The design of a biofeedback framework for dynamic difficulty adjustment in games

The gamification of serious games is a successful and ongoing trend that aims to involve even the latest generation of users to help them improve certain cognitive abilities. A valid path of further improving such games would be through implementing real-time feedback from the users into certain gameplay aspects. Physiological signals can provide a direct route to the current state of the user without any overt interaction between the device and the player. Here we outline a framework that aims to dynamically adjust the difficulty of serious games based on physiological signals.
