In recent years, there are many game genres called open world racing games. In this game genre, it is a racing game with the feature that you can explore a vast map and race and time attack in various places. In this game genre, there are general vehicles that run according to the traffic rules in the game. The traffic flow formed by general vehicles is different from the traffic flow formed by automobiles in the real world, and there is no difference in traffic flow between developed cities and rural towns. There is a problem that the traffic flow does not change according to the change of the map environment, so it cannot play a role as a part of the landscape. Also, by assuming multiplayer, it is difficult to make adjustments by simply adding or deleting general vehicles because there are multiple players’ fields of vision. Therefore, In this research, we aim to propose a traffic flow adjustment method for general vehicles considering the visibility of multiple players.

A route graph is used for route search in the game field, but the more routes there are, the longer the calculation time. For this reason, a method of obtaining the degree of importance, which serves as an index for reducing routes, has been proposed. However, when route graphs are generated in real time, it is important to shorten the calculation time of the route importance calculation method. In this research, we proposed and verified a method to quickly calculate the importance of a route from the length of the shortest route between vertices around the deleted route. When the proposed method is applied to multiple route graphs, it is possible to shorten the computation time and obtain the degree of importance close to that of the previous method for some route graphs.

In this study, we analyzed the features for judging whether a player understands the program he/she is typing based on keystroke information such as typed keys and their times in a program typing game. The results showed that (1) the average typing speed during a typing game can be used to separate the understanding from the non-understanding with about 70% accuracy, (2) a machine learning model using the relative interval time normalized from 0 to 1 for each individual can be used to classify with about 80% accuracy, and (3) the features that machine learning discovered were that people who understand the program type line breaks relatively slower than other keys. We further analyzed whether these characteristics appeared as understanding of the program increased, or whether they were inherent characteristics of the user, and found that they appeared from the beginning of the program class. We can infer that some kind of programming background influences the keystrokes.

Real-time rendering of human skin is difficult because of the huge computational effort required to simulate the sub-surface scattering phenomena that occur inside the object. In order to increase rendering efficiency, many games ignore the transmitted light effect of the skin. Based on the Pre-Integrated Skin Shading method, the angle between the light and the normal and the skin thickness are used as parameters, and the transmitted light effect from the depth map-based Pre-Integrated can be saved in an LUT to read the color values in a look-up table and used as transmitted luminance in the lighting calculation. This improves the calculation speed.

Game developers are focusing their efforts on developing environments for game worlds to provide users with a high degree of realism. However, creating high-quality models necessitates the production of equally high-quality textures, which can be cost-intensive and laborious. In response to this challenge, we propose a method for automatically generating high-quality 3D model textures using deep learning in this study.

Body regeneration, the ability to rapidly heal themselves from an injury, is commonly depicted in video game contents. However, the visual expression of this phenomenon lacks in terms of mesh deformations due to the technical limitations inherent in the video game contents. We present a new method for a body regeneration effect utilizing pre- computed morph target shapes that can dynamically be connected at run time to define the shape of the injury. By changing the connectivity of deformation shapes at the runtime, our method can depict an injury and its regeneration with topological alterations, from an arbitrary body location.

This study explores the issue of misogyny in digital gaming culture through interviews with Chinese female gamers. It shows that for female gamers, gaming culture is exclusive and male-dominated. It became clear that there is a contradiction between the identities of being a woman and a gamer. Furthermore, although female gamers have taken various strategies to combat misogyny in gaming culture, their strategies are limited in overturning the underlying structure of discrimination.

While there are times when players see NPC as very close friends, there are also times when treating them as mere objects in a game system. This study tries to depict how real these fictional NPCs would appear in players’ minds depending on changes in players’ recognition towards NPCs. Regard to the study method, I analyzed the players’ utterance while their playing games by using Constructivist GTA and drew a structural map that shows how their recognitions change. As a result, I have found out 4 core categories, consisting of 3 recognition forms "as person", "as character", "as system" and 1 affecting element "natural or unnatural". I also knew that an image of NPC, such as "image as person", "image as character", "image as system" was built up in each recognition form. This is an interim report of my master degree study which is still under examination and analysis. I intend to enrich the content with more data and accomplish this study.

