Yeah, it's a telling point that when we're asked to read passages of Dotsies, the font's sized up least three times (36px to 42px)—and so at least nine times the screen area taken—compared to the base 13px size used in the "How much better is it?" example. You're going to need damn good eyes to read Dotsies at anything like 13px, and I suspect even the sharp-eyed are going to misread a lot. Size Dotsies text up to the point that people of average vision can read it as reliably as a normal font at a reasonable size, and I don't think you're going to get much, if any, greater information density. I'm reminded of Speedtalk, a language from Robert Heinlein's story "Gulf", which had every combination of phoneme and delivery (pitch, length, etc.) represent a word in the Basic English vocabulary. So, every spoken "word" in the language is actually a full sentence. But, it takes intense futuristic training just to be able to speak vaguely intelligibly in it, because all the normal imprecisions of speaking (much less speaking in a new language) take any tiny error from "You used 'record' as a noun, but with a long 'e' and the stress on the second syllable." to "You have a hovercraft, and it's full of what???" Now imagine trying to follow speech in such a language if the speaker's out of breath, alarmed, surrounded by background noise, etc. Just not enough redundancy for reliable communication.
