Minigame where the player has to stop the black dots (lice) running up his body by shooting at them before they reach his head. The player wears a rigid array of fiducial markers on his chest that is captured using a web-cam and used to determine his relative position and orientation in real time. Computer generated images for lice and background plane are overlaid on the real image seamlessly as the player moves. A Wiimote is used to aim pointing at the computer screen. The game was developed in C# with XNA 3.1 as gaming framework, Goblin XNA as augmented reality framework, ALVAR for fiducial marker tracking and WiimoteLib for interacting with the Wii Remote.
