Digital Game design with educational purposes and User Experience measurement via game analytics has been extensively covered in literature, however non-digital games such as tabletops in education and its corresponding educational impact have limited research. In this paper, we propose a guideline to create non-digital educational games from scratch and evaluate them based on the know-how of developers and the investigation of scholars who have studied the engagement factors related to the digital games and applied their findings to non-digital games. Along with the guideline we provide an actual implementation, a game called HXGN_766, meant to serve as scaffolding of computational thinking and rudimentary Python programing concepts. We believe both, guideline and game, can be a useful reference for those interested on game design, educational content design, game quality control check, and unplugged computer science activities. This is the first in a series of papers where the game design concept, the evaluation methodology and the game itself will be presented with more detail.

It is very difficult, but important, to induce and maintain voluntary user engagement in content. For example, many Internet contents provide financial rewards for the user's participation and maintenance. However, there are limitations to methods such as stimulating only external motivations, such as monetary rewards, and sophisticated design and management are needed to obtain sustained and voluntary user participation in content. For this purpose, we propose a Gamified CMS that extends the existing Content Management System (CMS) by referring to the example of the Gamified Learning Management System. This will ultimately increase the participation and commitment of users in content.

This study investigates the user experience (UX) of first aid training using virtual reality (VR) technology. As VR continues to be adopted for educational and training purposes, it is important to understand how learners perceive and engage with this medium for developing critical skills, such as first aid. In this study, we developed a VR application called "VR First Aid" that includes training modules on three emergency scenarios: heatstroke, shock, and seizure. The application has both tutorial and hands-on training components. We conducted a UX study by administering a questionnaire to participants. The UX of learning through the VR application was then compared to using a traditional e-book format. Results indicate that participants perceived stronger internal behavior control with the e-book but reported better confirmation, engagement, enjoyment, and intention to use when training with the VR system. Gender differences were also explored, revealing that female participants expressed greater interest in learning through the VR platform compared to male participants. These findings provide insights into the strengths and limitations of VR-based first aid training compared to traditional methods. Implications for the design and deployment of VR training systems are discussed, with a focus on optimizing the learner experience and learning outcomes.

Since the outbreak of COVID-19 in 2019, the pandemic has been prolonged. This study compares and analyzes the degree of social media usage, the information type of posts (infectious disease information, promote action, psychological communication), and the level of user engagement in conducting crisis communication by country. We conduct text analysis by collecting information on Facebook and YouTube posts from January 2020 to March 2021 of disease control and prevention agencies in Korea, US, UK, and EU. As a result, the use of social media in Korea and US is higher than of the UK and EU, and all four countries are using social media as a means to provide infectious disease information and to promote action. Although social media can be a means to reach the public psychologically, such as sympathy and respect, there are no posts of psychological communication type on social media in countries other than the US. User engagement with posts is highest in the promotion action type. This study can help define the importance and role of social media in establishing an infectious disease crisis communication strategy.

This study aims to investigate the influence of engagement of augmented reality game on immersion. The relationship between engagement and flow was examined through the mediating effects of emotional attachment and focus of attention on presence and the mediating effects of presence on flow. In order to verify the research hypothesis, online questionnaire was conducted with the consent of $Pok\acute{e}mon$ Go game user group. The questionnaire items were translated from the Augmented Reality Immersion Questionnaire. A total of 200 questionnaires were collected and used for analysis. Using the SPSS 23.0 program and the Mplus 7.0 program, the reliability of the scale was confirmed through the Cronbach's coefficient and the causal relationship and the mediating effects were verified by path analysis. As a result, there was no direct causal relationship between engagement and flow. However, causal relationship was evident when emotional attachment and focus of attention were mediated in the process of engagement in augmented reality game. In conclusion, systematic explanations of participant's emotional attachment and attentional state as a main factor in the process of participating in the augmented reality game involvement, reveal the elements to be noticed by the augmented reality game.

Objectives: The present study aimed to evaluate the usability, quality, and usefulness of the mobile application, CAMBRA-kids, for caries management in preschoolers. Methods: Ninety-one caregivers and preschoolers participated in the user evaluation of CAMBRA-kids. The evaluators assessed the usability, quality, and usefulness of CAMBRA-kids. The collected data were analyzed using R studio 1.2.1335 for Windows (RStudio Inc. 2018, Boston, MA, USA). The evaluations for usability, quality, and usefulness were analyzed with descriptive statistics, Kruskal-Wallis rank sum test, and Wilcoxon rank sum test. Results: On user evaluation, the quality and usefulness of the application scored >3 points, and majority of the users rated the quality and usefulness of the application as high. The quality of the application's system was the highest at 3.68 points, and the actual usage of the application was the lowest at 3.10 points. The application had the highest technological aspect score of 3.20, whereas the content related to oral health information had the lowest score of 3.10/5. Although the application showed no statistically significant differences in the quality and usefulness according to general characteristics, there was a statistically significant difference (p<0.05) between the two when compared between the caries risk group. For all items, the protector of the high-risk group evaluated the quality and usefulness of the application highly. The moderate risk group gave the lowest evaluation score for the application's quality and usefulness. The usability score of the application, according to the user version of the mobile application rating scale (uMARS), was 3.25, and the average engagement score was 2.82 (56.31%). The highest subscale score was 3.63. Conclusions: In this study, we found suitable quality, usability, and usefulness of the mobile application, CAMBRA-kids. In future, the use of this application will contribute to the prevention of dental caries among preschoolers.

As the number of smart libraries is continuously increasing, activation measures are necessary to expand user engagement and enhance service quality. This study analyzed the usage patterns of four smart libraries in A Library in Incheon, from June 2020 to December 2023. It also conducted user satisfaction surveys and question-and-answer sessions with a librarian. The number of books and loans increased, and two smart libraries in areas without public libraries showed high usage rates. Although users were satisfied with the smart libraries, they pointed out inconveniences such as the limited number of loan books and insufficient books. Consequently, it is suggested to improve user-centered service quality, continuous monitoring and evaluation, as well as active promotion.

Exercises using a Balance Board (BB) are effective in developing balance, strengthening core muscles, and improving physical fitness and concentration. In particular, the Smart Balance Board (SBB), which integrates with various digital content, provides appropriate feedback compared to traditional balance boards, maximizing the effectiveness of the exercise. However, most systems only offer visual and auditory feedback, failing to evaluate the impact on user engagement, interest, and the accuracy of exercise postures. This study proposes an Immersive Smart Balance Board (I-SBB) that utilizes multiple sensors to enable training with various feedback mechanisms and precise postures. The proposed system, based on Arduino, consists of a gyro sensor for measuring the board's posture, a communication module for wired/wireless communication, an infrared sensor to guide the user's foot placement, and a vibration motor for tactile feedback. The board's posture measurements are smoothly corrected using a Kalman Filter, and the multi-sensor data is processed in real-time using FreeRTOS. The proposed I-SBB is shown to be effective in enhancing user concentration and engagement, as well as generating interest, by integrating with diverse content.
