The project is to design a Chinese font library based on the open source fonts as the frame structure, and form a design research report. Based on the report, the project will develop an open source AI font design platform. When users design the font on the platform, after adjusting any stroke of a certain font, all related character glyphs will be automatically adjusted accordingly in real time to achieve the design effect of " The slightest nudge causes the widest chain reaction ", thus countless new fonts can be developed with smart and high-speed design. The platform can support multi-person collaborative design and accommodate 10,000 people for real-time online design at the same time.
