在这项工作中，我们提出了一种基于弹性织物的新型可穿戴触觉系统，该系统可以在用户前臂上向前和向后移动，从而模拟人类的爱抚。该系统既可以通过调节电机速度来控制“爱抚式”运动的速度，也可以通过调节电机位置来控制“爱抚的强度”，从而控制织物对用户前臂施加的力。除了描述该系统的机械设计和控制外，我们还报告了六名健康参与者进行的心理生理评估测试的初步结果。这种评估的目的是作为一个初步的表征设备的能力，引出实际情绪状态在人类使用不同的速度和爱抚强度的组合。情绪状态是用唤醒和效价来表达的。此外，自主神经系统的激活也通过分析皮肤电反应（EDR）来评估。研究结果显示，被试的唤醒水平与“爱抚强度”、效价水平与“爱抚速度”之间存在显著的相关关系。此外，我们发现，相EDR能够区分愉快和不愉快的刺激。这些初步结果非常令人鼓舞，并证实了该设备在以可控和可穿戴的方式传递情感类触觉刺激方面的有效性。
In this work we present a novel wearable haptic system based on an elastic fabric which can be moved forward and backward over the user forearm thus simulating a human caress. The system allows to control both the velocity of the “caress-like” movement, by regulating motor velocity, and the “strength of the caress”, by regulating motor positions and hence the force exerted by the fabric on the user forearm. Along with a description of the mechanical design and control of the system, we also report the preliminary results of psycho-physiological assessment tests performed by six healthy participants. Such an assessment is intended as a preliminary characterization of the device capability of eliciting tactually emotional states in humans using different combinations of velocity and caress strength. The emotional state is expressed in terms of arousal and valence. Moreover, the activation of the autonomic nervous system is also evaluated through the analysis of the electrodermal response (EDR). The main results reveal a statistically significant correlation between the perceived arousal level and the “strength of the caress” and between the perceived valence level and the “velocity of the caress”. Moreover, we found that phasic EDR is able to discern between pleasant and unpleasant stimuli. These preliminary results are very encouraging and confirm the effectiveness of this device in conveying emotional-like haptic stimuli in a controllable and wearable fashion.
