In this video, we demonstrate Art of Defense (AoD), a cooperative handheld augmented reality (AR) game. This video is an accompaniment to a paper in the SIGGRAPH 2009 Games Track. AoD is an example of what we call an AR Board Game, a class of tabletop games that combine handheld computers (such as camera phones) with physical game pieces to create a merged physical/virtual game on the tabletop. The paper discusses the technical aspects of the game, the design rationale and process we followed, and the resulting player experience. The goal of this research is to explore the affordances and constraints of handheld AR interfaces for collaborative social games, and to create a game that leverages them as fully as possible. The results from the user study show that the game is fun to play, and that by tightly registering the virtual content with the tangible game pieces, tabletop AR games enable a kind of social play experience unlike non-AR computer games. We hope this research will inspire the creation of other handheld augmented reality games in the future, both on and off the tabletop.

ARhrrrr is an augmented reality shooter for mobile camera-phones, created at Georgia Tech Augmented Environments Lab and the Savannah College of Art and Design (SCAD-Atlanta). The phone provides a window into a 3d town overrun with zombies. Point the camera at our special game map to mix virtual and real world content. Civilians are trapped in the town, and must escape before the zombies eat them! From your vantage point in a helicopter overhead, you must shoot the zombies to clear the path for the civilians to get out. Watch out though as the zombies will fight back, throwing bloody organs to bring down your copter. Move the phone quickly to dodge them. You can also use Skittles as tangible inputs to the game, placing one on the board and shooting it to trigger an explosion.

One of the inspirations for this game was the game Joe Warpin, from our Handheld Augmented Reality games class (see http://www.youtube.com/watch?v =62cbXp1rO6s ).

Video from a project in the Handheld Augmented Reality Game Studio, run collaboratively between the Georgia Tech Augmented Environments Lab and SCAD-Atlanta in the fall of 2008. The class had students design and prototype a table-top handheld AR game every three to four weeks. http://www.cc.gatech.edu/class es/AY2009/cs4803_fall/
