자연스러움 개념에 관한 탐색적 연구

국문 초록 (Abstract)

자연스러움은 엔터테인먼트 분야를 비롯해 HCI와 HRI 분야에서 중요하게 논의되는 개념이다. 그러나 그 흔한 쓰임에 비해 아직 잘 정의된 바가 없다. 본 연구는 튜링 테스트의 판단 원리를 활용하여 부자연스러움의 속성을 배제하는 방식으로 자연스러움의 속성에 접근하였다. 언캐니 밸리 효과는 부자연스러움 판단의 대표적인 현상으로 잘 알려져 있다. 본 연구는 이를 논의의 시작점으로 삼아 언캐니 반응에 내재한 인지·심리를 파악하고 이를 토대로 자연스러움 개념의 속성에 대해 고찰하였다. 캐릭터나 로봇의 신경 처리 연구에 따르면 언캐니와 같은 부자연스러움에 관한 판단에는 기대 위반, 대상의 불확실함, 집중, 놀라움, 의식과 무의식이 관여하는 것으로 보인다. 언캐니 반응은 나타난 결과가 기대나 예측과 다르거나 확실하게 설명되지 않으면서 유발된 놀라움으로 주의가 집중되고 의식하게 되면서 부정적인 정서로 이어진 결과로 설명될 수 있다. 따라서 새로운 정보가 불확실함 없이 기존의 스키마로 인해 형성된 기대나 예측에 잘 부합될수록 우리는 자연스러움을 느낄 가능성이 크다. 결국 자연스러움은 어떤 대상이나 현상이 그 상태 그대로 받아들여지는 상태로 설명될 수 있다.

다국어 초록 (Multilingual Abstract)

Although the concept of naturalness is considered as an aesthetic goal in the fields of HCI and HRI including the entertainment industry, there is no generally agreed definition. For this reason, this article attempted to conceptualize the notion of naturalness by adapting the methodological approach applied to the Turing test that determines the subject between humans or machines. This study investigated cognitive-psychological factors involved in the uncanny valley effect such as expectation, cognitive biases, uncertainty, surprise, and adaptation based on cognitive neuroscience studies since it is the most representative phenomenon of unnaturalness. In this process, this paper reviewed predictive theories such as predictive coding and the cognitive-evolutionary model of surprise. The findings indicate that naturalness can be conceptualized as the state in which an object or event is considered the way it is.
