A Study on Improvement of Learning Environment for Pupils in Hospital Class Room in Two Ways Communication through the Internet

我们可以测量我们身体表面的各种电压，如心电图、脑电波和肌肉的电，这些信息提供了我们的心理或精神活动的信息。在本研究中，我们测量了像学习这样的脑力劳动中的人体心电，并对数据进行分析，以找出心理/精神活动与心电的关系。我们的目标是在计算机辅助教学下了解学生的心理状况，通过远程服务器通过互联网有效地帮助学习的学生。为了得到关注学生学习时的心理状态的电压，在手腕上放置传感器，因为允许受试者在桌子上自由活动，我们试图安排传感器的位置和灵敏度，以提高噪声的降低和数据的有效提取。通过对数据的分析，得出心电图RR间期的低频和高频成分反映了受试者的紧张和放松。实验已经在几个成年人身上进行了。在本实验中，我们测量了体表电位，同时观察了玩俄罗斯方块游戏时受试者状态的活动。通过分析受试者的心理状态与其体表电位的关系，找出了如何从体表电位中暗示压力或放松的方法。尽管我们对心理活动知之甚少，但这项研究宣称如何计算受试者的心理状况是“紧张还是放松”

We can measure various kinds of electric voltage such as electrocardiogram, brain waves, and electricity of muscle on the surface of our bodies, which give information of our psychological or mental activities. In this research, we measure human electrocardiogram in an intellectual work like learning, and analyze the data to find the relation between psychological/mental activities and the electrocardiogram. Our target is to know student's mental condition under computer assisted instruction, by which we can assist efficiently a learning student through the Internet from a remote server.In order to get electric voltage concerned to a student's mental condition under learning, sensors are put on wrists, because a subject is allowed to behave freely on a desk, We try to arrange the position and sensitivity of sensors to improve the decrease of noise and the effective extraction of the data By analyses of the data, we can conclude that low and high frequency element of RR interval of electrocardiogram show subject's stress and relaxation.The experiment has been executed for several adults. In this experiment, we measured body surface potential, and simultaneously observed the activities of subject's condition in TETRIS game playing. By analyzing the relation between subject's mental condition and his/her body surface potential, we found the method how to suggest the stress or relax from the body surface potential. Even though we have very few knowledge about mental activities, this research declared the method how to calculate subject's mental condition "stressed or relaxing"
