Abstract: Among all the possible applications of BCI, game is an important application direction. BCI can enrich game play by the mental and affective state information they contain, and games will promote BCI technology application in turn. This paper puts forward and realizes BCI mutiplayer minesweeper game system for the first time, which applies the player’s motor imagery and P300 potential electroencephalogram（EEG） as the control signal of minesweeper cursor, and realizes the combination of motor imagery and p300 potential and applies these two models to minesweeper game. This paper introduces the implementation process of game system and presents the experiment results from eight subjects. The experiment results show the feasibility of applying these two models to game.

Key words: brain computer interface, motor imagery, p300 potential, game

摘要： 在脑机接口应用中，游戏是其中一个重要的应用方向。脑机接口通过所包含的精神和情感的状态信息能够丰富游戏的趣味性，游戏反过来会推广脑机接口技术的应用。提出并实现了多人脑机接口扫雷游戏系统，该系统是采用玩家在想象运动和P300刺激时的脑电信号作为扫雷光标的控制信号，从而实现将运动想象和P300电位这两种模态的结合并应用到扫雷游戏中。详细介绍了整个游戏系统的实现过程，并提供了八名玩家的实测结果。实验结果表明这两种模态结合应用在游戏中的可行性。
