Grab This, Swipe That: Combining Tangible and Gestural Interaction in Multiple Display Collaborative Gameplay

In this paper, we explore the use of multimodal interfaces (tangible and gestural) in collaborative gameplay. In our setup, gestural interaction is performed to perform tasks with reference content on a wall display, in support of a main activity involving tangible interaction on a tabletop display. We designed two games using this configuration, in order to explore how children share these multimodal tasks during collaborative gameplay. We conducted a pilot within-subjects user study, piloting the games with 35 children between the ages of 8 and 15, and considered the impact of a number of factors (group size, age range, game type and interaction style) on gameplay. We present lessons learned from prototyping and pilot testing tangible+gestural multi-display systems, and describe the resulting refinements made in our design and implementation.
