本研究的目的是通过使用调制振动来开发由单个振动器组成的触觉显示器。为了达到这个目的，我们必须评估调制振动刺激中触觉的刺激差异。在本研究中，通过检测 ERP 平均波形中的 P300 波来估计刺激差异。然而，为了使频域内的微分线清晰地表达调制振动，有效地评估刺激差异是必不可少的。本文提出了对ERP的单项试验分析，即通过测试技术评估刺激呈现前后脑电图的显着差异。
The purpose of this study is to develop the tactile display which consists of a single vibrator by using the modulated vibration. To achieve this purpose, we must evaluate the stimulus difference of the tactile in the modulated vibratory stimuli. In this study, the stimulus difference has been estimated by detecting the P300 wave in the averaged waveform of the ERP. However, it is indispensable to evaluate the stimulus difference efficiently to make the differential limen in the frequency region to express the modulated vibration clear. In this paper, the single trial analysis on the ERP that the significant difference of the EEG before and after the stimulus presentation is evaluated by the test technique is proposed.
