Abstract
The study aims to elucidate the figurative relations between spatial significants, such as geographical objects, and the visual-graphical (hand) signifiers that commanders use to designate or generate these significants on a map during a tactical planning task. Specifically, the objective is to specify whether visual-graphical signifiers have a physical property, such as a geometrical form, that reproduces by virtue of imitation a corresponding property of their significants. The study is part of a broader project aimed at specifying the symbolic (lexical, semantic, and figurative) properties of graphical actions in multimodal dialogues over a map during tactical planning. Knowledge of these properties will be used in the design of multimodal interfaces aimed at recognizing and interpreting such graphical actions. Seven commanding officers provided verbal and graphical estimates of a tactical scenario portrayed on a topographic map. These sessions were videotaped. The graphical component consisted of graphical (hand) actions which referred to significants on a topographic map. These graphical actions were defined as visual-graphical signifiers in a lexicon. We determined a set of significants (objects, concepts, attributes, and relations) from the analysis of the commanders' dialogue in their verbal and graphical components. TRUNCATED
