I don't understand why/how some of the changes they've made would help dyslexics immediately. Perhaps you could explain.

It seems like most of the changes were arbitrary (e.g. rotation, making the lower parts bolder) and designed to make two otherwise similar characters distinct. Wouldn't that require a learning period, to figure out which characters were changed in which ways? If you don't know (reflexively from memory) whether they rotated the `i` or the `j`, the rotation won't help anything.

In the video, they explain it as embracing the conception of the letters as being 3d objects. The added weight in the lower parts would intuitively anchor that letter in that orientation. Perhaps a 'j' should be tilted due to its asymmetry.

As for my $.02, I think the mix-ups often occur in real-time due to proximity. Making the symbols distinct would perhaps lessen the likelihood that the brain will try to identify those conceptual objects as a unity when they are near one another.
