    The Metaverse offers a second world beyond reality, where boundaries are non-existent, and possibilities are endless through engagement and immersive experiences using the virtual reality (VR) technology. Many disciplines can benefit from the advancement of the Metaverse when accurately developed, including the fields of technology, gaming, education, art, and culture. Nevertheless, developing the Metaverse environment to its full potential is an ambiguous task that needs proper guidance and directions. Existing surveys on the Metaverse focus only on a specific aspect and discipline of the Metaverse and lack a holistic view of the entire process. To this end, a more holistic, multi-disciplinary, in-depth, and academic and industry-oriented review is required to provide a thorough study of the Metaverse development pipeline. To address these issues, we present in this survey a novel multi-layered pipeline ecosystem composed of (1) the Metaverse computing, networking, communications and hardware infrastructure, (2) environment digitization, and (3) user interactions. For every layer, we discuss the components that detail the steps of its development. Also, for each of these components, we examine the impact of a set of enabling technologies and empowering domains (e.g., Artificial Intelligence, Security & Privacy, Blockchain, Business, Ethics, and Social) on its advancement. In addition, we explain the importance of these technologies to support decentralization, interoperability, user experiences, interactions, and monetization. Our presented study highlights the existing challenges for each component, followed by research directions and potential solutions. To the best of our knowledge, this survey is the most comprehensive and allows users, scholars, and entrepreneurs to get an in-depth understanding of the Metaverse ecosystem to find their opportunities and potentials for contribution

    OpenAI has recently released GPT-4 (a.k.a. ChatGPT plus), which is demonstrated to be one small step for generative AI (GAI), but one giant leap for artificial general intelligence (AGI). Since its official release in November 2022, ChatGPT has quickly attracted numerous users with extensive media coverage. Such unprecedented attention has also motivated numerous researchers to investigate ChatGPT from various aspects. According to Google scholar, there are more than 500 articles with ChatGPT in their titles or mentioning it in their abstracts. Considering this, a review is urgently needed, and our work fills this gap. Overall, this work is the first to survey ChatGPT with a comprehensive review of its underlying technology, applications, and challenges. Moreover, we present an outlook on how ChatGPT might evolve to realize general-purpose AIGC (a.k.a. AI-generated content), which will be a significant milestone for the development of AGI.Comment: A Survey on ChatGPT and GPT-4, 29 pages. Feedback is appreciated ([email protected]

    Bounding Box Annotation with Visible Status

    Full text link
    Training deep-learning-based vision systems requires the manual annotation of a significant amount of data to optimize several parameters of the deep convolutional neural networks. Such manual annotation is highly time-consuming and labor-intensive. To reduce this burden, a previous study presented a fully automated annotation approach that does not require any manual intervention. The proposed method associates a visual marker with an object and captures it in the same image. However, because the previous method relied on moving the object within the capturing range using a fixed-point camera, the collected image dataset was limited in terms of capturing viewpoints. To overcome this limitation, this study presents a mobile application-based free-viewpoint image-capturing method. With the proposed application, users can collect multi-view image datasets automatically that are annotated with bounding boxes by moving the camera. However, capturing images through human involvement is laborious and monotonous. Therefore, we propose gamified application features to track the progress of the collection status. Our experiments demonstrated that using the gamified mobile application for bounding box annotation, with visible collection progress status, can motivate users to collect multi-view object image datasets with less mental workload and time pressure in an enjoyable manner, leading to increased engagement.Comment: 10 pages, 16 figure

    The flipped classroom approach has gained significant popularity recently due to its ability to facilitate active learning and leverage technology to enhance student's learning habits. Previous research has explored the benefits and drawbacks of this approach, highlighting its potential to improve student engagement, motivation, and achievement. However, despite the growing interest in flipped classroom approach, more is needed to know about teachers' perceptions of this model and how these perceptions may vary based on years of experience.The current study aims to address this gap in the literature by examining 73 Kindergarten through 12th-grade teachers' perceptions of flipped classroom approach and identifying differences in these perceptions based on years of experience. To this end, the study utilized a survey instrument developed by Gough et al. (2017) to gather data on teachers' attitudes toward flipped classroom approach across five domains, including instructional practices, student considerations, technology use, communication, and practice.By analyzing the survey data, the study identified significant differences in teachers' perceptions of flipped classroom approach based on years of experience. Specifically, teachers with 0-3, 3-5, and more than 5 years of teaching experience had different judgments in instructional practices and student considerations. These findings suggest that teachers' perceptions of flipped classroom approach may be influenced by their experience level and that targeted professional development and training may be necessary to support teachers in adopting this approach effectively.Overall, this study contributes to the literature on flipped classroom approach by shedding light on teachers' perceptions of this model and how these perceptions vary based on years of experience. The findings provide insights into the elements that could enhance the effectiveness of flipped classroom approach, such as differentiation, more videos for specific learners, communication with all parties, and practice. The practical implications of these findings for K12 settings are discussed in the subsequent sections of this article.