In this paper, we prototype a visualization system of characters’ activity for considering user’s intention for analysis of match in the "League of Legends" (LoL). Previous system calculates characters’ activity based on three attributes 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 attributes and select time period during the match. In this paper, we extend the previous system and allow user controlling weight of the attributes and select time period during the match.

With the proliferation of digital games, analog games have been digitally transplanted. This study conducted a quantitative survey regarding this digitalization. The results showed that most gaming opportunities are now with digital games. This is due to the convenience of being able to play them casually and the benefits of online competition. On the other hand, analog games are valued for their face-to-face interactions that extend beyond the game itself and for the experience of playing with physical objects.

This presentation highlights the inadequate enforcement of online gambling regulations in China's esports industry. Despite established guidelines, there is a lack of criminal or administrative penalties for online gambling related to esports, as demonstrated through three examples: esports teams accepting sponsorships from gambling companies, no punishment for players involved in match-fixing, and failure to prosecute an esports tycoon running a gambling house. The article suggests that cultural reframing strategies and the significant impact of esports on China's politics and economy might contribute to this lack of enforcement. Implications of unregulated online gambling in the Chinese esports industry are underscored.

This presentation examines how e-sports, which is currently the focus of much attention, has taken shape over the years, comparing it to gaming competitions prior to the 2000's.This is because, in researching game magazines and other media at the time, it became clear that the structure, rules, and format of e-sports tournaments and matches were similar to those of fighting game tournaments using facilities such as the Kokugikan and Makuhari Messe.In addition to the large-scale video game competitions mentioned above, small-scale video game events were held in video game arcades and game stores at the time, and the applicant believes that some of the elements of these events were also incorporated into e-sports. However, looking through the previous studies related to e-sports, we do not see many studies that focus on the transition from video game competitions to e-sports, but rather studies that refer to the economic effects of e-sports, legal issues, and so on.Therefore, I believe that conducting a historical transition of video game competitions and e-sports in Japan from the perspective of media studies and cultural history research is very significant due to its rarity. In my presentation, I will mention the differences and common problems, referring to materials of game magazines and industry journals at the time as necessary, and mention what lessons need to be learned from the past cases for the development of e-sports.

The nexus between game-play and learning, as well as adaptation, has been a recurrent theme in scholarly discourses. This relationship is not solely a product of contemporary discourses but can be traced back to antiquity. Beginning with Plato's seminal work, "The Laws," progressing to Grose's theory of preparation, the theory of optimal arousal , theories of motivation, principles of developmental psychology, and the chunking hypothesis, the conceptualization of play-game theory has evolved in tandem with various tenets of cognitive science and psychological learning theories. This paper tries to provide a succinct overview and categorization of salient theories and arguments chronicling the trajectory of this discourse, from its ancient inception to contemporary debates.

In this paper, we propose an interpretable real-time win prediction model in fighting games. Previous studies about match of the win prediction in e-Sports have focused on MOBA, primarily using a method that defines the progress of the game based on time. However, this method may not always be optimal for fighting games due to variability in round durations. Therefore, we propose a model that defines the progress of the game based on health instead of time, and show its effectiveness.

Chat through keyboard input and voice chat are generally used in online games as a communication tool among players. However, there are issues such as the time required for input and being nervous about speaking up. This paper proposes a text-chat system by using speech recognition. The proposed system is expected to improve the qualities of communication and gaming experience through the online games. This study attempted to verify the accuracy of speech recognition and smoothness of communication by having subjects experience a prototyped game. Unity was used for the game prototyping, and Julius was used for the speech recognition system. As a result, the recognition rate was 23.1%. Improvement of the speech recognition accuracy is required for future issues.

In this paper, we propose a method for calculating the degree of danger during shooting combat in the FPS game “Valorant.” The game is a 5vs5 team fight game, and player’s skills of shooting combat are important factors for winning the game. However, previous game analysis can not measure the degree of danger during combat in which the player’s skills of shooting combat are important. Therefore, this paper investigates a method for calculating the degree of danger during shooting combat by focusing on the player’s skills of shooters, such as Pre-Aim and Peek.

