在人机交互领域，为了利用人类与生俱来的交流能力，研究者们目前将研究重点放在了促进人与机器人交流的面部表情上。然而，为了让机器人表达情感强度，还需要其他形式，如手势、动作、声音和颜色。本文提出可以通过颜色和闪烁来表达情感的强烈程度，并通过LED应用于机器人。虽然颜色与情绪之间存在一定的关系，但由于缺乏定量数据，以往在这一领域的研究结果难以实施。本文根据定量数据，确定颜色和眨眼周期的RGB值，有效表达六种基本情绪的强度。颜色和闪烁是在角色上实现的，情感强度是通过对角色的调查来评估的。研究发现，颜色和眨眼有助于化身表达惊讶、快乐、厌恶和愤怒等情感强度。对于恐惧和悲伤，颜色和眨眼没有起到重要作用。
In the field of HRI, to take advantage of peoplepsilas innate ability of communication, researchers have thus far concentrated on facial expression in facilitating human robot communication. However, for the robot to express emotional intensity, other modalities such as gestures, movement, sound, and color are also needed. This paper suggests that the intensity of emotion can be expressed with color and blinking, which are applicable on robots via LED. Although color and emotion have certain relations, it is difficult to implement the findings of previous research in this area due to a lack of quantitative data. In this paper, we determined RGB values of color and blinking period to effectively express intensities of six basic emotions based on quantitative data. Color and blinking are implemented on an avatar and the intensities of emotions are evaluated through surveys with the avatar. It was found that color and blinking helped the avatar express emotional intensity of surprise, happiness, disgust, and anger. For fear, and sadness, the color and blinking did not play a significant role.
