Experimental Study on Abstract Expression of Human-Robot Emotional Communication

Abstract

With the continuous development of intelligent product interaction technology, the facial expression design of virtual images on the interactive interface of intelligent products has become an important research topic. Based on the current research on facial expression design of existing intelligent products, we symmetrically mapped the PAD (pleasure–arousal–dominance) emotion value to the image design, explored the characteristics of abstract expressions and the principles of expression design, and evaluated them experimentally. In this study, the experiment of PAD scores was conducted on the emotion expression design of abstract expressions, and the data results were analyzed to iterate the expression design. The experimental results show that PAD values can effectively guide designers in expression design. Meanwhile, the efficiency and recognition accuracy of human communication with abstract expression design can be improved by facial auxiliary elements and eyebrows.

Design of Proactive Interaction for In-Vehicle Robots Based on Transparency

“…The vehicle robot had three degrees of freedom and was controlled by servos that can raise and lower its head and rotate toward the driver. The robot’s face screen displayed features and colorful auxiliary graphics to express expressions, which was in-depth explored and designed in our previous research [ 39 ]. The expression design was shown in Figure 6 , in which the color and brush strokes were adjusted due to the confidentiality of company cooperation.…”

Exploring the Design Space of Extra-Linguistic Expression for Robots

“…For example, Sanda and Kanoh [41] applied Japanese comic art techniques (called Manpu) of line and shadows into facial expression design for a welfare robot. Wang et al [64] designed comic-style facial expressions for robots to investigate abstract expression for human-robot emotional interaction.…”

Creating the optimal design approach of facial expression for the elderly intelligent service robot

“…With the face as the core expression, the expression of a robot can mainly convey emotions that satisfy functionality and creating a relaxed and pleasant atmosphere (Wang,Wang,Liu,Yue,Wang,Yang,Hansen and You, 2021). In study of the design elements of virtual facial interaction expressions for robots, the eyes are the organ that directly reflects a person emotions, and the direction of the eye gaze conveys the focus of the vision and shows the motivation of their behaviour.…”

“…Otherwise, when the mouth is turned downwards, it shows negative emotions such as sadness, shame and hostility. Moreover, the eyebrows are particularly important for perceiving the user's emotions (Wang,Wang,Liu,Yue,Wang,Yang,Hansen and You, 2021), and the type of facial expression action depends heavily on the dynamics of the eyebrows.…”
