Resources for Visually Impaired Maths Students
This site aims to be a place for visually impaired maths students to document resources and tools which have helped them to access their studies. The information provided here has been contributed by VI students and people who have supported them. It is hoped that this will allow new students to explore possible methods to access their studies. It is not intended as a substitute for expert advice from a disability service. It is intended only as an informal way for students to document what they are currently using.

General Information about this Project
How is Information Organised?
In the section Catagorised Links some of the items have been grouped to make it easier to find what you are looking for. In the section Entries all items can be found in no particular order.
How to Contribute
At the current moment, if you would like to contribute please email jxb1321@alumni.bham.ac.uk. Please give as much detail in your email as possible. No personal information about you will be published.
Combatting Out of Date Information
By the nature of this page, some of the information is bound to be outdated. This is because this page documents what students have used in the past. The reader should be warned that information might not be current. We are making plans to combat this issue in the future. However, the page is still useful to see how other students have/are working.

Useful for New Year 1 Students
As a new year 1 maths student, the following advice may be particularly useful:
Accessable Textbooks/Lecture Notes and Where to Find Them
This section contains advice about finding accessable resources.

Latex
What is Latex?
Latex is a tool for producing typeset documents like textbooks and lecture notes. Latex is very commonly used by Mathematicians to produce typed documents containing maths. It works like a programming language. You write a .tex source file in latex code and then run it through a program to produce a pdf. When we say that latex is accessable we refer to the source file and not necessarily the output.
Why Might it be Useful?
Unlike PDF or HTML files, .latex files(.tex format) are written in plain text. This means it is easy to read with a screen reader and text editor. It is very likely that lecturers produce their lecture notes and problem sheets in Latex and this might be a convenient way to get accessible course resources. Additionally, it is easy to write your own Latex to produce documents to communicate mathematics with sighted peers in a format they are used to. There exists programs to turn some Latex files into braille also. However, I do not know much information about how well this works.
Latex-Access Project
The Latex Access Project provides tools to make reading Latex documents with a screen reader or braille display easier. For example, a matrix navigator and proper spoken formulas. The Latex-Access Project can be viewed at https://latex-access.sourceforge.net/.
Arxiv
Arxiv is an online repository of Mathematics and Physics research resources. For example, papers and lecture notes. Arxiv stores the vast majority of it's resources as .tex latex files as well as PDF and sometimes HTML. You can visit the arxiv at https://arxiv.org. To download the .tex versions go to the other formats link and then the download source link. The files download without a file extension but they can be opened in a standard text editor like emacs or notepad etc.
Emacspeak
Emacspeak is a screen reader extension of the text editor Emacs. Whilst Emacs and Emacspeak can be technical to setup they can be a very useful tool to access mathematics through Latex and computer programming. Emacspeak is particularly useful on the mac as there is a lack of accessible text editors. Furthermore, emacs has many extensions like a calculator and calendar which are made accessible with Emacspeak. You can find out more about emacspeak at https://emacspeak.sourceforge.net/. You can find out more about emacs at https://www.gnu.org/software/emacs/.
Org Mode
Org mode is a mode for Emacs. It is similar to markdown. It can allow someone to write documents in plane text and export them to PDF and HTML files. The Mathematical input for org mode is latex and so is not a huge learning curve if you already use latex within Emacs.
Blind Math Mailing List
BlindMath is a mailing list/website where people can discuss all aspects of blindness and mathematics. View the archives for lots of discussions on a number of topics. Register on the mailing list to ask questions. You can view the webpage at http://www.nfbnet.org/mailman/listinfo/blindmath_nfbnet.org.
Desmos Audio Plotting
Desmos is an online graphing calculator. By pressing Alt-T Desmos allows you to audio plot a graph you have previously entered. Type in an expression, press Alt-T and then use the arrow keys to hear the graph. It can also tell you useful information about extrema, intersections of curves etc. You can visit Desmos at https://www.desmos.com/calculator.
Pin Boards
Pin boards are a technique to produce tactile diagrams. They can easily be DIY in a pinch. The idea is, you use thumb-tacks and elastic bands to produce diagrams. For example, with a cork-board one can place 4 thumb-tacks and use elastic bands to make a square shape. This can be used to produce shapes, plots, and graphs easily. You can buy cork boards which are small and portable for this purpose.
German Film
German film provides a way to make tactile diagrams quickly. On a rubber mat, a piece of german film is placed. German film is a little bit like clingfilm but thicker. The film can then be drawn on with a stylus. The result is a tactile diagram. German film can be bought in a number of places. Try the RNIB shop. Your university might buy it for you.
HTML Files
HTML files can be produced from Latex source files. If you struggle to read the raw latex file, HTML files can be used and screen readers often read out the Mathematics in a more friendly way. This website is an example of an HTML file. Some sample maths is given below: \[ 4\int_0^1{ \sqrt{ 1-x^2} \, dx} = \pi. \] Don't worry if that didn't read properly with your screen reader. On Mac with Voiceover it should have automatically read out properly. If you are using NVDA you might need to install a program called Mathplayer4 to get it to work properly. Please consult the instructions for your screen reader. If you use NVDA see Setting Up NVDA for Mathematics.
Setting Up NVDA for Mathematics
You can read the section of the NVDA instructions for setting up NVDA to read maths at https://www.nvaccess.org/files/nvda/documentation/userGuide.html#ReadingMath. NVDA also allows you to navigate through the mathematics you are reading and examine it in small chunks. This might be a good way to access lecture notes through HTML Files.
Microsoft Word for Producing Mathematical Documents
MS Word is a program for writing documents. It has a feature which allows one to enter equations in a number of formats, including Latex. Writing an entire Latex document can be quite complicated. MS word can therefore make it easier to write out problem sheets and other mathematical documents. You can also save your documents as a PDF.
Open Textbooks | American Institute of Mathematics
The Open Textbooks page by the AIM can provide some books in accessible formats. Some of the books on this list have HTML versions and some of them have .tex versions. They are all free to access. They are not all accessible. You can find the list of books at https://aimath.org/textbooks/approved-textbooks/.
