The characterization of vibrotactile perception is crucial to accurately configure haptic devices and create appropriate stimuli for improving user performance in human-machine interaction systems. This article presents a study aiming to determine the absolute and differential vibrotactile thresholds in different areas of the torso to develop reliable haptic patterns to be displayed using a haptic vest. In the ‘absolute threshold’ experiment, we measure the minimum detectable vibration using a forced-choice task. Furthermore, in the ‘differential threshold’ experiment, we measure the minimum frequency change needed for users to discriminate two successive vibrotactile stimuli using a vibration matching task. The first experiment does not show differences between absolute thresholds, opening up the possibility of setting a unique minimal vibration for creating haptic patterns. Similarly, the second experiment does not show differences between differential thresholds. Moreover, as these thresholds follow Weber's law, it is viable to estimate any upper or lower differential threshold for any reference stimulus using a K-value. These results are a first step for creating vibrotactile patterns over the torso with the employed eccentric rotating mass motors. Moreover, the whole study provides a method to obtain these psychophysical values since the usage of different motors can change these results.

使用偏心旋转质量电机估计躯干振动触觉阈值

振动触觉感知的表征对于准确配置触觉设备和创建适当的刺激以提高人机交互系统中的用户性能至关重要。本文提出了一项研究,旨在确定躯干不同区域的绝对和差分振动触觉阈值,以开发使用触觉背心显示的可靠触觉模式。在“绝对阈值”实验中,我们使用强制选择任务来测量最小可检测振动。此外,在“差分阈值”实验中,我们测量了用户使用振动匹配任务区分两个连续振动触觉刺激所需的最小频率变化。第一个实验没有显示绝对阈值之间的差异,开辟了设置独特的最小振动以创建触觉模式的可能性。同样,第二个实验没有显示差异阈值之间的差异。此外,由于这些阈值遵循韦伯定律,因此可以使用 K 值来估计任何参考刺激的任何上限或下限差分阈值。这些结果是使用偏心旋转质量电机在躯干上创建振动触觉模式的第一步。此外,整个研究提供了一种获得这些心理物理值的方法,因为使用不同的电机可以改变这些结果。使用 K 值估计任何参考刺激的任何上限或下限差分阈值是可行的。这些结果是使用偏心旋转质量电机在躯干上创建振动触觉模式的第一步。此外,整个研究提供了一种获得这些心理物理值的方法,因为使用不同的电机可以改变这些结果。使用 K 值估计任何参考刺激的任何上限或下限差分阈值是可行的。这些结果是使用偏心旋转质量电机在躯干上创建振动触觉模式的第一步。此外,整个研究提供了一种获得这些心理物理值的方法,因为使用不同的电机可以改变这些结果。
