ELLABraille maths: UEB technical notation
ELLA writes maths and science in UEB technical notation. This is the maths code inside Unified English Braille. ELLA does not write Nemeth code.
What works best
Equations that exist as equations, not as pictures, give the best results. Word equations, LaTeX files and web pages with MathML all keep their structure. ELLA can also recognise supported equations on PDF pages, but recognition from a page is less certain.
If you have the original, upload that rather than a PDF.
What to ask for
- "Braille with UEB technical for the maths."
- Say the grade for the prose around the maths. See grade 1 and grade 2.
- Name the page width, such as 32 cells and 25 lines.
UEB technical notation is written in grade 1 style, so the maths itself is not contracted.
What to check
The terms of service name maths and science notation as a place to take special care. Check:
- every equation, one by one, against the original, whenever the braille will be embossed or the maths matters to the answer;
- fractions, roots, powers and subscripts, where the nesting matters;
- chemical formulae and units;
- anything ELLA flagged in the reply as not read reliably.
A braille reader who knows the notation should do this before the file is embossed.
Diagrams, graphs and charts
ELLA writes a description of each diagram, graph or chart in braille. Check every description against the original figure, because a description can miss detail that matters for the maths.
If an equation is wrong
Name the braille file in the conversation. Say which page and line is wrong, and what it should be. You can also contact support with the conversation link. See braille looks wrong.
