Adriance Wilfred,Minjee Kim,Sungho Kim,Chan Hyeok Yun,NamWoo Cho,Jane Lee,Soo Yeon Kim,Joong Hee Lee,Kyung-Jun Lee,Myung Hwan Yun 한국HCI학회 2021 한국HCI학회 학술대회 Vol.2021 No.1
This paper presents an investigation of UX factor of a voice user interface (VUI) for the elderly, where the voice user interface in this study refers to the artificial intelligence (AI) based technology that interacts with a user via speech commands. In this research, the investigation of UX factors involves the acceptance and affective aspects of the elderly. We applied the Wizard-of-Oz methodology in this experiment, and established our result using Exploratory Factor Analysis (EFA) which determines the significant elements of user experience in voice user interface. Overall, the extracted UX factors can be regard as relevant design parameters for future voice user interface system and researches.

Objective: This research aims to investigate the user experience (UX) factors in the usage of e-scooter sharing system to aid the stakeholders to establish a sharing system which satisfies their e-scooter users. Background: The user population of e-scooters has rapidly increased 6 times in a single year from 2020 to 2021 in the Republic of Korea. E-scooter sharing system is expected to resolve traffic issues in metropolises. Furthermore, some countries borrowed and implemented the policies of car-sharing service for the e-scooter system in order to encourage the use of personal mobility device (PMD) when commuting in short distances. However, such policies are not directly applicable due to the differences in various contextual factors such as user characteristic, terrains, and products form factors. Therefore, there were insufficient research investigating the UX factors of e-scooter sharing system. Method: We conducted an online user survey with 42-item questionnaire which include items about pragmatic and hedonic qualities. All questionnaires were retrospective. A total of 315 participants (159 females and 156 males) residing in Seoul, who has experience in using e-scooter sharing systems participated in the survey. We conducted the Exploratory Factor Analysis (EFA) using IBM SPSS Statistics 26 software to determine and extract the significant UX factors. Results: The result of the analysis showed 9 UX factors, accounting for 74.771% of the variance. The extracted factors are as follows: (1) Ecological-and-Economical Friendly, (2) User Attitude and Engagement, (3) Perceived Usefulness, (4) Privacy and Security, (5) Perceived Ease-of-Use, (6) Tech-Enthusiastic, (7) Safety Concerns, (8) Environmental Concerns, and (9) Accessibility (Availability). Each factor showed reliable Cronbach’s alpha value of above 0.779. Conclusion: This study was able to identify 9 UX factors for e-scooter sharing systems. We expect there will be more increasing number of significant UX factors as the future of e-scooter sharing systems improve over the time. Application: Based on these results, we expect these findings would benefit and assist the designers and developers of the e-scooter sharing system in the future by considering the extracted UX factors.

Objective: The purpose of this study is to design and develop a prototype of a support tool system for user experience (UX) designers to evaluate the UX of personal mobility devices (PMD) more effectively and efficiently. Background: Traffic problems continues to rise as the complexity of the transportation system grows. One of the solutions being employed to solve such issues is the use of personal mobility devices (PMD). PMDs are suitable for traveling at a faster speed and a more flexible route. Although the usage of PMDs continues to increase, there is still a lack of research with regards to the UX of PMDs due to characteristics of the device which is different from the conventional transport systems. Thus, a support tool to help UX designers specifically evaluate PMDs is essential. Method: The methodology for this study can be classified into three stages: research, ideation and prototyping. For the research stage, a review of the literature was conducted to collect information about how PMDs are being evaluated in terms of UX and to determine any gaps in the literature. After that, during the ideation stage, the results of the review were organized, and the hierarchy of information was structured based on multiple brainstorming sessions by the UX researchers. The brainstorming sessions also involved different design thinking techniques such as creating conceptual maps and flowcharts. Lastly, on the prototyping stage, low-fidelity and high-fidelity prototypes were developed to test and show the information architecture of the system. Results: The final prototype of the support tool system was created. The main features that were included in the system were: UX evaluation database, UX evaluation guide, and UX testing. Conclusion: This study developed a support tool for UX designers to help them better evaluate the UX specifically for PMDs. Application: The prototype of the system designed in this study can contribute to improving the efficiency and effectiveness of UX evaluation specifically for PMDs with further development and evaluation.

개인형 이동수단의 사용자 경험 평가 사례 데이터베이스 구축
김성호(Sungho Kim),엘라(May Jorella Lazaro),이재인(Jane Lee),에드리안(Adriance Wilfred),허정(Jeong Heo),하성윤(Seung Yun Ha),윤명환(Myung Hwan Yun) 대한인간공학회 2021 대한인간공학회 학술대회논문집 Vol.2021 No.11
Objective: 본 연구는 개인형 이동수단의 체계적인 사용자 경험 평가를 위한 기초 데이터베이스를 구축하는 것이다. Background: 거대 도시화 및 사회 고령화 등 빠른 속도로 변화하는 다양한 사회 현상은 이동수단 패러다임의 근본적 변화를 초래하고 있다. 특히, 이동 목적 및 이동 거리에 따라 개인형 이동수단을 포함한 교통수단의 환승형 복합 활용이 일반화될 것으로 예상되고 있다. 이러한 상황 하에서 사용자들의 개인형 이동수단 이용에 대한 새로운 경험을 효과적으로 이해하기 위해서는 적합한 평가 기준 및 방법의 적용이 중요하다. Method: 본 연구는 데이터베이스 구축을 위해 문헌 조사와 실험 수행을 통해 사용자 경험 평가 사례 데이터를 수집하였다. 문헌 조사 데이터는 SCOPUS, WEB OF SCIENCE, SCIENCE DIRECT, IEEE 등과 같은 검색 엔진을 활용하여 개인형 이동수단과 사용자 경험과 관련된 키워드 조합을 통해 수집되었다. 실험 수행 데이터는 개인형 이동수단 관련 주요 사용자 경험 요소에 대한 사전 평가, 인간공학 장비를 활용한 사용자 경험 평가 방법론 개발 등의 목적으로 수행된 실험 수행을 통해 수집되었다. Results: 평가 사례 데이터 수집 결과, 개인형 이동수단의 사용자 경험을 대상으로 연구한 문헌 조사 및 실험 수행 사례 총 22건을 수집하였으며, 그 중 문헌 조사는 12건이고 실험 수행은 10건으로 나타났다. 한편, 수집된 사례 데이터를 바탕으로 1) 미래형 이동수단, 2) UX 평가 지표, 3) 평가 방법, 4) 평가 척도, 5) 평가 도구, 6) 분석 방법의 6가지 기준으로 데이터를 분류 및 시각화하였다. Conclusion: 본 연구는 개인형 이동수단의 사용자 경험 평가를 위한 기초 연구로 평가 사례들을 데이터베이스화하였다. Application: 본 연구의 개인형 이동수단 사용자 경험 평가 사례 데이터가 축적된다면, 향후 신규 개발된 개인형 이동수단의 사용자 경험 평가 시 기준 데이터로써 활용될 수 있다.
