;}} @media tv {#atb-mediatype {padding-left:1px;}}HTML Detecting media type...JavaScript jQuery(function() { var foo=function() { var test = jQuery("#atb-mediatype"); var media = {}; media.print = test.css("border-width"); media.embossed = test.css("margin-top"); media.braille = test.css("margin-right"); media.aural = test.css("margin-bottom"); media.tty = test.css("border-top"); media.screen = test.css("padding-top"); media.projection = test.css("padding-right"); media.handheld = test.css("padding-bottom"); media.tv = test.css("padding-left"); test = ""; var i; for (i in media) if (media[i]=(parseInt(media[i])==1)) test += i+","; jQuery("#atb-mediatype").text(test); } setTimeout(foo,2000); });As you can see, I'm using border, margin and padding properties as simple binary registers (each capable of holding 4 bits) with each media type using one of the bits. There are several unused bits which should give some room for future extension. I'm currently trying to work out how to more elegantly detect changes in media type - eg. I might start in screen mode then move to projection mode, especially when using something like the "Fullerscreen" Firefox extension (which also results in both screen and projection media types being used at the same time). Ideally an event should also be triggered when the media type changes, but I've not used jQuery events yet. LicenseThis plugin uses the same dual-licensing model as jQuery: MIT and GPL Just choose the one that suits you best :) [Less]

braille-pt

This project is an efort to improove access to digital braille material for portuguese braille users. In an initial phase we want to improove portuguese braille support to existing braille software, such as liblouis and brltty. This way, portuguese braille users of screen readers like NVDA our orca ... [More] can have a more compiling access to braille display output. We pretend to develope a portuguese grade 2 table for liblouis (for use in NVDA, orca, and possibly other softwares) and to improove the existing one for grade 1. It is also planned to develope a table for portuguese math braille code, but because this is not a trivial task we will not start doing it for now. [Less]
