Rationalizer: Leveraging LLM to Support User Providing the Rationales Behind the Rating of Likert Scale Questionnaires

Surveys, especially Likert scale questionnaires, are widely used in HCI to capture users’ attitudes and experiences, but numeric ratings alone provide little insight into the rationales behind those ratings. While adding open-ended text fields or post-questionnaire interviews can elicit richer explanations, they ofte…

EvaluAId: Human-AI Collaborative Evaluation of Open-Ended Student Essays

Open-ended writing assignments are central to higher education, yet heterogeneous submissions and scale make evaluation difficult. Automated writing evaluation (AWE) promises speed but often trades away transparency and sidelines human judgment. This paper repositions AI as an on-demand collaborator that can provide s…

Synthia: Visually Interpreting and Synthesizing Feedback for Writing Revision

While recent advances in HCI and generative AI have improved authors' access to feedback on their work, the abundance of critiques can overwhelm writers and obscure actionable insights. We introduce Synthia, a system that visually scaffolds feedback-based writing revision with LLM-powered synthesis. Synthia helps auth…

Friction: Deciphering Writing Feedback into Writing Revisions through LLM-Assisted Reflection

This paper introduces Friction, a novel interface designed to scaffold novice writers in reflective feedback-driven revisions. Effective revision requires mindful reflection upon feedback, but the scale and variability of feedback can make it challenging for novice writers to decipher it into actionable, meaningful ch…

ProcessGallery: Illustrating Design Principles through Contrasting Pairs of Early and Late Iterations of Visual Designs.

Traditional design galleries enable users to search for examples based on surface attributes (e.g., color or style) while largely disregarding underlying principles (e.g., hierarchy or readability). A series of studies explored how example galleries could be constructed to help novices learn key design principles. Stu…

When to Give Feedback: Exploring Tradeoffs in the Timing of Design Feedback

Advances in AI have opened up the potential for creativity tools to computationally generate design feedback. In a future when designers can request feedback anytime on demand, how would the timing of these requests impact novices’ creative learning processes? What are the tradeoffs of providing access to feedback thr…
