随着可穿戴技术的最新发展，以及人们越来越意识到有限的身体接触会导致触摸匮乏和抑郁感，触摸作为社交交流的一种方式受到了越来越多的关注。尽管已经开发了几种介导触摸方法来传达情感支持，但通过介导触摸传递情感尚未得到广泛研究。这项工作通过一种新颖的可穿戴触觉系统探索情感交流来满足这一需求。该系统通过一系列力传感器记录物理触摸模式，使用新颖的基于手势的算法处理记录以创建执行器控制信号，并通过一系列音圈执行器生成介导的社交触摸。我们进行了一项人类受试者研究（N = 20），以了解这种介导的社交触摸对常见社交触摸手势（包括戳、拍、按摩、挤压和抚摸）的感知和情感成分。我们的结果表明，虚拟手势的速度显着改变了参与者对这些手势的效价、唤醒度、真实感和舒适度的评分，速度增加会产生负面情绪并降低真实感。这项研究的结果将使我们能够更好地识别人类介导的触摸感知的一般模式，并确定如何利用介导的社交触摸来传达情感。我们的系统设计、信号处理方法和结果可以为未来介导的社交触摸设计提供指导。
Touch as a modality in social communication has been getting more attention with recent developments in wearable technology and an increase in awareness of how limited physical contact can lead to touch starvation and feelings of depression. Although several mediated touch methods have been developed for conveying emotional support, the transfer of emotion through mediated touch has not been widely studied. This work addresses this need by exploring emotional communication through a novel wearable haptic system. The system records physical touch patterns through an array of force sensors, processes the recordings using novel gesture-based algorithms to create actuator control signals, and generates mediated social touch through an array of voice coil actuators. We conducted a human subject study (N = 20) to understand the perception and emotional components of this mediated social touch for common social touch gestures, including poking, patting, massaging, squeezing, and stroking. Our results show that the speed of the virtual gesture significantly alters the participants' ratings of valence, arousal, realism, and comfort of these gestures with increased speed producing negative emotions and decreased realism. The findings from the study will allow us to better recognize generic patterns from human mediated touch perception and determine how mediated social touch can be used to convey emotion. Our system design, signal processing methods, and results can provide guidance in future mediated social touch design.
