In this paper, we propose a visualization interface of characters’ activity for considering user’s intention for analysis of match in the “League of Legends” (LoL). Previous interface calculates characters’ activity based on three perspectives with constant weights and per minute time period during the match. Therefore, a user can not reflect his/her intention to analysis by controlling weights of perspectives and select time period during the match. In this paper, we extend the previous interface and allow user controlling weight of the perspectives and select time period during the match, show effectiveness of proposed interface.

In an era where serialization prevails across all media, particularly in digital formats, understanding how these repetitive patterns impact the consumption of popular and mass media is crucial. Final Fantasy stands as a massively popular and highly serialized game series. Thus, this study seeks to comprehend the seriality present within the Final Fantasy game series. It intends to achieve this by employing the categorization proposed by Denson and Jahn-Sudmann, Umberto Eco’s taxonomy of serial production. The research primarily centers on the internal workings of the games themselves, particularly the main series and the serialized features within and between installments in the series. Analyzing the repeated patterns in comparison to features that have changed from game-to-game show that initially, FF incorporates elements from a broader context, including fantasy literature, manga and anime, TTRPG, and CRPGs. However, it then modifies these elements based on its own preferences. In this process, FF develops its own encyclopedia or database. Consequently, when creating each new game, the series draws from this database, reusing some elements and altering others. Therefore, the common thread linking all the installments in the series is not a single character, game mechanic, or universe, but rather a database or the encyclopedia.

With increasing self-awareness among women due to their growing societal presence in China, there is a noticeable emphasis on empowering them in otome games. The trend of ”da nu zhu” (大女主), or Big heroine, prevalent in content targeting women, is also common in games, where their systems prioritize playability. This paper focuses on the game design of works submitted to the Chinese online platform Cheng Guang and examines the needs of Chinese female gamers. Compared with otome games in Japan and the US, it aims to illuminate the distinctive features of women's games in China, shaped by its unique social context.

During gameplay, players sometimes treat NPCs like friends, sometimes like tools. In this study, I attempted to qualitatively clarify players' recognitions towards NPCs in order to consider how NPCs would appear in players’ minds, which cause players to have a polarized perception of “person” and “stuff”. As a result of constructivist GTA based on video ethnography of live gameplay and semi-structured interviews, it has become clear that there are four recognition forms towards NPCs: as a person, as a Kyara, as a game character, and as a system. In this paper, I consider each of these four forms of recognition, unwind the connection of these, and depict the overall structure of the recognition.

Recently, active research and tool development around generative AI has led light on, so that automatic game map generation is the critical example. However, it is not easy to generate the creator's ideal map in terms of the structure of rooms and roads in unconditional game dungeon map generation. Therefore, we propose an algorithmic method to automatically generate game maps with a high degree of freedom in accordance with the user's idea of the situation, such as not only room layouts but also two types of scenes of natural objects and buildings.

In previous game development, when applying textures to such vast terrain, A technique called tiling has been used to lay out a single seamless texture like a tile. However, the wider the area on which tiling is applied, the more the repeating pattern becomes noticeable. Therefore, the goal of this research was to improve the repeating feel of patterns and the lines that are visible at a distance. We focused on a method called texture blending, which combines two textures to create a natural look. Then, blend the tiled surfaces using Perlin noise as a mask image to create the pattern of the two textures. By making it appear sparsely, the repetitive feel of the pattern was reduced. In addition, for distant views, the textures pasted on tiles are randomly rotated for each tile, eliminating texture boundaries that are noticeable in distant views. Made it difficult to see. These processes made it possible to improve the sense of repetition that had been a problem with the tiling method.

Destruction is one of the most commonly used expressions in interactive content such as video games, which require visual reality and computational efficiency to respond dynamically. Real-time destruction simulation can be divided into physics-based methods, which determine the shape of debris based on external forces applied to the object, and non-physics-based methods, which determine the shape of debris based on geometric patterns and artists. In practice, non-physics-based methods are often used. Although there are examples of physics-based methods used in video games, they cannot generate accurate cracks and debris because the generated debris shapes depend on the model boundaries. In this study, we propose a physics-based method that can generate more accurate cracks and debris. This method uses the finite element method, and the failure target is represented by a volume mesh. The principal stresses applied to each element are used to determine whether the element should fail or not, and if so, the element is split along the fracture surface to generate physically correct cracks and debris.

We propose a match review interface based on individual gunfight skills for team FPS games. To win a match, individual skills during gunfight are importance skills, however previous match review interfaces do not consider the skills. Therefore, we calculate the risk of gunfight based on three factors related to proficiency of individual skills: number of enemies, distance between the enemy and the crosshair, and combat time. Proposed interface visualizes these factors. We perform subject experiments and show the effectiveness of the proposed interface.

