Sketching for knowledge capture: a demonstration

ABSTRACT

Many concepts and situations are best explained by sketching. This demonstration will show the key ideas underlying sKEA, the sketching knowledge entry associate, a system we have built for knowledge capture via sketching. In particular, we will demonstrate

• How glyph bars and blob semantics are used to sidestep the need for recognition of visual symbols.
• The use of qualitative spatial reasoning to provide richer visual and conceptual understanding of what is being communicated
• How arrows are used to express domain relationships
• The use of layers to express within-sketch segmentation, including a meta-layer to express subsketch relationships themselves via sketching
• Using analogical comparison to explore similarities and differences between sketched concepts.
