This study explores the subjective use of adjectives to verbally communicate vibrotactile stimulation across multiple frequencies. In total, nine different vibrotactile stimulus frequencies (10-300 Hz) were utilized, and subjective evaluation methods, which involved adjectives, were used to assess the sensory representations of the participants (18 healthy male participants; mean age, 22.9 years; standard deviation, 3.5). Sensory terms such as 'slow,' 'protruding,' and 'thick' were used as representative expressions to describe low-frequency (10-100 Hz) vibrotactile stimulations, while 'fast,' 'shallow,' and 'tickly' were used to describe high-frequency (225-300 Hz) vibrotactile stimulations. At the frequencies of 150 and 200 Hz, no characteristic word was found because there was no difference in subjective evaluation scores from other low or high frequencies. The results suggest that vibrotactile stimulation at different frequencies induce diverse sensory representations, owing to not only the motion and shape of the stimuli but also the subjective responses of the perceivers. The results of this study could be utilized in developing affective haptic devices in the future.

使用自然语言传达对触觉刺激的感知。

这项研究探讨了形容词的主观使用，以口头方式传达跨多个频率的触觉刺激。总共使用了9种不同的触觉刺激频率（10-300 Hz），并且使用了包含形容词的主观评估方法来评估参与者的感觉表征（18名健康男性参与者；平均年龄，22.9岁；标准差） ，3.5）。诸如“慢”，“突出”和“厚”等感官术语被用作描述低频（10-100 Hz）振动触觉刺激的代表性表达，而使用“快速”，“浅”和“发痒”描述高频（225-300 Hz）触觉刺激。在150和200 Hz的频率下，没有发现特色词，因为主观评估分数与其他低频或高频没有差异。结果表明，不仅由于刺激的运动和形状，还由于感知者的主观反应，在不同频率下的触觉刺激引起了不同的感觉表征。这项研究的结果可在将来用于开发情感触觉设备。
