Talkat NDC Copenhagen 2025 · 2025-09-08..09-12· [design-collaboration, testing]
slides:none on file

A case study tour that links concrete UI choices to real outcomes: a point‑of‑sale chips-and-pickle button that forces unwanted pickles and a mobile app truncating special requests to 25 characters; a Hawaii emergency alert system that broadcasts a false ballistic warning for 38 minutes because a live/test dropdown and no undo let a wrong selection propagate; Three Mile Island’s PORV valve misread where an indicator light shows “command sent” not valve state; and the 2000 Florida butterfly ballot that misaligned punch holes and shifted hundreds of votes.
