  The "meaning" of an iconic gesture is conditioned on its informational
evaluation. Only informational evaluation lifts a gesture to a quasi-linguistic
level that can interact with verbal content. Interaction is either vacuous or
regimented by usual lexicon-driven inferences. Informational evaluation is
spelled out as extended exemplification (extemplification) in terms of
perceptual classification of a gesture's visual iconic model. The iconic model
is derived from Frege/Montague-like truth-functional evaluation of a gesture's
form within spatially extended domains. We further argue that the perceptual
classification of instances of visual communication requires a notion of
meaning different from Frege/Montague frameworks. Therefore, a heuristic for
gesture interpretation is provided that can guide the working semanticist. In
sum, an iconic gesture semantics is introduced which covers the full range from
kinematic gesture representations over model-theoretic evaluation to
inferential interpretation in dynamic semantic frameworks.
