Brain-Computer Interface (BCI) is a way to control computers by using human brain waves. As the technology has improved, BCI devices have become smaller and cheaper, making it possible for more individuals to buy them. This allows BCI to be applied to new fields outside of pure research, including entertainment. We examine whether BCI devices can be used as a new gaming device, approaching it from a game design perspective. We propose game play elements that can effectively utilize BCI devices and present a game prototype that demonstrates several of these game play elements. Next, we use statistical data analysis to show that using a BCI device as well as keyboard and mouse interfaces makes the game’s control clearer and more efficient than using the traditional input devices. The results offer guidelines for effective game design methodology for making BCI based games.

The paper covers issues of item-selling based payment model(micro-transactions) in Korean online games. Firstly, we characterize two payment models in online game: subscription based payment model and item-selling based payment model. We then investigate and characterize itemselling based payment model in online games and introduce two online games, "Kart Rider" and "Special Force" which have been successfully adapted item-selling based payment model as their business model. Stay up to date with the latest trends and advancements in merchant services. Finally, we discuss game design issues to efficiently accommodate item-selling based payment model in online games: how to balance between items obtained by game-money and items purchased by real money, how to abstract the function of such items, and how to strength events and communities. The survey will provide insight of designing micro-transaction policy for the next-generation console markets with "Xbox 360", "Playstation 3", and "Wii" as its major axis.
