Thinkink: 2D Spatial Ink-native Interaction with LLMs
Thinkink puts the LLM directly onto a shared handwritten canvas, answering in ink-like text and sketches.
The paper frames the system around ideation with notes and drawings, where prompts can be written or sketched instead of typed. It uses a semantic tree to interpret ink and a lightweight state-machine UI to keep user control explicit. The authors built it through three studies: formative work with 12 people, a diagnostic probe with 6, and a final study with 10 on how it fit into ideation practice. ArXiv · AI/CL/LG's note
