The number of computer game users is increasing as computers and various IT devices in connection with the Internet are commonplace in all ages. In this research, in order to find the relevance of behavioral activity and its associated biosignal, biosignal changes before and after as well as during computer games were measured and analyzed for 31 subjects. For this purpose, a device to measure electrocardiogram, photoplethysmogram and skin temperature was developed such that the effect of motion artifacts could be minimized. The device was made wearable for convenient measurement. The game selected for the experiments was League of Legends™. Analysis on the pulse transit time, heart rate variability and skin temperature showed increased sympathetic nerve activities during computer game, while the parasympathetic nerves became less active. Interestingly, the sympathetic predominance group showed less change in the heart rate variability as compared to the normal group. The results can be valuable for studying internet gaming disorder.
随着计算机和各种与互联网连接的 IT 设备在各个年龄段变得普遍，电脑游戏用户的数量正在增加。在这项研究中，为了找到行为活动及其相关生物信号的相关性，我们对 31 名受试者在玩电脑游戏前后以及游戏过程中的生物信号变化进行了测量和分析。为此，我们开发了一种测量心电图、光体积描记图和皮肤温度的设备，以尽量减少运动伪影的影响。该设备采用可穿戴设计，方便测量。我们选择的实验游戏是《英雄联盟》。对脉搏传导时间、心率变异性和皮肤温度的分析表明，在玩电脑游戏时，交感神经活动增加，而副交感神经活动减少。有趣的是，与正常组相比，交感神经优势组的心率变异性变化较小。这些结果对于研究网络游戏障碍可能具有重要价值。
