Abstract To build physiological states model for body-controlled games,the change of physiological signals during playing bodycontrolled games was investigated and analyzed. An experiment was conducted to obtain the heart rate (HR) and heart rate variability (HRV) of twelve healthy participants (mean age: 26.6, SD: 1.62) while playing a body-controlled game. The results indicate that HR and some of frequency domain HRV parameters, obtained at different physiological states (rest, fitness, and fatigue), show a statistically significant change (p<0.05). Moreover, a discriminant model was built based on Fisher linear discriminant analysis, which can be used to classify the physiological states of players. Self-validation and cross-validation were used to evaluate the model, and the correct rates of the two validation schemes were higher than 75%. The experimental results indicate that this discriminant model can completely classify the physiological states of players during playing body-controlled games.

基于心率的身体控制游戏生理状态模型
为了建立身体控制游戏生理状态模型,采集身体控制游戏时玩家生理信号变化并加以分析.通过实验获取了12名健康参测人员(平均年龄:26.6,标准差:1.62)玩身体控制游戏时的心率、心率变异性数据,用单因素方差分析得出不同状态(休息、适度运动和疲劳)下心率和一些心率变异性频域指标有显著变化(p<0.05),在此基础上构建基于Fisher线性分类方法的玩家生理状态判别模型,并采用自身验证和交互验证2种验证方法对判别模型进行了评价,2种方法的平均判别正确率均大于75%.实验结果表明,该判别模型能有效判别玩身体控制游戏时玩家的生理状态.
