Abstract

In the context of the increasing applications of voice assistants in vehicles, we focused on the association between the visual appeal of the cars and the acoustic characteristics of the voice assistants. This study aimed to investigate the relationship between the visual appeal of the vehicle and the voice assistant based on their emotional characteristics. A total of 15 adjectives were used to assess the emotional characteristics of 12 types of cars and six types of voices. An online interview was carried out, instructing participants to match three adjectives with the presented car images or voices. This was followed with a brief interview to allow the participants to reflect on the adjective matches. Based on the assessments, we performed principal component analysis (PCA) to determine factors. We aimed to deploy the cars and voices and analyze the patterns of clustering. The PCA analysis revealed two factors profiled as "Light-Heavy" and "Comfortable-Radical." Both car and voice stimuli were deployed in a two-dimensional space showing the internal relationship within and between the two substances. Based on the coordination data, a hierarchical cluster grouped the 18 stimuli into four groups labeled as challenge, elegance, majesty, and vigor. This study identified two latent factors describing the emotional characteristics of both car images and voice types clustered into four groups based on their emotional characteristics. The coherent matches between car style and voice type are expected to address the design concept more successfully.

음성 어시스턴트가 차량에 탑재되기 시작하면서, 차량의 조형적 특징과 음성 어시스턴트간의 연관성이 중요해지고 있다. 본 연구는 자동차에 적용된 음성 어시스턴트와 외관의 조화스러움에 대하여 공통된 감성적 특징을 기반으로 살펴보고자 하였다. 12가지 차량 이미지와 6가지의 음성 어시스턴트에 대해 15종의 형용사를 바탕으로 감성 평가를 실시하였다. 실험은 온라인 개별 인터뷰로 진행되었으며, 총 24명의 대학생이 참여하였다. 참여자들은 각 자극물을 대표하는 감성 형용사 3종을 1, 2, 3위로 평가하고, 선정 이유에 대한 간단한 인터뷰를 진행하였다. 설문 결과에 대해 주성분분석을 수행하여 2개의 주요 요인을 추출한 뒤, 각 요인을 축으로 하여 자극물을 분포시켰다. 분포도를 바탕으로 감성적 특징을 도출하고자 계층적 군집 분석을 수행하였다. 주성분 분석 결과 자동차 이미지와 음성 어시스턴트를 설명하는 감성적 차원으로 "편안한-급진적인"과 "가벼운-무거운"이 추출되었다. 두 차원을 바탕으로 자극물들을 분포시킨 결과, 자동차와 음성 어시스턴트가 동일한 축을 바탕으로 다양하게 분포해 두 요인이 자극물간 감성적 특징을 도출하기에 적합하다고 판단되었다. 자극물들의 분포도를 바탕으로 계층적 군집분석을 수행하여 17개의 자극물을 4가지 군집으로 추렸다. 각 군집은 도전적인, 우아한, 위엄있는, 활기찬 그룹으로 도출되었다. 본 연구에서는 차량의 조형적 특징과 음성 어시스턴트의 감성적 이미지를 동시에 설명할 수 있는 두 축을 도출하였다. 도출된 축을 바탕으로 그려진 분포도에 군집 분석을 수행해 감성적 특징을 분류하였으며, 총 4개의 감성적 특징이 도출되었다. 본 연구는 자동차의 조형적 특징에 맞춘 음성 어시스턴트 제안을 위한 디자인 품평 가이드로 활용되어, 추후 출시되는 차량에서 사용자들의 자동차 음성 어시스턴트 감성 경험이 증진될 것으로 기대한다.
