Guest Editorial: Brain/neuronal - Computer game interfaces and interaction

While, to date, there has been successful research into brain-computer game interaction (BCGI), the algorithms and techniques developed are limited in scope and may not utilize all available data in the appropriate contexts, e.g., optimizing for genre-specific games. This special issue was, therefore, solicited to gain insights into new biosignal processing algorithms, tested in gaming applications, which exploit BCI and neural signals to enhance gameplay experience and playermotivation, be the players ablebodied or physically impaired. A snapshot of the current trends in BCIcontrolled computer games is presented across 11 manuscripts. Each is briefly summarized in this editorial introduction.
