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

Abstract

In order to explore the aging-friendly design features of the facial expression interface of the elderly intelligent robot and reduce the cognitive burden of the elderly users, an optimal design method for the facial expression interface of the elderly intelligent service robot based on the user's emotional experience is proposed. Firstly, based on the PAD (Pleasure-Arousal-Dominance) emotion model, the recognition rate and satisfaction of the elderly users on the expression design style of the elderly intelligent service robot are tested, so as to explore the rules that affect the acceptance and emotional satisfaction of the elderly to the facial expression interaction. Secondly, in view of the PAD scale scores of 8 expression design schemes, the emotional tendency of the expression design scheme is obtained through the calculation of space distance. Finally, through the iteration of the design scheme, the improvement of the expression design scheme is completed, and these design solution is also validated by emotional tendency measure based on the PAD model. According to the experimental results, the PAD emotion model can effectively explore the characteristics and rules of the expression interaction design of intelligent service robots suitable for elderly, so as to accurately map the real emotional experience of the elderly. Furthermore, the PAD model can effectively guide designers to quickly and conveniently design and optimize the design scheme that meet user demands.
