TriageDeck

Decisions at the speed of a gesture: fling the top card toward a decision, or use arrows and buttons — with tallies and an undo that flies the card back.

Live — this one is real

Queue

Fling the top card toward a decision, or use the arrow keys or buttons. Backspace undoes — the card flies back from where it went. Illustrative content.

Props

Accessibility

The deck is a focusable group named after the current item and its position. Arrow keys make the decisions a fling would; every decision also has a labelled button with its key, and Backspace undoes. Each decision announces what happened and what comes next. Tallies are a labelled list.

Motion

The top card follows your hand and tilts with it; decision stamps fade in as you cross a threshold, and release velocity carries it off. The next card steps forward in depth, and an undone card flies back from the side it left by. Reduced motion decides without flight or tilt.
