Binary Keyboard
Proof of concept for entering text by recursively bisecting a QWERTY-ordered character set.
The full QWERTY layout stays in fixed positions. Remaining candidates are shaded by group; eliminated keys disappear.
- Up selects the plain (white) group.
- Down selects the shaded (dark) group.
- Back undoes one choice, or exits from the root.
- Confirm inserts a space.
- Left front button deletes a character.
- Right front button toggles case.
A character is committed automatically when only one candidate remains. This is a standalone interaction experiment, not yet a reusable text-entry component.
