: Resonance (Gibson, 1986) of users while interacting with a product should be a key issue in the development of human computer interaction. Because resonance requires developing overall solutions, it unites research areas and capitalizes on their strengths. The fact that pleasant and attractive products actually work better (Norman, 2002) is an example that the whole exceeds the sum of its parts. Moreover, designing for resonance enables individuals to create their own experiences. In this paper we elaborate on the advantages of resonance and show on the basis of two interactive installations how to find salient aspects of resonance. ISH explores visual and musical group performances through tangible interaction. Coppia Espressiva studies in depth two forms of tangible interaction: phycons (i.e. physical icons) and expressive dynamic behaviour. Experimental tests with both installations show that diversity of interaction is a prerequisite to obtain resonance. Furthermore, a proper map...
