The use of service robots, particularly guide robots, is becoming increasingly prevalent in public institutions. However, there has been limited research into the interactions between users and guide robots. To explore the customer experience with the guidance robot, we selected 'QI', which has been meeting customers for the longest time, and collected all reviews since the service was launched in public institutions. By using text mining techniques, we identified the main keywords and user experience factors and examined factors that hinder user experience. As a result, the guide robot's functionality, appearance, interaction methods, and role as a cultural commentator and helper were key factors that influenced the user experience. After identifying hindrance factors, we suggested solutions such as improved interaction design, multimodal interface service design, and content development. This study contributes to the understanding of user experience with guide robots and provides practical suggestions for improvement.

In December 2014, Livestock and Livestock Products Traceability Act was established, allowing consumers to receive livestock traceability information. While the Livestock Traceability System provides consumers with transparent and fair information about their food, it has brought increased workload and penalty burdens to stakeholders in the livestock industry. In this paper, we propose an IoT system for inventory management based on traceability numbers to enable sellers to conveniently provide livestock traceability information to consumers. We analyzed the protocol for managing data from electronic scales and conducted functional testing and verification on mobile devices. Furthermore, we implemented the design and system functionality, taking into account UI/UX on Android OS-based devices to synchronize and interconnect traceability and product information with electronic scales. We anticipate that the proposed approach will minimize user inconvenience and raise production efficiency in the existing market.

Currently, ICT is widely used in caring for the elderly living alone and preventing the disappearance of the elderly with dementia. Therefore, in this study, based on the government policy direction for the 4th industrial revolution, the use of AI technology-based care services, which are gradually increasing in community care, was sought to explore the current status and prospects for utilization and activation.AI speakers and caring robots, services that can be used for community care, help solve various problems experienced by the elderly, and are also used to relieve lack of conversation or loneliness by adding emotional functions. In order to activate community care using AI technology in the future: First, there is a need for continuous education to familiarize the elderly with AI devices and 'user experience (UX) design' for the elderly. Second, it is necessary to use human-centered technology that has a complementary relationship and enables emotional mutual relationships rather than using function-oriented technology. Third, it is necessary to solve ethical problems such as guaranteeing the user's right to self-determination and protecting privacy.

This study aimed to improve the EPL education platform, Rewond (rewond.com), which was built as a prototype, into an EPL educational tool based on Embodied Cognition. In the first phase, the heuristic evaluation, five experts were selected to evaluate the subject using evaluation items that included learning principles of Embodied Cognition. Based on the evaluation results, debriefing session analysis, and consultations with co-researchers, three improvement points were identified and specific modification plans were proposed. During the beta version development phase, the co-researchers implemented an increase in coding content, provided help for each content, and added a feature that allows progression to the next learning stage upon completion of the previous one. In the final usability testing phase, the usability of the beta version was tested with ten fourth-grade elementary school students.

웹 2.0시대의 도래는 데이터의 소유자나 독점자 없이 누구나 손쉽게 데이터를 생산하고 공유할 수 있고, 서비스 받을 수 있는 환경이 마련되었다. 인터넷의 급속한 발전으로 인해 스마트 교육시장이 유망 분야로 주목받는 가운데 교육현장에서도 스마트 러닝에 대한 관심도 또한 높아지고 있다. 기존의 데스크톱, 태블릿 PC를 통해 학습을 하던 환경에서 벗어나 이제는 스마트폰을 기반으로 하는 스마트 러닝이 교육환경을 보편적으로 접하게 되었다. 본 연구에서는 사용자 경험의 UX(User eXperience) 디자인을 바탕으로 어떠한 환경에서도 스마트 러닝이 가능한 웹사이트를 워드프레스 플랫폼으로 구현하고자 한다. 또한 본 웹사이트를 다양한 디바이스에서 테스트를 통해 스마트 러닝이 가능한 환경인지를 검증해 본다.

This study analyzes the lobby UI of the baseball manager game based on the mobile platform and proposes an optimized lobby UI. The UI layout-based detailed icons and button interactions in the four game lobbies are compared and analyzed by comparing and analyzing the common points and differences to finally calculate the optimized UI composition. Furthermore, based on the analysis, we intend to propose a lobby UI optimized for user-centered design.

매장의 매출 증가를 위해 고객의 의견을 반영하는 것은 일반적인 마케팅이다. 여러 기관 및 대형 매장에서 고객의 의견을 반영하기 위해 여러 가지 방법을 취하고 있다. 하지만 대형 매장이 아닌 소규모 소상공인의 매장에는 고객의 의견 수집을 위한 고객의 참여 유도가 쉽지 않아 데이터를 모으기가 힘들다. 이런 문제점을 해결하기 위해 본 논문에서는 친근한 디자인과 접근성 좋은 UX를 가진 '소상공인을 위한 고객 의견 수집' 서비스를 모바일 앱 형태로 설계하고 구현했다. 이는 가게에 대한 고객들의 생각을 소상공인들이 직접 예상하고 수렴하여 잠재적인 매출향상에 도움을 주는데 그 목적이 있다.

코로나-19와 미세먼지의 증가로 '반려 식물'과 '플랜테리어'에 대한 수요가 늘고있는 추세이다. 본 논문에서는 화분에 IoT를 접목하여, 스마트 화분을 구현하였다. 사용자 인터페이스를 iOS 앱으로 개발하였으며, 늘어나는 iPhone 사용자들에게 익숙한 UX/UI 디자인으로 구현하였다. 스마트폰 앱과 가정의 화분 서버가 인터넷으로 통신함으로써, 언제 어디서나 화분의 상태를 확인하고, 제어를 할 수 있게 구현하였다. 서버와 화분 모듈이 분리되어, 화분 자체의 크기를 줄였다. 화분 하단에 물통이 존재하여, 배액이 그대로 물통으로 흘러내려오는 순환식 구조를 채택하였기 때문에 '플랜테리어'에 적합한 모듈이 될 수 있을 것으로 기대한다.

Menopausal women have to care for their health. Menopause is a symptom that needs to be managed in the long term, which requires safe and economical treatment even after long term use. This study proposes digital-based exercise therapy. This study also suggests resistance exercise and walking exercise methods according to the proof of previous studies. It provides motivational contents for those who cannot perform regularly. As motivational methods, self-efficacy and narrative-based history methods are accepted. Self-efficacy is improved through voice agents feedback during exercise. Feedback is a type of messages such as encouragement and motivation. The narrative-based history consists of characters of visualization that improves through values, which leveraged by the exercise.