We propose a one-way coupling framework between the water surface and rigid to simulate a does not exist phenomenon in which the energy wave passes through the surface of the water and causes ripples. In this framework, the aim of this specific model, compared to the general simulation method, is to combine rendering technical like ray tracing and space clipping to decrease the computational load. We also offer user- defined parameters to model interactions between the energy wave and the water surface.

Current input interfaces for games are designed mainly for able-bodied people, and the needs of physically challenged people are not fully considered. In this study, we attempted to develop a new input interface using respiration which is a natural action for everyone. However, conventional methods of measuring respiration are less comfortable and not suitable for prolonged use. Therefore, we created a command input to the game based on respiration estimated from the electrocardiogram (ECG). The results suggest that the respiration estimated from the ECG might be used as an input to the game.

Cataract treatments often involve replacing the lens with an intraocular lens. In particular, multifocal intraocular lenses, which offer multiple points of focus, can potentially improve patients' quality of life. However, patients with multifocal intraocular lenses may experience visual disturbances in low light conditions, such as at night, referred to as the halo and glare phenomena. Specifically, these include the 'halo phenomenon,' where light seems to spread around a point of light, giving the appearance of a ring-shaped haze, and the 'glare phenomenon,' where light appears to flicker or be excessively bright. These phenomena are well-known but are typically observed through the subjective vision of intraocular lens wearers, limiting objective discussions. Our research is advancing towards the reproduction of these phenomena in a virtual reality (VR) environment using post- processing in 3D computer graphics (3DCG). Ultimately, our goal is to individually customize the post-processing to match the halo and glare phenomena experienced by each intraocular lens wearer. Through this, we aim to establish an objective evaluation of the halo and glare phenomena. In this paper, as the first step of our research, we report on post-processing that can successfully reproduce the halo and glare phenomena.

As digital games become a media platform and e-Sport events become more popular, it is important for event creators and sound engineers to understand the listening experience in online entertainment spaces. In this paper, we report on the results obtained through system construction and demonstration experiments, as well as future issues, regarding a method for appropriately monitoring the acoustic space from the standpoint of an event creator by setting up a fictitious event space in the metaverse space. Assuming that a metaverse venue would be set up in the cluster using Unity, multi-channel audio input/output was realized by receiving and transmitting UDP packets using Max8. In order to achieve both the liveliness of the entire metaverse venue and to improve the intelligibility of the audio when visitors enter the booths they are interested in, we designed our own distance attenuation curve that is in line with the performance of the event, instead of using physical distance attenuation.

Educational gamification has become increasingly popular in recent years. Its goal is to change people's thinking and behavior in a variety of areas, including health, work, and media. On the other hand, gamification to actually promote behavioral change in response to social issues (hereafter referred to as " gamification for addressing social issues ") also exists but is said to be under-researched. The aim of this study is to identify the requirements for implementing for social implementation of gamification for addressing social issues. Through the development and experimentation of "Poker Rally on Smartphones," it was discovered that it is not necessary to create a game from scratch, as utilizing existing game rules alone can still lead to expected behavioral changes.

This study, recognizing the game-based structures present in school education, models a 'multi-game structure' in which multiple games are simultaneously being played within the school, and examines its application to specific matters. In the context of preceding research related to the multi-game structure, I reviewed discussions in evolutionary game theory, works by Carse, Suits, Noya, and debates in anthropology. I then illustrated the general form of the multi-game structure, where games with unlimited time and space progress, and games with limited time and space intermittently proceed. Within these games, there may be incompatible elements, or what appears to be the same game may in fact be different games. I discussed instances where the multi-game structure in school education can become problematic. I also discussed cases where different games are played between teachers and students, and incompatible games are played concurrently among teachers.

