ABSTRACT

The present aim was to investigate if angry, neutral, and happy facial expressions have different effects on haptic responses. Two experiments were conducted. In Experiment 1, participants (N = 24) were to respond as fast as they could to images of angry, neutral, and happy faces using a haptic device that measured the amount of applied force in newton units and the duration of touch in milliseconds. Experiment 2 was identical to Experiment 1, except that ratings of emotion-related experiences evoked by the stimuli were also collected in terms of valence and arousal. The results from both studies showed that the force of touch in response to angry expressions was significantly stronger than in response to happy expressions. The ratings of valence showed that angry, neutral, and happy faces were experienced statistically significantly different from each other along the dimension of valence. Ratings of arousal showed that angry faces were experienced as significantly more arousing than neutral and happy faces. The results suggest a relationship between the processing of emotion-related facial expressions and haptic response systems. The force of touch could be used as one of the measures conveying information about the user’s state of mind when interacting with haptic user interfaces.

摘要

目前的目的是调查愤怒、中性和快乐的面部表情是否对触觉反应有不同的影响。进行了两个实验。在实验 1 中，参与者 (N = 24) 将使用触觉设备尽可能快地对愤怒、中立和快乐的面孔做出反应，该设备以牛顿为单位测量施加的力的大小，并以毫秒为单位测量触摸的持续时间。实验 2 与实验 1 相同，不同之处在于刺激引起的情绪相关体验的评级也收集在效价和唤醒方面。两项研究的结果都表明，对愤怒表情的反应力度明显强于对快乐表情的反应。效价评级显示愤怒、中立、和快乐的面孔在效价维度上具有统计学上的显着差异。唤醒度评级表明，愤怒的面孔比中性和快乐的面孔更容易唤醒。结果表明情绪相关面部表情的处理与触觉反应系统之间存在关系。当与触觉用户界面交互时，触摸力可以用作传达有关用户心理状态信息的措施之一。
