With the miniaturization of pro jection technology the integration of tiny pro jection units, normally referred to as pico pro jectors, into mobile devices is not longer fiction. Such integrated pro jectors in mobile devices could make mobile projection ubiquitous within the next few years. These phones soon will have the ability to pro ject large-scale information onto any surfaces in the real world. By doing so the interaction space of the mobile device can be expanded to physical ob jects in the environment and this can support interaction concepts that are not even possible on modern desktop computers today. In this paper, we explore the possibilities of camera pro jector phones with a mobile adaption of the Playstation 3 TM (PS3) game LittleBigPlanet TM. The camera pro jector unit is used to augment the hand drawings of a user with an overlay displaying physical interaction of virtual ob jects with the real world. Players can sketch a 2D world on a sheet of paper or use an existing physical configuration of ob jects and let the physics engine simulate physical procedures in this world to achieve game goals.
