Abstract

Tosolve complex and diverse social problems and ensure the quality of life of individuals, social robots that can interact with humans are attracting attention. In the past, robots were recognized as beings that provide labor force as they put into industrial sites on behalf of humans. However, the concept of today's robot has been extended to social robots that coexist with humans and enable social interaction with the advent of Smart technology, which is considered an important driver in most industries. Specifically, there are service robots that respond to customers, the robots that have the purpose of edutainment, and the emotionalrobots that can interact with humans intimately. However, popularization of robots is not felt despite the current information environment in the modern ICT service environment and the 4th industrial revolution. Considering social interaction with users which is an important function of social robots, not only the technology of the robots but also other factors should be considered. The design elements of the robot are more important than other factors tomake consumers purchase essentially a social robot. In fact, existing studies on social robots are at the level of proposing "robot development methodology" or testing the effects provided by social robots to users in pieces. On the other hand, consumer emotions felt from the robot's appearance has an important influence in the process of forming user's perception, reasoning, evaluation and expectation. Furthermore, it can affect attitude toward robots and good feeling and performance reasoning, etc. Therefore, this study aims to verify the effect of appearance of social robot and consumer emotions on consumer's attitude toward social robot. At this time, a social robot design evaluation model is constructed by combining heterogeneous data from different sources. Specifically, the three quantitative indicator data for the appearance of social robots from the ABOT Database is included in the model. The consumer emotions of social robot design has been collected through (1) the existing design evaluation literature and (2) online buzzsuch as product reviews and blogs, (3) qualitative interviews for social robot design. Later, we collected the score of consumer emotions and attitudes toward various social robots through a large-scale consumer survey. First, we have derived the six major dimensions of consumer emotions for 23 pieces of detailed emotions through dimension reduction methodology. Then, statistical analysis was performed to verify the effect of derived consumer emotionson attitude toward social robots. Finally, the moderated regression analysis was performed to verify the effect of quantitatively collected indicators of social robot appearance on the relationship between consumer emotions and attitudes toward social robots. Interestingly, several significant moderation effects were identified, these effects are visualized with two-way interaction effect to interpret them from multidisciplinary perspectives. This study has theoretical contributions from the perspective of empirically verifying all stages from technical properties to consumer's emotion and attitudes toward social robots by linking the data from heterogeneous sources. It has practical significance that the result helps to develop the design guidelines based on consumer emotions in the design stage of social robot development.

최근 인간과 상호작용할 수 있는 '소셜로봇'을 활용하여 복잡하고 다양한 사회문제를 해소하고 개인의 삶의 질을 제고하려는 시도가 주목받고 있다. 과거 로봇은 인간을 대신해서 산업 현장에 투입되고 노동력을 제공해주는 존재로 인식되었다. 그러나 오늘날의 로봇은 각종 산업분야를 관통하는 핵심 키워드인 'Smart'의 등장을 기점으로 인간과 함께 공존하며 사회적 교감이 가능한 '소셜로봇(Social Robot)'으로 그 개념이 확장되고 있다. 구체적으로 고객을 응대하는 서비스 로봇, 에듀테인먼트(Edutainment) 성격의 로봇, 그리고 인간과의 교감, 상호작용에 주목한 감성로봇 등이 출시되고 있다. 그러나 4차 산업혁명을 계기로 ICT 서비스 환경이 급격한 발전을 이룬 현재까지 소셜로봇의 대중화는 체감되지 않고 있다. 소셜로봇의 핵심 기능이 사용자와의 사회적 교감임을 고려하면, 소셜로봇의 대중화를 촉진하기 위해서는 기기에 적용되는 기술 이외의 요소들도 중요하게 고려할 필요가 있다. 본 연구는 로봇의 디자인 요소가 소셜로봇에 대한 소비자들의 구매를 이끌어내는데 중요하게 작용할 것으로 판단한다. 로봇의 외형이 유발하는 감성은 사용자의 인지, 추론, 평가와 기대를 형성하는 과정에서 중요한 영향을 미치며 나아가 로봇에 대한 태도와 호감 그리고 성능 추론 등에도 영향을 줄 수 있다. 그러나 소셜로봇에 대한 기존 연구들은 로봇의 개발방법론을 제안하거나, 소셜로봇이 사용자에게 제공하는 효과를 단편적으로 검증하는 수준에 머무르고 있다. 따라서 본 연구는 소셜로봇의 외형으로부터 사용자가 느끼는 감성이 소셜로봇에 대한 사용자의 태도에 미치는 영향을 검증해보고자 한다. 이때 서로 다른 출처의 이종 데이터 간 결합을 통하여 소셜로봇 디자인평가 모형을 구성한다. 구체적으로 소셜로봇의 외형에 대하여 사전에 구축된 ABOT Database로부터 다수의 소셜로봇에 대한 세 가지 정량적 지표 데이터를 확보하였다. 소셜로봇의 디자인 감성은 (1) 기존의 디자인평가 문헌과 (2) 소셜로봇 제품 후기와 블로그 등의 온라인 구전, (3) 소셜로봇 디자인에 대한 정성적인 인터뷰를 통해 도출하였다. 이후 사용자 설문을 통하여 각각의 소셜로봇에 대해 사용자가 느끼는 감성과 태도에 대한 평가를 수집하였다. 세부적인 감성 평가항목 23개에 대하여, 차원 축소 방법론을 통해 6개의 감성 차원을 도출하였다. 이어서 도출된 감성 차원들이 사용자의 소셜로봇에 대한 태도에 미치는 영향을 검증하기 위해 회귀분석을 수행하여 감성과 태도 간의 관계를 파악해 보았다. 마지막으로 정량적으로 수집된 소셜로봇의 외형에 대한 지표가 감성과 태도 간의 관계에 영향을 줄 수 있음을 검증하기 위해 조절회귀분석을 수행하였다. 기술적인ABOT Database 속성 지표들과 감성 차원들 간의 순수조절효과를 확인하고, 도출된 조절효과에 대한 시각화를 수행하여 외형, 감성, 그리고 태도 간의 관계를 다각적인 관점에서 해석하였다. 본 연구는 이종간 데이터를 연결하여 소셜로봇의 기술적 속성과 소비자 감성, 태도까지 변수 간 관계를 총체적으로 실증 분석했다는 점에서 이론적 공헌을 가지며, 소셜로봇 디자인 개발 전략에 대한 의사결정을 지원하기 위한 기준으로 소비자 감성의 활용 가능성을 제안하였다는 실무적 의의를 가진다.
