In this position paper, we review the latest findings in bio-inspired and cognitive studies in diagrammatic engineering sketch understanding in the Visual Design and Engineering Lab (VDEL) at Carnegie Mellon University. We discuss issues including (i) image-based recognition of off-line sketches with a bio-inspired visual pipeline, (ii) the stroke-image duality of online sketches and (iii) a cognitive model of human sketch recognition. We present our position of their implications for future sketch understanding research.
