Add Latex for Math Notations
Make sure to add latex for complex math notation if you just include a screenshot/picture of the math. Some students with visual impairments are able to read latex representations. Consider the example about TF-IDF below:
In the example, there are texts, inline math symbols (e.g., ), math equation as one line (e.g., ), arrows, and explanation. It involves many components and adding alt text to each single component can be challenging both for the authors and the readers.
To resolve this problem, you should:
- Keep your original slide (yes, regardless of how many components).
- Mark all components decorative.
- Create another white box and add alt text as LaTeX to it.
LaTeXiT is a great tool to quickly iterate on the LaTeX formula as you work on your slides.
