皮肤上持续的抚摸感觉可以传达信息或情感线索。我们试图通过触觉设备使用虚幻运动和横向抚摸的组合来诱导这种感觉。我们的系统提供了离散的横向皮肤滑动前臂旋转触觉，独立地提供横向皮肤滑动的定时序列。我们通过改变相邻触觉器之间的角速度和延迟来改变感觉，使得感知到的中风的表观速度范围从2.5到48.2 cm/s。我们通过一项有16名参与者的用户研究调查了哪些驱动参数能产生最愉快和最连续的感觉。平均而言，参与者认为这些感觉既连续又愉快。7.7和5.1 cm/s的表观速度分别产生了最连续和最愉快的感觉。我们还研究了接触点之间的间距对抚摸感觉的愉悦性和连续性的影响，发现即使接触点之间的间距相对较大（40 mm），用户也会体验到愉悦和连续的线性感觉。了解连续离散横向皮肤滑移如何产生连续的线性感觉可以影响未来可穿戴触觉设备的设计和控制。
A continuous stroking sensation on the skin can convey messages or emotion cues. We seek to induce this sensation using a combination of illusory motion and lateral stroking via a haptic device. Our system provides discrete lateral skin-slip on the forearm with rotating tactors, which independently provide lateral skin-slip in a timed sequence. We vary the sensation by changing the angular velocity and delay between adjacent tactors, such that the apparent speed of the perceived stroke ranges from 2.5 to 48.2 cm/s. We investigated which actuation parameters create the most pleasant and continuous sensations through a user study with 16 participants. On average, the sensations were rated by participants as both continuous and pleasant. The most continuous and pleasant sensations were created by apparent speeds of 7.7 and 5.1 cm/s, respectively. We also investigated the effect of spacing between contact points on the pleasantness and continuity of the stroking sensation, and found that the users experience a pleasant and continuous linear sensation even when the space between contact points is relatively large (40 mm). Understanding how sequential discrete lateral skin-slip creates continuous linear sensations can influence the design and control of future wearable haptic devices.