In recent years, museums and art galleries have increasingly held exhibitions focused on games. In these exhibitions, alongside original materials such as game software packages and media, there is often a display of playable gaming consoles to allow visitors to experience the games firsthand. However, playable exhibits come with the risk of wear and operational malfunctions due to user interaction. To maintain operability, repairs and maintenance may be necessary as needed. To ensure the transfer of game-related materials to the next generation, what preservation methods are essential, and what challenges lie ahead? In this session, the presenters will discuss the current state of game material preservation they have researched, share case studies from overseas game-specialized museums and the JAPAN GAME MUSEUM, and foster a discussion on these topics.

This paper has three aims. First, the importance of intrinsic motivation is illustrated using the Self- determination theory framework. Second, the theoretical relationships between video games and intrinsic motivation are explained. Specifically, intrinsic motivation can be enhanced by satisfaction of the basic psychological needs of competence, autonomy, and relatedness, through the provision of structured environment, the provision of meaningful choices and personalization opportunities, and the provision of opportunities for cooperation to experience connectedness. Thirdly, the future challenge for gamification is discussed. That is how to use the theoretical framework of motivation.

In multiplayer gameplay, communication occurs among players. This has been exploited in game design, where games are used as a communication tool. We investigated the occurrence and changes in player communication during games. The research was conducted in an implemented cooperative game, and we observed changes in communication by making rule changes to the initial prototype. At the result, the communication became more active with the inclusion of a rule proposing consultation. And by consulting before playing, the rules were better understood, and the game flowed better. In addition, winning as expected gave a sense of achievement and they became less attached to the game.

Video Game Music (VGM) is one of the most critical elements of a game. Selecting appropriate VGM is required to improve the quality of the game. Creators need to consider the differences in VGM for each scene (opening, dungeon, etc.). However, it is difficult for creators with limited resources to prepare as much appropriate VGM as necessary. Therefore, this paper proposes a system that retrieves appropriate VGM based on the game scenes created by creators and the games they referred to when creating their games. This paper first describes the system we have proposed in the past. This system retrieves VGM by predicting the audio features of the VGM from the video images of the game created by the creators. Next, we describe the problems of the previous system. Finally, we describe the newly proposed system. This system retrieves VGM by adapting the VGM of a game that the creators referred to when creating it to another scene.

This study focused on the Dualistic Model of Passion to examine the causal mechanisms of video games and well-being. We specifically examined the role of the intensity of passion for games as a possible mediator in this relationship. As a result, harmonic passion, obsessive passion, and time spent playing video games were not statistically significant mediating effects as mediating variables. These findings highlight the complex and subtle nature of mediation relationships and underscore the need for further investigation and model refinement to uncover potential mechanisms driving the observed effects.

The video game live streaming market has been experiencing rapid growth, while the playtime on gaming consoles and mobile games has been decreasing. This trend suggests an increase in the audience that prefers watching gameplay videos rather than playing video games themselves. In this study, we aim to investigate the differences in memory retention of game content between individuals who actively play a game and those who passively watch a gameplay video. To achieve this, we have developed a unique game for the experiment. A memory test relating to the game content is administered to two groups of participants - those who played the game and those who observed the gameplay video. The test takes place after each respective interaction with the game content. While this research is ongoing, we will present both the prototype of our experimental game and the process by which we have formulated the memory testing method.

Video games are one of the entertainments that contribute to improving quality of life. However, video games are difficult for people with visual impairments to play because most of the information comes only through sight. We have analyzed the difficulty of playing video games and considered the importance of audio feedback. As a result, we found that it is necessary to consider the design of "Player's selection on the menu screen" and "Player's movement in a 3D space to get around" in order to improve the quality of information accessibility. In this research presentation, we will demonstrate a prototype of a video game that was created from these two standpoints.

In such a modern society, there is a need for otaku people who are noted for "creating new value through creative expression" and "actively sending information to the community." This study focused on the "otaku power" possessed by such otaku people and examined the factors and structure of otaku power in academic situations. It was conducted that a questionnaire survey of students at two universities in the Tokyo metropolitan area. As a result, more respondents had a higher degree of otaku than a lower. There were more respondents with low otaku power than those with high. Regarding the use of otaku power in academic studies, respondents were more likely to answer questions about "ability to concentrate" and "knowledge gained from hobbies."
