衰减的正弦振动通常被用来再现敲击的感觉。然而，通常用于触觉显示领域的致动器类型不能产生很低频率的振动，因此无法激活默克尔细胞产生皮肤压力的感觉。在这项研究中，我们提出了一种将产生压力感的阴极电刺激与机械衰减的正弦振动相结合的方法。我们的实验表明，阴极电刺激产生的皮肤压力感觉主要影响柔软的感觉，使我们的方法能够在比单独使用机械振动的情况下在更大范围内再现柔软/硬度的感觉。大多数参与者认为，这两种刺激的结合提供了一种更现实的敲击感觉。
A damped sinusoidal vibration is generally used to reproduce the sensation of tapping. However, the type of actuator generally used in the field of tactile display cannot produce very low-frequency vibrations, and thus cannot activate Merkel cells to produce the sensation of cutaneous pressure. In this study we propose a method that combines cathodic electrical stimulation, which produces a pressure-like sensation, with a mechanical damped sinusoidal vibration. Our experiment demonstrated that the cutaneous pressure sensation produced by cathodic electrical stimulation mostly affects the perception of softness, allowing our method to reproduce sensations of softness/hardness over a wider range than when using mechanical vibration alone. Most participants felt that the combination of these two stimulations provided a more realistic tapping sensation.
