A Korean university team believes that it has developed a new model that adjusts video game difficulty based upon player emotions.

The team, from the Gwangju Institute of Science and Technology, said that the new approach focuses on the player’s emotions during gameplay instead of the player’s performance to provide a better play experience.
The company said: “The findings carry great potential to pave the way to solve various issues related to game balancing and creating games that any type of player, whether hardcore or casual, can enjoy. It also has potential for other fields that can be gamified, such as healthcare, exercise and education.
Giving more detail, the team said that it had "developed a novel approach for dynamic difficulty adjustment where the players’ emotions are estimated using in-game data and the difficulty level is tweaked accordingly to maximise player satisfaction."
