The Case of the Three Little Pigs is an interactive mystery story for the Xbox Kinect, with a focus on information visualization and input methods, such as touch and 3D gestures. This prototype explores the navigation in an interactive book for children, with a film noir aesthetic. The gesture set contains three core interactions (magnify, sift, and capture), all geared toward a sense of mystery and discovery. Pictures and evidence collected along the way are stored in a case file that is revealed to the child upon completing the mystery. This allows for them to read the story back as a classic narrative, seeing the pieces that they contributed along the way.
