DejaVu High Legibility ("DejaVu HL") font

DejaVu HL is an ongoing effort to develop a free high-legibility font for science courses. This serves 2 purposes:
  1. Decreasing student confusion due to lookalike glyphs (e.g. is CH2Cl2 the formula of dichloromethane or 1,1-diiodoethene?) (Yes, that's a real-life question.)
  2. Improving comfort for students with reading disorders (in particular dyslexia).
Background: I looked into employing a high-legibility font, but failed to find any freely available options. Furthermore, some of the generally available fonts that are deemed "dyslexic-friendly" have very incomplete unicode support, complicating the use of Greek and mathematical glyphs, which are ubiquitous in science. Therefore, I created a variant of DejaVu (itself an unicode expansion of Bitstream Vera) with a strong focus on legibility.

Installation and usage

Sample text: creation of DejaVu HL

My primary goal was to obtain a proportional sans serif font, but with serifs on glyphs that would otherwise be poorly distinguishable. Specifically, my starting point was DejaVu Sans, to which I added select glyphs from DejaVu Sans Mono, a monospaced font that is optimized for programming (where confusion between lookalike glyphs can have disastrous consequences) and therefore already contained the desired serifs on glyphs that might otherwise be ambiguous. The laborious part consisted of tweaking the shapes and character spacing of the imported monospaced glyphs, as to make them look less foreign in a proportional font.

Interactive 2D van der Waals gas simulation


To the right of this text is an interactive 2D simulation of a van der Waals gas. The following is a "standalone" link that will adapt to different screen sizes (and is therefore more useful for general education purposes):

The simulation can be interacted with in the following ways:

Note: if you have a potential use case that may not be covered by the preceding statement, please do contact me using the "Show e-mail" button next to my picture. I would generally like for this to be used by the community as a tool for teaching (and potentially research). In that light, the current license is merely a placeholder for something more appropriate. What that "something" will be depends on your feedback!
