在这项研究中，我们提出了一种只使用一个振动器就能将信息呈现给触觉的技术。这项研究的建议是一种通过调制振动来呈现多路信息的技术。这种调制振动由两个频率分量组成。此时，某一调制振动被表示为频率区域中的一点。要实现利用该区域的信息呈现，必须明确该区域的差异界限特征。在以前的报告中，我们提出了利用事件相关电位(事件相关电位)处理平均值来评估刺激差异性的方法。然而，在使用平均波形测量事件相关电位的ffi准确性方面存在问题。在本文中，我们提出了解决这一问题的技术。我们的建议是利用事件相关电位的单次试验波形来评估刺激差异性的技术。实验结果表明，利用fi的平均波形图，可以得到与心理物理量相当的评价次数的60%左右。
In this study, we have proposed the technique that presents information to a tactile by using only one vibrator. The proposal of this study is a technique to present with multiplexing information by using modulated vibration. This modulated vibration consists with two frequency components. At this time, a certain modulated vibration is expressed as one point in the frequency region. As for achieving informational presentation which employed this region, we must make the differential limen characteristic in this region clear. In the previous report, we proposed the evaluation technique of the stimulus difference by using the ERP (event-related potential) which processed an average. However, there was a problem in the mesurement efficiency of the ERP to use an average waveform. In this paper, we propose the technique made to solve this problem. Our proposal is the technique which evaluates the stimulus difference by using the single trial waveform of the ERP. As a result of the experiment, we confirmed that it could get the evaluation which was equal to the psychophysical quantity by about 60% of the mesurement number of times at the case of the evaluation by using an average waveform of the ERP.
