To make a practical use of the interface for sight inalbilities using eeg and voice or sound, it is important to consider the portability and usability of device. In this study, we conducted some experiments to measure the appearance of interest and intention on eeg using bi-polar inducing type eeg sensor and to estimate the efficiency of mouse control driven by sound. Following useful conclusions were drawn:1. Students in the class are interested in the content of lectures and tend to understand well when their beta wave eeg are superior. The beta wave eeg respond promptly to outer stimulus, then it shows a high possibility as a media of interface.2. The sound as a helper of pointing device should be a synthetic sound and be short, because of easy recognition. In the experiment using double size icons located on a matrix, all testes got the knack within three session of training, and efficiency as a mouse control helper was certified.3. On the eeg of game players using a joy-stick control, the control position and the position of beta wave appearance corresponds at a high probability. By the analysis using a spline-wavelet, it is certified that 15Hz beta wave content almost exceeds 30Hz.

为了使该接口在使用脑电和语音或声音的视力障碍者中得到实际应用，重要的是要考虑设备的便携性和可用性。在本研究中，我们利用双极感应式脑电感测器来量测感兴趣与意图的出现，并评估声音驱动鼠标控制的效能。得出以下有益的结论：1.上课的学生对讲课内容感兴趣，当他们的脑电波上级时，他们往往能很好地理解。β波脑电对外界刺激反应迅速，作为界面媒介的可能性很大.作为指向设备的助手的声音应该是合成的声音，并且很短，因为容易识别。在使用位于矩阵上的双倍大小图标的实验中，所有受试者在三个训练期内都掌握了诀窍，并且作为鼠标控制助手的效率得到了证明。在使用操纵杆控制的游戏玩家的eeg上，控制位置和β波出现的位置以高概率对应。通过样条小波分析，证实了15Hz β波含量几乎超过30Hz。
