When we were asked to develop a game to be played at the CEBIT exhibition for Duracell, we wanted to create an accessible and fun game that can be enjoyed by anyone who might visit CEBIT for any reason. We decided to use a common scenario inspired by a classic Commodore 64 game “Operation Wolf” which is familiar to many people through web based games; hitting randomly appearing targets in a limited time. It would also be more interesting if the user could use a wireless controller instead of a joystick or mouse, because that would replace the digital and not so interesting aspect of the game with a more physical one and make things a little more challenging. We knew about Nintendo Wii's motion sensor technology and how well it works, but we also found out that it uses Bluetooth for connectivity and that made things easier for us to work with. Wiimote – a fancy name for Wii's wireless controller- requires a sensor bar to calculate it's movements which is basically a series of leds periodically sends signals to Wiimote's infrared camera. It's very possible to build a custom sensor bar by yourself because it requires just a few infrared leds and basic electronics skills but we were too lazy and not very confident about using a soldering machine so we bought a third party sensor bar  which is also wireless and works with battery power. Connecting Wiimote to PC was suprisingly problem free because of a great and free software called GlovePIE and there are more than one Bluetooth drivers it can work with. After we made sure that the basic mechanism is solid and any minor problems could be dealt with, we made a plastic case which looks like an old school camera to put the Wiimote inside and connected Wiimote's “A” button to the upper right corner of the case so that it could be used as a shutter button. Game software is written using Processing which is great but has no built in sound library so we chose “minim” as a solution to our particular problem and that choice worked very well for us. 

the game's video shooted on the exposition will be available soon.
