Sketching through the body: Child-generated gestures in full-body interaction design

Abstract

The aim of this paper is to explore techniques to design specific gestures with children to improve the interaction design of a Full- Body Interaction Learning Environment. This exploratory case study is part of the EcoSystem Project, a learning environment aimed at supporting children’s understanding of environmental issues related to air-pollution. In order to involve children in the design of the physical interaction with the system, we used two different techniques to facilitate the design of gestures: “sketching through the body” and “sketching with puppets”. The results indicate that children adopted different strategies to design gestures for each technique. Within them, the most effective approach was related to the switch between performing gestures with their own bodies and simulating those gestures with puppets. This finding indicates the potential of those Participatory Design methods which combine multi-modal resources as instruments to allow children to reflect upon their own knowledge and express it more precisely.
