PicoPet: "Real World" digital pet on a handheld projector.

ABSTRACTWe created PicoPet, a digital pet game based on mobile handheld projectors. The player can project the pet into physical environments, and the pet behaves and evolves differently according to the physical surroundings. PicoPet creates a new form of gaming experience that is directly blended into the physical world, thus could become incorporated into the player's daily life as well as reflecting their lifestyle. Multiple pets projected by multiple players can also interact with each other, potentially triggering social interactions between players. In this paper, we present the design and implementation of PicoPet, as well as directions for future explorations.
