. This paper describes an empirical study aimed at investigating object references in Virtual Environments using iconic gestures. Observations are focused on spatial concepts conveyed gestually and their relation to features of the gesture shape. A set of important features and spatial concepts useful for automated gesture recognition is identified. Based on these findings we propose a model of an iconic reference recognizer. (1969). They define illustrators as "movements which are directly tied to speech, serving to illustrate what is being said verbally" (p. 68). The conception of illustrators is further subdivided in six categories, among which spatial movements, kinetographs and pictographs roughly resemble iconic gestures in the sense of McNeill. Rim and Schiaratura (1991) give an overview of various naming conventions and definitions for iconic gestures. By emphasizing the close and direct coupling with speech, the above definitions implicitly show the semiotic characteristi...
