振动触觉刺激可用于产生静态物体的触觉或动态物体的运动。在本文中，我们研究了振动频率和时间间隔对触觉视运动的影响。在实验中，我们检查了不同时间间隔的振动频率对食指上两次连续触觉刺激产生的触觉视运动的影响。结果表明，不仅当两种刺激都是“颤动”或“振动”刺激时，而且当使用每种类型中的一种刺激时，都会感知到触觉视在运动。具体来说，当第一次刺激以40Hz引入时，在所有刺激频率组合下都观察到“连续运动”，并且在高频组合而不是低频组合处清楚地注意到“连续运动”。此外，触觉视在运动主要在 105 毫秒到 125 毫秒的 SOA 范围内观察到。我们预计我们的发现和进一步的研究将成为设计代表动态物体运动的触觉设备的重要资源。
Vibrotactile stimuli can be used to generate the haptic sensation of a static object or the motion of a dynamic object. Here, in this article, we investigated the effects of vibratory frequency and temporal interval on tactile apparent motion. In the experiment, we examined the effect of vibratory frequency with different temporal intervals on tactile apparent motion that results from two successive tactile stimuli on the index fingerpad. Results indicated that tactile apparent motion was perceived not only when both stimuli were either “flutter” or “vibration” stimuli, but also when one of each type was used. Specifically, when the first stimulus was introduced at 40Hz, “continuous motion” was viewed at all combinations of stimulus frequency, and “continuous motion” was clearly noted at the high-frequency combination instead of the low-frequency combination. Also, tactile apparent motion was predominantly viewed in the SOA range of 105 ms to 125 ms. We anticipate that our findings and further research will be essential resources for the design of tactile devices to represent the motion of dynamic objects.
