summary

Animated alphabets called Livefonts are built as colored block + motion combinations, chosen by a crowd-sourced perceptual survey (50 MTurk workers giving 5,386 evaluations) and an optimization (branch-and-bound) that produces two candidate 26-letter sets. A controlled lab study (25 participants: 10 low-vision, 15 sighted) shows the best Livefont reads at roughly half the area of Verdana, outperforming prior static smartfonts, and a web training study finds comparable learnability after 2,000 practice questions, with some individuals reaching parity with Latin speeds.
