Summary
This is one of the early papers in free-hand sketching. It presents the HUNCH system, a set of software programs that process a sketch in order to advance towards a general sketch recognizer. The work does not focus on a particular domain but rather tries to explore techniques that may work for several domains. Amongst these techniques they explore corner finding, latching, use of context and over tracing. Many of this properties are now of common use in sketch recognition. This paper emphasizes in heavily involve the user towards the agreement on the machine interpretation in contrast of having a fully automated machine that probably does not really reflects the user intentions.
Discussion
This paper was published in 1976 yet it already covers many of the aspects of preprocessing in sketch recognition that are widely used today. For instance the corner finding algorithm used by STRAIT is very similar to the one presented by Sezign in 2006 as they use curvature and speed. Although the paper is rather general and does not go really deep into specifics, solving the problems found in recognition, its early publishing date most likely inspired many of the papers that were published recently.
