q3 · i? · qualitative · r?

Study 2 (N=16, within-subjects V1 vs. V2) qualitative results: V1 users felt uncertainty (P5: "not clear if the system accurately captured my range"), while V2's instant alignment let participants ask "with trust" (P6). The authors interpret this as mitigating the Gulf of Execution.

"Participants reported that Content Snapping provided immediate visual confirmation of their intended referents, bridging the gap between action and system perception."

Related Claims¶

• Unmediated pen input introduced new pen-specific barriers: lack of visual feedback on referential intent and high interaction cost of handwriting complex queries — related
• In Study 1, learners preferred Penquiry V1 for part-scoped, specific-target and short questions, and favored the baseline for general topics and longer interpretive questions — related
• Learners using standard keyboard-based LLM workflows during pen-based study face a Referential Barrier and an Expressive Barrier — related
• Pen input supported deictic referencing: 85% of V1 queries contained at least one visible pen mark, and ease of referencing improved significantly over the baseline — related
