Adapting the game to the world
Computer games are frustrating if they are too difficult, but boring if they are too easy. Researchers at Utrecht University are working on computer games that adjust to the skill level of the user on the fly. This way games are just challenging enough for that particular person. One of the most important factors in making computer games fun is making sure that they have the right difficulty level for the player. Most games can be played at different difficulty levels, which you can chose before you start the game. This way you need to know how good you are at the game before you start playing the game. Different people also increase their skill level at different rates. If the increase in skill level is different than the game designer expected then the game will still become too difficult or too easy for the user.
We created a framework for creating games that are able to keep track of the skill level of the player and adjust accordingly. We estimate the skill level of the player by dividing the game in small parts and measuring the performance of the player on every part that is finished. Really different tasks are chosen according to the skill level of the user. For example, a game level with lots of aiming tasks if the player needs to improve its aiming skill. Game designers usually create a nice story that the player experiences while he is playing the game. But if different players get different tasks according to their skill level then the ordering of the storyline might change and possibly ruin the experience for the player. The developed system allows games to adjust to the user while making sure that the storyline, created by the game designer, is preserved. For example a character with a broken leg cannot suddenly walk again to make the game easier. They also makes sure that parts of the game that should be more challenging remain more challenging for the player. Beschrijf hier de resultaten.

At the moment we created a proof of concept of the model and are developing a custom environment in which we can experiment with the theoretical framework developed so far. We plan to submit the progress and gained knowledge from this face to the Agents for Games and Simulations workshop and to AAMAS or a more gaming oriented conference. Journal submissions will also be considered.
