Today, Augmented Reality (AR), Virtual Reality (VR), and Mixed Reality (MR) technologies are becoming fundamental across a wide variety of application domains. All these technologies fall under the Extended Reality (XR) spectrum. Areas in which XR technologies and, in particular, immersive experiences have been successfully introduced are expanding daily, from traditional areas, such as entertainment and video game production, to novel scenarios, such as industry, healthcare, smart cities, and autonomous vehicles, to mention a few. The spread of XR and VR is also driven by technological advancements that are making new ways of operating within virtual experiences easier, and sometimes even possible. In particular, the availability of new hardware and software tools make the use of '3D reconstructions', 'digital twins' and 'simulations' commonplace in many XR and VR applications. For example, the possibility to leverage networks with higher bandwidth than never before and lower latency makes it possible to transmit the amount of data needed for massive, real-time digital twins, whereas high-performance hardware enables the reconstruction of high-fidelity digital objects and environments, while lowering the time needed for high-demanding simulations. The aim of the 3D Reconstruction, Digital Twinning, and Simulation for Virtual Experiences (ReDigiTS) workshop is to bring together researchers, practitioners, educators, and students to share ideas and promote further work in this growing area of 3D reconstruction, digital twinning, and simulation in VR and related technologies. © 2023 IEEE.

Foodbot Factory is a serious game for nutrition education geared to children in grades 4–6. Foodbot Factory was developed by an interdisciplinary team of university researchers and students spanning various expertise including Computer Sci-ence/game development, Health Sciences/Nutrition, and Education, with limited funding leading to various challenges through-out the development process. We believe that our development experience will be of use to other serious game developers. In this paper, we provide recommendations to researchers, designers, and developers of serious games (including students), particularly those with limited resources, common in university research labs where the majority of serious games design and development takes place.

The study examines the research–practice partnership (RPP) model aimed at co-constructing and integrating computational thinking (CT) in culturally responsive (CR) ways within early childhood and elementary (PreK-5) classrooms, focusing on teachers' RPP experiences. Recent research underlines the importance of integrating CT in early childhood and elementary education, demonstrating that culturally, linguistically, and developmentally responsive computational activities in PreK-5 settings are key to such efforts. However, there is a gap in research regarding effective professional development models that would prepare early childhood teachers in terms of both disciplinary ideas and practices of CT, as well as attending to cultural, linguistic, and developmental differences in young children in asset-based ways. Our research contributes to this body of knowledge by examining how RPP can be a model for teacher learning in which teachers, administrators, and researchers can co-develop knowledge and confidence in integrating CT into the PreK-5 teaching curriculum and practices in CR ways. The study outlines the collaborative development of processes and frameworks co-constructed by the RPP educators, as well as teacher-developed curricular materials and lesson plans integrating CT in CR ways. Findings include teachers' experience of these lessons and teacher insights about the support needed to incorporate CT and CR practices into their existing curricula. The study concludes by highlighting the potential challenges and opportunities inherent in such endeavors, thereby contributing to the broader discourse on supporting CT integration into early childhood classrooms in CR ways.

The practice of building intelligent narrative technologies is implicitly grounded in a sociopolitical context whose values are reflected in the artifacts we build and our narration of their use. This position paper attempts to make these implicit values explicit by naming them and conceptualizing alternatives. We argue for adopting a Critical Technical Practice of narrative intelligence in which explicit critical reflection on the values and metaphors a system's assumptions embed is interwoven into the design process. We demonstrate a broad application of this practice by identifying four ideals underlying narrative intelligence systems that impose and reflect systems of power: the Hero's Journey, Amalgamated Human Authorship, Social Believability, and the Holodeck. We then identify values that are marginalized by these ideals, such as narrative pluralism, amplifying underrepresented voices, representation of non-normative identities and relationships, and opportunities for reflection and interpretation. Finally, we propose imagined alternatives to existing ideals that bring these marginalized values to the center. © 2020 for this paper by its authors.

