Sketching for Knowledge Capture: A Progress Report
In: DTIC (2002)
Abstract: Many concepts and situations are best explained by sketching. This paper describes our work on sKEA, the sketching Knowledge Entry Associate, a system designed for knowledge capture via sketching. We discuss the key ideas of sKEA: blob semantics for glyphs to sidestep recognition for visual symbols, qualitative spatial reasoning to provide richer visual and conceptual understanding of what is being communicated, arrows to express domain relationships, layers to express within sketch segmentation (including a meta-layer to express subsketch relationships themselves via sketching), and analogical comparison to explore similarities and differences between sketched concepts. Experiences with sKEA to date and future plans are also discussed. ; The original document contains color images. Published in the Proceedings of the 2002 International Conference on Intelligent User Interfaces held in San Francisco, CA on 13-16 Jan 2002.
