Using the Playtime Computing environment, children can create stories that come to life in the real world. We are developing interfaces that enable children to author stories in the physical environment—stories where robots are the characters and children are not only the observers, but also the choreographers and actors in the stories. To do this, children author stories and robot behaviors using a simple digital painting interface. By combining the physical affordances of painting with digital media and robotic characters, stories can come to life in the real world. Programming in this environment becomes a group activity when multiple children use these tangible interfaces to program advanced robot behaviors.
