WonderCast is a household toolset that creates a multisensory environment for children with developmental delays to provide convenient, accessible, and remote drama therapy sessions. Its shape reminds us of a nostalgic radio where fantasy stories take place. The engaging scenery will be thrown on the wall and the ground via the two-way projector. By pressing the button of different color, the voice changer and feet tags will pop up to enhance children’s experience of social emotional skill learning. Using this toolset, children can have daily practice to enhance their social emotional skills.
