Abstract

Several studies in the affective haptics research field showed the potential of using haptic technology to convey emotions in remote communications. In this context, it is of interest to simplify the haptic feedback without altering the informative content of the stimulus, with a two-fold advantage. On one side, it would allow the development of affective haptic devices whose technological complexity is limited, hence more compatible with wearability and portability requirements. On the other side, having a simplified set of stimuli would decrease the amount of data to be transmitted, thus improving the overall quality of remote haptic interactions. In this work, we investigated the correlation between the parameters regulating a caress-like stimulation and the perceived pleasantness. This was done by means of two experiments, in which we asked subjects to adjust the temperature and the motion velocity of a set of stimuli in order to find the most pleasant combination. Results indicated that subjects preferred different values of temperature and velocity of the stimulus depending on the proposed tactile stimulation. A small difference in the pleasantness ratings was observed between caresses provided with linear movements and those given as discrete sequences of taps. In particular, participants preferred linear movements set at

$34.5 \,^{\circ }\mathrm{C}$

and

$3.4 \,\mathrm{c}\mathrm{m}\mathrm{s}^{-1}$

. As regards caress-like stimuli provided with discrete sequences of taps, the preferred temperature and velocity were

$33.2 \,\mathrm{^{\circ }C}$

and

$2.9 \,\mathrm{c}\mathrm{m}\mathrm{s}^{-1}$

, respectively. The presence of vibration had a little effect on the perceived pleasantness.

触觉刺激与愉悦感的相关性研究。

情感触觉研究领域的几项研究表明，使用触觉技术在远程通信中传达情感具有潜力。在这种情况下，有兴趣在不改变刺激的信息内容的情况下简化触觉反馈，这具有双重优势。一方面，它将允许开发技术复杂性有限的情感触觉设备，因此更符合可穿戴性和便携性要求。另一方面，具有一组简化的刺激将减少要传输的数据量，从而提高远程触觉交互的整体质量。在这项工作中，我们研究了调节爱抚样刺激的参数与感知愉悦感之间的相关性。这是通过两个实验完成的，在这两个实验中，我们要求受试者调整一组刺激的温度和运动速度，以找到最令人愉快的组合。结果表明，受试者根据所提出的触觉刺激偏好不同的刺激温度和速度值。在以线性动作提供的爱抚和以离散的轻拍序列提供的爱抚之间，观察到愉悦度评级的微小差异。特别是，参与者更喜欢34.5°C和3.4 cm-1的线性运动。对于由离散敲击序列提供的类似爱抚的刺激，优选的温度和速度分别为33.2°C和2.9 cm-1。振动的存在对感知到的愉悦感影响不大。

期刊介绍： IEEE Transactions on Haptics (ToH) is a scholarly archival journal that addresses the science, technology, and applications associated with information acquisition and object manipulation through touch. Haptic interactions relevant to this journal include all aspects of manual exploration and manipulation of objects by humans, machines and interactions between the two, performed in real, virtual, teleoperated or networked environments. Research areas of relevance to this publication include, but are not limited to, the following topics: Human haptic and multi-sensory perception and action, Aspects of motor control that explicitly pertain to human haptics, Haptic interactions via passive or active tools and machines, Devices that sense, enable, or create haptic interactions locally or at a distance, Haptic rendering and its association with graphic and auditory rendering in virtual reality, Algorithms, controls, and dynamics of haptic devices, users, and interactions between the two, Human-machine performance and safety with haptic feedback, Haptics in the context of human-computer interactions, Systems and networks using haptic devices and interactions, including multi-modal feedback, Application of the above, for example in areas such as education, rehabilitation, medicine, computer-aided design, skills training, computer games, driver controls, simulation, and visualization.