Application of Mobile Augmented Reality (AR) as a learning solution in innovation facing the education era 5.0. for vocational students on the computer network device topic, we promote in this paper. The purpose of this study is to apply AR technology-based applications by maximizing all of its interactions in the learning process about computer network devices so that students can know and understand their functions, then conduct an assessment of User Interface (UI) and User Experience (UX). The detection approach uses a marker-based tracking method, by bringing up 3D objects, rotating and touching, information and tool functions in the form of text, and producing sounds as information clues. A total of 30 students from one of the vocational high schools have been involved to use this application. After being analyzed for the current situation the students were very enthusiastic in following the learning process, then in the analysis of student understanding results obtained an average value of N-Gain was 67.41 which was proven that AR application could improve learning effectiveness, the results of the UI assessment with a value of 98.70% have a very strongly agree predicate to the application interface has been met, and the results of the assessment of the experience of users with a value of 98.94% have a very strongly agree predicate to the experience of using the application has been fulfilled.

Networks and local systems add delays to user actions in computer games, increasing the time between user input and rendering on the screen. Top-down studies using games have helped understand the impact of delays, but often do not generalize nor lend themselves to analytic modeling. Bottom-up studies isolating user input can better generalize and be used in models, but have yet to be applied to computer games. Our work builds a custom game for studying delay and the fundamental user input of selecting a moving target with a mouse. Analysis of data from a large user study shows target selection time is exponential with delay, and provides for an analytic model based on delay and the interaction between delay and target speed.

The degradation of player performance in network games with latency is well documented. However, quantifying the effects of latency on player individual actions is an unmet challenge. Under constrained bitrate conditions, player actions delayed on the client add additional latency, so network game developers need tools to help prioritize the sending of player actions. This paper presents a taxonomy for player actions with latency in network games, where player actions are defined by their precision, dead-line & impact. The effects of latency along each dimension of the taxonomy are analyzed through extensive experiments with a custom 2d game. Efficacy of the taxonomy in game development is illustrated by experiments that show improved player performance when prioritizing player actions based on their expected impact derived from the taxonomy dimensions.

IEEE games media Entertainment (GEM)

作者： Meng Luo Mark Claypool Computer Science and Interactive Media & Game Development Worcester Polytechnic Institute Worcester MA USA

Cloud gaming is an emerging service based on cloud computing technology which allows games to be run on a server and streamed as video to players on a lightweight client. Commercial cloud gaming systems, such as Playstation Now and StreamMygame remain proprietary, limiting access for game developers and researchers. In order to address this shortcoming, we present an open source cloud-based game system prototype in Unity called Uniquitous that gives game developers and researchers control over both the cloud system and the game content. Detailed experiments evaluate the performance of Uniquitous for two main parameters, game resolution and game image quality, using two different games. The evaluation results are used in a data model that can predict in-game frame rates for systems with configurations beyond those tested. Validation experiments show the accuracy of our model and complement the release of Uniquitous as a potential research and development platform.

Annual Workshop on Network and Systems Support for games (Netgames)

作者： Mark Claypool David Finkel Computer Science and Interactive Media & Game Development Worcester Polytechnic Institute Worcester MA USA

Cloud-based games are an increasingly popular method to distribute and play computer games on the Internet. While there has been some work studying network aspects of cloud-based games and examining the effects of latency on traditional games, there has not been sufficient research on the impact of latency on cloud-based games nor a comparison of the impact of latency on cloud-based games versus traditional games. This paper presents the results of two user studies that measure the objective and subjective effects of latency on cloud-based games, one study using the commercial cloud game system OnLive and the other study using the academic cloud game system GamingAnywhere. Analysis of the results shows both quality of experience and user performance degrade linearly with an increase in latency. More significantly, latency affects cloud-based games in a manner most similar to that of traditional first-person avatar games, the most sensitive class of games, despite the fact that the cloud-based games may have a different user perspective. These results have implications for cloud-based game designers and cloud system developers.

The growth in network bitrates and server-based processing has provided a renewed opportunity for thin client games, where the server does heavy-weight computations, sending only the visual game frames to the client, and the client displays frames, sending only the user actions to the server. Understanding the traffic characteristics of thin client games is important for building traffic models and classifiers and planning network infrastructures to meet future demand. This paper provides the first detailed study of the network characteristics of OnLive, a commercially available thin client game system. Carefully designed experiments measure OnLive game traffic for several game genres, analyzing the bitrates, packet sizes and inter-packet times for both upstream and downstream game traffic, with comparisons to traditional game clients and streaming video. Results indicate OnLive rapidly sends large packets downstream, similar but still significantly different than live video. OnLive less frequently sends much smaller packets upstream, significantly different than traditional game client traffic. The results should be a useful beginning for building effective traffic models and classifiers, and for preparing end-host networks to support this upcoming generation of computer games.
