The translation is not reliable for maths beyond simple symbols in UEB (+, -, ×, ÷, /, =, <, >, ~). However, Paige Connect should reliably record the braille input which can then be downloaded as a BRF file.
We are excited that progress is being made on open-source maths translation by MathCAT! Should braille input be added to MathCAT we will ensure this is made available through our translation tool.
