본 연구는 사용자에게 친숙한 (user-friendly) 뮤직폰을 디자인하기 위하여, 실제 사용자들을 대상으로 일반적인 음악에 대한 경험 및 뮤직폰을 비롯, MP3 플레이어와 같은 포터블 뮤직 디바이스에 대한 경험을 조사 분석한 것이다. 조사 방법으로는 Focus Group Interview 와 설문이 사용되었으며, 한국을 포함하여 일본, 미국, 영국, 이탈리아 등 5개국 사용자들을 대상으로 동시에 실시되었다. 각 지역의 서로 다른 사용자 특성을 비교 분석하기 위하여 모두 동일한 진행 방법 및 조사 문항을 이용하였다. 대상자는 뮤직폰의 목표 사용자층을 고려하여 각국에서 2~30대의 남녀 5~8명을 선정하였다. 조사 결과, 5개국 공통으로 존재하는 사용자 경험 및 요청사항이 다수 발견되었으며, 이를 통해 뮤직에 대한 경험이 매우 보편적인 경험임을 확인하였다. 음악에 대한 경험에서는 PC를 음악 파일 저장 및 관리에 사용하는 관리 행태가, 뮤직폰에 대해서는 하드웨어적인 향상 니즈가 대표적인 공통점이었다. 또한, 자주 사용하는 기능이나 선호하는 인터랙션에 있어서는 국가 간, 지역 간 공통점과 함께 차이점도 발견되었다. 본 연구는 이러한 조사 결과를 분석하고, 이를 바탕으로 뮤직폰의 사용자 경험을 향상시킬 수 있는 가이드를 제시하고자 한다.

본 논문에서는 커넥티드 카 서비스의 사용자경험 디자인을 위한 평가 요인을 제안한다. 모바일 및 IoT기술의 발전과 더불어 자율주행 자동차에 대한 관심이 증가하고 있는 가운데 네트워크와의 연결을 통한 다양한 디지털서비스 제공 플랫폼 경쟁이 가속화되고 있다. 플랫폼 개발을 위한 기술적 연구는 빠르게 진행되고 있으나 실재 서비스 소비의 주체인 사용자 관점에서의 연구는 아직 미비하다. 경쟁이 가속화 될수록 커넥티드 카 구현 기술은 평중화될 것으로 예상되어 결국 커넥티드 카 서비스의 핵심 쟁점은 주행 중 서비스 사용자의 긍정적 경험이 될 것으로 예측된다. 따라서 본 논문에서는 커넥티드 카에서 제공되는 기능과 이에 따른 주요 서비스 요인들을 살펴보고 자동차 구매에 영향을 미치는 사용자경험 요인을 도출하여 둘의 상관관계를 실증적으로 분석함으로써 앞으로 등장할 차세대 커넥티드 카 서비스 및 플랫폼의 사용자 경험평가 요인을 도출하고자 한다.

This study conducted user experience evaluation by introducing various text mining techniques along with topic modeling techniques for mobile menstrual cycle measurement applications that are closely related to women's health and analyzed the results by combining them with a honeycomb model. To evaluate the user experience revealed in the menstrual cycle measurement application review, 47,117 Korean reviews of the menstrual cycle measurement application were collected. Topic modeling analysis was conducted to confirm the overall discourse on the user experience revealed in the review, and text network analysis was conducted to confirm the specific experience of each topic. In addition, sentimental analysis was conducted to understand the emotional experience of users. Based on this, the development strategy of the menstrual cycle measurement application was presented in terms of accuracy, design, monitoring, data management, and user management. As a result of the study, it was confirmed that the accuracy and monitoring function of the menstrual cycle measurement of the application should be improved, and it was observed that various design attempts were required. In addition, the necessity of supplementing personal information and the user's biometric data management method was also confirmed. By exploring the user experience (UX) of the menstrual cycle measurement application in-depth, this study revealed various factors experienced by users and suggested practical improvements to provide a better experience. It is also significant in that it presents a methodology by combines topic modeling and text network analysis techniques so that researchers can closely grasp vast amounts of review data in the process of evaluating user experiences.

As digital transformation accelerates, the proportion of non-face-to-face services in financial services is also increasing. Recently, user experience has emerged to secure competitiveness in mobile services, and analysis techniques to improve user experience have emerged. User review data, one of the data used for quantitative evaluation, contains a lot of unnecessary information, which is time-consuming to derive improvement directions. Therefore, this study aims to develop a UX analysis system based on the hierarchy of UX needs by using a cosine similarity algorithm and analyze user review data of Kookmin Bank, Woori Bank, Kakao Bank, and Toss for verification. This study proved that the developed UX analysis system is a system that can effectively analyze UX through the analysis of user review data. The system of this study is expected to be easily used to identify improvement plans for the hierarchy of UX needs in an agile organization that needs to quickly reflect customer feedback.

With the rapid advancement of generative artificial intelligence technology, there is growing interest in how to utilize it in practical applications. Additionally, the importance of prompt engineering to generate results that meet user demands is being newly highlighted. Exploring the new possibilities of generative AI can hold significant value. This study aims to utilize ChatGPT 4.0, a leading generative AI, to propose an effective method for evaluating user experience through the analysis of online customer review data. The user experience evaluation method was based on the six-layer elements of user experience: 'functionality', 'reliability', 'usability', 'convenience', 'emotion', and 'significance'. For this study, a literature review was conducted to enhance the understanding of prompt engineering and to grasp the clear concept of the user experience hierarchy. Based on this, prompts were crafted, and experiments for the user experience evaluation method were carried out using the analysis of collected online customer review data. In this study, we reveal that when provided with accurate definitions and descriptions of the classification processes for user experience factors, ChatGPT demonstrated excellent performance in evaluating user experience. However, it was also found that due to time constraints, there were limitations in analyzing large volumes of data. By introducing and proposing a method to utilize ChatGPT 4.0 for user experience evaluation, we expect to contribute to the advancement of the UX field.

As music streaming services (MSS) involve various interactions with users during the music consumption process, it is important to understand the user experience and manage the service accordingly. This study developed a user experience model for MSS by theoretically linking the quality characteristics considered important by music service users with the structure of user experience. PLS analysis was then performed using survey data to test the model. As a result, functionality (search, browsing, and personalized recommendation), UI usability, content quality (currentness, sufficiency, relevance), and monetary cost were found to be key experience factors that determine the experience consequence, i.e., user satisfaction. In addition, in a supplementary analysis comparing domestic and global services, differences in user experience were found between the two groups in terms of functionality and content quality. The user experience model of MSS proposed in this study serves as a new foundation for theory-based research in this field and provides meaningful implications for the competitive landscape among music streaming service platforms and for their competitive strategies.

This study is a case analysis for user interface(UI) design of spectrophotometer which is widely used in the field of chemistry, biology and environment, based on user experience(UX). Generally, experimental equipment developments are centered on functionality and technology, and the interface for interaction between the user and the machine is developed only by the engineers who do not have much consideration for the users. From this background, this study tried to find out how UX could melt into UI so that a kind of spectrophotometers can be designed to help the work process of researchers in the real context by examining and analyzing the real users' experiences and also considering the developer's perspective. As a result, it was possible to improve UI and was found that redefinition of the goal of UI, time-efficiency, security, and sufficient information delivery are essential to the design of user interface for spectrophotometers.
