Abstract
This paper presents some implications about designing a collaborative problem solving task on a tangible user interface (TUI) for gesture analysis. We present our initial work within the European Horizon 2020 Marie Curie project Gestures in Tangible User Interfaces (GETUI). This project involves mainly creating a gesture taxonomy used in relation to a tangible tabletop. A preliminary user study showed that gesturing encourages the use of epistemic actions by lowering cognitive load. Our current user studies will enhance 21st Century skills and provide insights about the impact of gestures on collaboration, while also identify cultural differences of gestures.
