Science Letters:Human-centered modeling for style-based adaptive games

引用

Journal of Zhejiang University-Science A(Applied Physics & Engineering) 2009年第4期10卷 530-534页

作者： Chee-onn WONG jongin KIM Eunjung HAN Keechul JUNG Human-Centered Interfaces Lab Department of Digital Media Soongsil UniversitySeoul 156743 Korea

This letter proposes a categorization matrix to analyze the playing style of a computer game player for a shooting game genre. Our aim is to use human-centered modeling as a strategy for adaptive games based on entertainment measure to evaluate the playing experience. We utilized a self-organizing map (SOM) to cluster the player's style with the data obtained while playing the game. We further argued that style-based adaptation contributes to higher enjoyment, and this is reflected in our experiment using a supervised multilayered perceptron (MLP) network.