This presentation provides an overview of the current status of game exhibitions in Japan, identifies associated challenges, and examines prospects for future game exhibitions. Despite two decades having passed since the advent of game exhibitions, it is undeniable that they heavily rely on playable exhibits. While such exhibits have led to increased visitor numbers and experiences of “fun“ from being able to play games, as well as a sense of “nostalgia“ from being able to revisit old games, various challenges have also emerged. To address these challenges, the “Game Exhibition TEN“ and “Game Exhibition TEN II“ events were held. These two exhibitions showcased a new potential for game exhibitions by presenting “non-playable game exhibitions“ and serving as “game exhibitions that introduce game exhibitions.“ Furthermore, the exhibitions introduced at both events demonstrated a shift from game exhibitions primarily centered around playable exhibits and nostalgic experiences to exhibitions that explore the production and cultural backgrounds of games, as well as utilizing games as context. This shift is seen as contributing to the future expansion and potential of game exhibitions.

The purpose of this presentation is to clarify how regional differences occur in the relationship between gaming culture and society. This presentation will focus on Chiba and Ibaraki prefectures, which are adjacent to each other but have distinctive differences in the debate on deregulation of game centers. The presentation will attempt to investigate and analyze regional differences in the relationship between game culture and society, based on the differences in the environment surrounding game culture in the two prefectures and in the discussions of game culture in the legislatures of both prefectures. As a result, it is clear that the differences in the relationship between game culture and society in the two prefectures and the regional characteristics of the relationship are influenced by the work of individuals and the local environment that allows it, and that there are differences in the social and political stance of political parties in the two prefectures.

In 2021, the Metaverse was widely recognized by the market, but is now considered to be in a disillusionment period and is receiving less attention. The main reason may be that user needs have not been identified in an environment where demand is not guaranteed. This study presents the results, analysis, and discussion of a survey of user needs and the current state of the Metaverse, conducted through a questionnaire with a sample of 562 people who have visited the Metaverse. This suggested that the current state of the Metaverse is supported by games and Gamers, but that the level of satisfaction remains low when compared to existing games. In addition, based on the analysis results, it was noted that developing a space that takes advantage of the characteristics of the Metaverse and targets non-Gamers could be an active path for the Game-based Metaverse.

Existing research on automatic difficulty balancing tests for FPS using AI had problems with the accuracy of the balancing test because it could not properly capture difficulty variations due to differences in play styles. In the proposed method, multiple AI agents with specific play styles created by combining reinforcement learning and rule-based agents are introduced. Through verification, we show that it is capable of detecting difficulty changes between different play styles as well as human players.

In the treatment of cataracts, a procedure is used that replaces the natural lens with an intraocular lens. Among these, multifocal intraocular lenses have multiple focal points, which can improve the patient's quality of life. However, patients with multifocal intraocular lenses may experience issues with how they see lights in dark conditions, such as at night. These issues include the 'halo phenomenon,' where light seems to spread around a point and appear as a ring-shaped haze, the 'glare phenomenon,' where light appears dazzling or glaring, and the 'starburst phenomenon,' where radial lines of light seem to emanate from a point. Although these phenomena are well-known, they are observed subjectively by individuals with intraocular lenses, limiting objective discussion. We are advancing research to recreate these phenomena in a VR space through post-processing in 3D computer graphics. Ultimately, we aim to perform patient-specific post-processing that matches the halo, glare, and starburst phenomena each intraocular lens wearer experiences, in order to objectively assess these phenomena. This report discusses the post-processing capable of reproducing the halo, glare, and starburst phenomena, and considers the application of game-related technology in healthcare, specifically gamification and serious games.

In this study, we extend a field-of-view expansion method that visualizes 360° spherical information in the virtual space as circular and annular fisheye images based on equidistant projection using an HMD to efficiently discover objects and perform subsequent actions. We report the results of devising and implementing two functions that strengthen this purpose. The first function is to display auxiliary lines useful for specifying the positions of objects in the virtual space, and displays several great circles of a certain size around the user. The second function is to discover an object using the aforementioned fisheye image and then perform an action using the controller in that view. Here, we targeted shooting and confirmed that it was possible to discover objects and hit them using the view and the two proposed functions.

Science communication has gained importance in recent years. This generally refers to outreach activities to society in the natural sciences, but it may be equally important in the humanities. It has also been pointed out that there is a need for multi-layered communication that involves citizens more proactively, not only in the traditional way of promoting public understanding. This study focused on a gaming method to encourage engagement, and developed and practiced the escape room. The game was designed to encourage participants to think about the 'significance of foreign language learning in the modern age'.

This research aims to reduce the burden and improve the efficiency of game sound development, especially music production, and proposes a unique game sound production method called the “Map x Motif Model. This model links “motifs,“ which serve as a foothold for music production, with “ map information“ in the game. It is characterized by two points: “early creation and application of music element “motifs““ and “utilization of the field map concept of the game. Through the “SIG-AUDIO“ online seminar, the model was proposed to game sound production professionals and evaluated through a questionnaire. Based on the results of the evaluation, it was concluded that the “early creation of motifs“ of the model is effective, but that the “ utilization of map concepts“ is not worth the usefulness and man-hours required.

