September 2026 HCI paper proposing that generated interfaces should also generate ways to ask users about unstated preferences. Its six-axis design space and Ditto prototype cover questions, alternatives, editable panels, and other prompts embedded in the interface, with findings from two user studies.

Why This Paper Adds New Signal:
1. Elicitation as generated UI: Makes preference discovery part of the interface instead of relying only on a chat prompt
2. Concrete design space: Describes fidelity, saliency, amount, frequency, assertiveness, and placement for asking users
3. Working probe: Ditto implements 12 elicitation techniques, including in-place alternatives and editable controls
4. User evidence: Studies found that elicitation surfaced previously unformed preferences and that preferred ways of being asked were more consistent than UI choices
