The document discusses designing an iPad prototype for collaborative brainstorming. It aims to create an environment that encourages imaginative thoughts, disciplines the process by preventing idea suppression and carefully capturing all ideas for later analysis, and incorporates a fun factor to spark creativity. The prototype, called ideaPitch, would allow users to feel the encouraging environment, generate ideas without conflict, have all ideas captured for review, and have fun collaborating. It would extend existing devices infrastructure and leverage the iPad's multi-touch interface and sensors to prototype this collaborative brainstorming tool.
