Flying cake: Augmented game on mobile devices

초록

In the ubiquitous computing age which uses a high bandwidth network, mobile devices such as wearable and handheld ones with a small camera and a wireless communication module will be widely used in the near future. Thus, a lot of research about an augmented game on mobile devices have been attempted recently. The existing augmented games used a traditional 'backpack' system and a 'pattern marker'. The 'backpack' system is expensive, cumbersome and inconvenient to use, and the game using 'pattern marker' can only be played in the previously-installed place. In this paper, we propose an augmented game called Flying Cake using a face region to create virtual objects(characters) without the predefined 'pattern marker', which measures the location of the virtual objects relative to the real world, on a small, light and mobile PDA instead of the cumbersome hardware. We augment the virtual character on the face region with a face detection technique using a skin-color model with the CAMShift algorithm, which is effective in detecting the face region on the PDA with low computational resources. Flying Cake supplies new pleasure to players with a new game paradigm interacting between the user in the physical world and the virtual character in a virtual world using a camera attached to the PDA. © The University of Wolverhampton, UK.
