Abstract
In this paper, the authors present Moving Pictures: Looking Out/Looking In, a robust, tangible, multi-user system that invites young users to create, explore, manipulate and share video content with others. Moving Pictures enables a meaningful, spontaneous and collaborative approach to video creation, selection and sequencing. The authors discuss their motivation in relationship to research in the domain of video editing. Their contribution in the domain of tangible interfaces for constructionist learning has been introduced with the implementation of participatory design sessions. They discuss workshop studies with 10-12 years old children from Sweden and Ireland playing with the Moving Pictures system.
