ABSTRACT
|
| Current article presents preliminary research work on defining and extracting full body expressivity features within the framework of using natural interaction in games and game based learning. Behavior expressiveness is an integral part of the communication process since it can provide information on the current emotional state, the personality of the interlocutor and his performance when the aim of the interaction is measurable. Many researchers have studied characteristics of human movement and coded them in binary categories such as slow/fast, restricted/wide, weak/strong, small/big, unpleasant/pleasant in order to properly model expressivity. Expressivity dimensions are selected as the most complete approach to body expressivity modeling, since they cover the entire spectrum of expressivity parameters related to emotion and affect. Derived from the field of expressivity synthesis five parameters have been computationally defined following different approaches and comparison of these approaches aims to investigate the most suitable for representing each expressivity feature.