    Urban supply networks are facing increasing demands and challenges and thus constitute a relevant field for research and practical development. Supply chain management holds enormous potential and relevance for society and everyday life as the flow of goods and information are important economic functions. Being a heterogeneous field, the literature base of supply chain management research is difficult to manage and navigate. Disruptive digital technologies and the implementation of cross-network information analysis and sharing drive the need for new organisational and technological approaches. Practical issues are manifold and include mega trends such as digital transformation, urbanisation, and environmental awareness. A promising approach to solving these problems is the realisation of smart and collaborative supply networks. The growth of artificial intelligence applications in recent years has led to a wide range of applications in a variety of domains. However, the potential of artificial intelligence utilisation in supply chain management has not yet been fully exploited. Similarly, value creation increasingly takes place in networked value creation cycles that have become continuously more collaborative, complex, and dynamic as interactions in business processes involving information technologies have become more intense. Following a design science research approach this cumulative thesis comprises the development and discussion of four artefacts for the analysis and advancement of smart and collaborative urban supply networks. This thesis aims to highlight the potential of artificial intelligence-based supply networks, to advance data-driven inter-organisational collaboration, and to improve last mile supply network sustainability. Based on thorough machine learning and systematic literature reviews, reference and system dynamics modelling, simulation, and qualitative empirical research, the artefacts provide a valuable contribution to research and practice

    Get PDF
    Today’s teachers are being encouraged to incorporate technology into their classrooms. Technology integration became a worldwide focus for schools after remote learning was necessary to continue instruction due to the COVID-19 pandemic. Additionally, research shows that technology-infused lessons improve student achievement and increase student engagement. Despite efforts to support teachers throughout the technology integration process, concerns have developed. Preparing highly qualified teachers ready to incorporate technology into their teaching repertoire has developed additional stress factors. In this descriptive qualitative study, the researcher wanted to address the problem of teacher attrition, possibly related to stress factors associated with technology integration. The purpose of this qualitative descriptive study was to explore teachers’ perceptions of professional development opportunities that possibly improve the technology integration process. Additionally, the researcher wanted to identify stress factors associated with technology adoption and how professional development may help to reduce stress factors associated with technology integration in one middle school in New York. The researcher chose a qualitative descriptive study using Vygotsky’s social constructivist theory and Bandura’s social learning theory on self-efficacy as the theoretical framework. The researcher included an exposition of the literature sources, synthesized the research findings, and provided recommendations for practice and future research. The data collection process consisted of semistructured open-ended questions that were developed with the support of a panel of experts. There were 10 participants chosen using a snowball sampling strategy. This study’s findings were that professional development should be hands-on, continuous, and targeted to increase teachers’ personal level of engagement. Also, creating opportunities for colleague support systems reduced stress factors associated with technology integration. These peer support systems reduced the time required to research the most effective resources, digital tools, and applications as participants shared the resources with one another. Recommendations for practice included providing adequate professional development, offering appropriate infrastructure, and hands-on, targeted, continuous training for teachers to feel more comfortable developing technology-infused lessons. Recommendations for research include providing additional insight into teachers’ perceived benefits and motivation for technology integration and how stress factors associated with the technology adoption process possibly increase teacher attrition

    Redefining quality interpersonal communication and communication activities in marriage from divorcees’ perspectives

    Get PDF
    Quality interpersonal communication is essential in the development and maintenance of any relationship, including marriage. As society adapts to new avenues of communication, married couples often underestimate the relevance of interpersonal communication in their relationship due to their lack of understanding of quality interpersonal communication. Therefore, this study investigated the conceptualisation of quality interpersonal communication through the lens of Relational Dialectic Theory and communication activities in marriage from the perspectives of divorcees. This study also explored the antecedents of poor-quality interpersonal communication and its repercussions on married couples. The present study also extended Knapp’s Relational Development Model by incorporating communication technology as a medium of communication. In-depth interviews were conducted on 20 divorcees from different states in Malaysia, chosen through a purposive sampling technique. The gathered data was then evaluated and combined in a thematic data analysis using the NVivo 12 software. This study discovers that the definitions of quality interpersonal communication are divided into seven (7) categories, with communication skills, intimacy, and characters identified as the top three significant traits. Results of this study also indicate that spouses use various medium of communication based on their circumstances but prefer face-to-face communication. However, communication occurrences between spouses are low and mostly negative, with the majority of them mainly involving households and children. The other antecedents of poor-quality interpersonal communication are communication skills, attitudes, third-party involvement, and emotional condition. The current study concludes that emotional condition is one of the protuberant effects of poor-quality interpersonal communication. All in all, the current study provides a new paradigm in Knapp’s Relational Development Model through the incorporation of the effects of poor-quality interpersonal communication into the deterioration stages of the model