While the video game streaming market is rapidly growing, the time spent playing on game consoles and mobile games is decreasing. This trend suggests an increase in the number of people who watch gameplay videos rather than playing the games themselves. In this study, we created a custom 2D escape game for experimental purposes and investigated whether there is a difference in memory retention of the game's content between those who played the game and those who watched a gameplay video. We conducted memory tests on the game's content for both groups – those who played and those who watched – after playing or watching and compared the results. A comparison of the character count in free-response sections of memory-related surveys revealed that the watching group had significantly more characters than the playing group. Furthermore, the playing group showed a potential tendency to forget older information compared to the watching group. This study elucidates the differences in memory retention during gameplay and watching under the conditions of this study.

Though some cases of gamification practices in education in Japan have been reported, the number of cases in the higher education remains few compared to those in the primary and secondary education. In this paper, we consider the application of gamification in the Japanese higher education, and examine how rewards should be provided. Based on the results of preceding cases and the principle of self-determination theory, we designed remuneration that could be implanted at a Japanese university, and investigated its consistency with what students wanted. The questionnaire survey revealed that students want praise from those around them, quick feedback on their work, and information about their progress.

This paper discusses the three levels of output of historical research on games: 1) documents (archives), 2) monographs/case studies, and 3) period/departmental histories, and then discusses historical diversity from three perspectives: 1) diversity in the evaluation criteria held by the authors, 2) diversity in the subject matter under discussion, and 3) diversity in the development paths of different countries. The author also discusses historical diversity from three perspectives: 1) diversity according to the authors' evaluation criteria, 2) diversity according to the subject under discussion, and 3) diversity in the development path of each country. In addition, since the current game playing environment (platform) is converging in various countries around the world, genre history and game consumption culture theory concerning the rise and fall of game genres will become important in the future history of the game industry. Ultimately, the game industry history of each country may converge on one of two types in terms of artwork, ”Eastern” or ”Western,” with only slight differences due to differences in consumer culture.

It has been more than 20 years since engineering ethics began to be taught in academic universities, but it seems that engineering ethics is not fully functioning in some parts of the manufacturing industry, as evidenced by the fact that whistle-blowers and other means within the companies are still uncovering fraudulent inspection data. It has been 15 years since the author began teaching ethics for engineers to students studying information engineering, including game development, at universities, and in this course, I have tried to use AI and VR technologies, which are new information technologies, as examples as much as possible. However, although SNS has been used as an effective tool for marketing in the past, its use for digital influence through disinformation has become conspicuous. In addition, games have come to play a role in the transmission and diffusion of information, and the time has come for game developers to compile a set of ethics for engineers. In this paper, we explain the ethics for game developers based on our educational experience in ethics for engineers, and discuss the elements of engineer ethics that should be considered from the stage of game planning.

In the context of player self-expression and social interaction within games, attention is given to political or social activities. A case study is conducted on these activities and the responses of game developers to them. Following this, the necessary literacies for players and developers in the context of political or social activities within games are examined. It is argued that players need game literacy, which includes the ability to avoid discrimination, bullying, and harassment, and to play in accordance with the terms of service. Additionally, it is discussed that developers need game development literacy, which involves the ability to set criteria for restricting or prohibiting political or social activities within the game, and to make quick and strict decisions on ambiguous cases regarding restrictions or prohibitions.

I created ”Munenohi Voltage”, a romantic adventure game about a community in the e-sports industry. Although the e-sports industry has been developing at a dizzying pace in recent years, the people who are active in the industry, the systems being built, and the actual state of the community are hardly recognized by the general public. Therefore, we planned this work to make many people aware of the esports industry through the story. Focusing on the community of Nintendo's competitive action game ”Super Smash Bros ultimate”, we conducted interviews and research to analyze the industry's characteristics and current situation. Based on the scenario created based on that research, illustration design and game script were created to create a visual novel game. We also aimed to reach a wider audience by producing the game in the ”romance adventure” genre, which is extremely popular as a visual novel game.

In recent years, game engines such as Unity and Unreal Engine, which provide the functions, programs, and materials necessary to create games, have developed. With this development, an environment has been created in which anyone can easily develop games with high efficiency and quality. However, it is difficult to estimate the amount of work to be done and the time required for game production. Therefore, we are developing a system that enables developers with little development experience to grasp and visualize the production required in the planning and production stages. As a result of the evaluation experiment, significant differences were obtained in the ”creation time” and ”difficulty level” of the Gantt chart, which enables the understanding of necessary production items. In addition, good evaluations were also obtained for ”discovery of new development items,” ”comfort of use,” and ”content of questions in the development system.
