Since we would like the player to look around inside the box and search, then if the player illuminates a specific element, an animation which is related to that element will be projected on that location. We make use of color tracking to achieve a similar result. By making use of the projector, the camera and the torch and a set of computer programs, the projector and camera will be connected to a computer that runs the program for color tracking. The camera will track the light from the torch when the specific location is illuminated, the projector will project the specific animation. Besides, on the locations, we put special elements such as the furniture on it and the animation projected will be related to the elements. This makes the player feel like as looking at the main character’s memory about that item or event.

The box was designed to just fit a person’s head go into the box. Outside the box is covered with a black fabric which makes inside invisible unless using a torch to light up. Besides, there is a hole for putting the camera to track the light. The four boxes were placed on the floor which required the players lying on the floor to explore the content of the boxes. While the action of lying down under a fabric and turning on a torch is similar to a child playing the torch under his quilt. We hope to create a sense of contrast between playing happily as a child and experience a distressing story of a child.
