five moves. collect and notice grow the cube; distinguish, rotate and zoom look at it. the UI never names them — the gestures are the moves.
| move | phone | desktop | notes |
|---|---|---|---|
| rotate | swipe | arrow keys | pieces travel to their new group (300–420 ms, ease-out). a single piece stands still. |
| zoom in | tap a piece, or spread two fingers apart | ctrl + wheel | scales from the tapped tile's position. |
| zoom out | bring two fingers together (closing along the diagonal), back arrow | ctrl + wheel, esc / backspace | one step further out from where you are, even with nothing behind you. works on every screen inside another; the back arrow stays as the backup (principle 25). |
| back | goes the way you came | same | the back label names the screen you came from. |
OLAP equivalents: slice, dice, pivot, drill down, roll up. OLAP has no name for collect, notice or distinguish.
the words are zoom in and zoom out, never "pinch": everyone knows how to zoom on a phone, while "pinch out" and "pinch in" are heard the opposite way round.
