SummaryThinkink is a research prototype enabling handwritten text and sketches as prompts to LLMs, with responses rendered as ink-like text and drawings on a shared 2D canvas. A semantic tree aids ink interpretation, and a state machine controls interaction. The paper reports three user studies (N=12, 6, 10) and design implications for ink-native LLM ideation workflows.
Why it mattersConcrete three-stage user study of pen-first LLM interaction, with design implications for spatial canvas tools. Useful reading for anyone prototyping drawing-based AI interfaces.
