What NCKU's architecture studios, industrial design classes, and ICID taught me about treating every digital product as an intervention in a place with history.
From grids and motion to probability, optimization, and AI, design turns mathematical relationships into things humans can see, use, and trust.
Why familiar dramatic ideas can remain deeply attractive, and what narrative design shares with interaction design.
Notes from Tainan on why products, interfaces, places, and campaigns need cultural roots before they can carry meaning.
How cultural mapping can turn places, stories, routes, archives, and audiences into a living urban interface.
