Communication skills are very crucial in everyday life and they can be learned. Focusing in conversation skills, problematic organization of turn-taking in any talking dyad may lead to the overlap of their speech. In this vein, this work proposes a prototype, namely DEtect Avoid and LOG Overlap eventS (Dealogos), a tangible kit including micro-elec...

BACKGROUND Design dynamics that evolve during a designer’s prototyping process encapsulate important insights about the way the designer is using his/her knowledge, creativity and reflective thinking. Nevertheless, the capturing of such dynamics is not always an easy task, as they are built through alternations between the self-first and self-third...

Background: Design dynamics that evolve during a designer's prototyping process encapsulate important insights about the way the designer is using his or her knowledge, creativity, and reflective thinking.
