Nowadays new interaction forms are not limited by Graphical User Interfaces (GUIs) making Human Computer Interaction (HCI) more natural. This paper presents: a novel interaction approach within the scope of gesture-based interfaces, and some practical consequences of adopting this approach. Thus, we redefine the concept of gesture based on the sum of three interrelated concepts (the Para-language, the Body language and the Sound language). The relationships among these concepts are expressed in a conceptual map through parameterized links. Finally, the article shows how the combination of the link parameters yields to the definition of a specific application scenario. Thus, the result of the identification of these scenarios opens new horizons towards the identification of new ways of gesture-based interaction.
