DraftMarks embeds process traces directly into the document using skeuomorphic encodings (e.g., masking tape, smudge marks, eraser crumbs). Instead of external provenance dashboards, the process becomes legible in situ during close reading. This supports what we call process-aware reading.

As AI becomes a writing collaborator, readers face a new problem: what is human thought? What did the AI produce? Existing disclosures tell us that AI was used, but not *how* collaboration unfolded. We introduce DraftMarks, an augmented reading interface for human–AI co-writing. #CHI2026

🤔Giving complex tasks to AI agents is easy—getting them to do exactly what you want isn’t. How can human-AI collaboration give us more reliable & steerable agents? 🍫Introducing Cocoa, our new interaction paradigm for balancing human & AI agency in complex human-AI workflows. 🧵

A screenshot of the first page of an academic figure with a list of authors and a high-level schematic figure describing Cocoa, an interactive system for co-planning and co-execution with AI agents.

#CHI2024 Paper: Using tools like ChatGPT can feel like the Hot-or-Cold guessing game, finding the right prompt to get the response you want! We examine the cognitive challenges people face in translating their intentions into prompts and make recommendations for Generative AI app designers

Screenshot of first page of paper showing the teaser figure. figure is : A conceptual diagram of gulf of envisioning in the form of a 3D cube with x-axis is labeled "Functional Flexibility (F)", ranging from "predetermined" to "dynamic", and the y-axis is labeled "Output Determinacy (O)", ranging from "definitive" to "stochastic"and the z-axis "Intent Specificity (I)", ranging from "well-defined" to "ill-defined" The figure shows three points one close to the origin depicting tradtional interfaces such as calculator, one at extreme indicating AGI that understand goals, and a third point in the middle indicating envisioning specific intentions.
