This systematic literature review explores the utilization of narratives and digital games in this context, focusing on identifying the most common ludic and narrative immersion features employed in studies dedicated to animal phobias. Via a search on the Scopus and Web of Science scientific databases, twenty-nine studies were selected for in-depth analysis. The primary objective was to evaluate the presence of ludic and narrative elements in each study to understand their immersive potential across both dimensions. Findings suggest that ludic elements are more commonly used than narrative elements, which are notably scarce, and the exploration of the emotional dimension of narrative immersion is limited. An essential takeaway is that features fostering narrative immersion are invariably linked to the ludic dimension, often functioning as secondary components. This study provides a guiding framework for developing therapeutic interventions in VR, emphasizing the incorporation of ludic and narrative aspects. Additionally, it identifies untapped research opportunities, particularly the integration of autonomous narratives that are less reliant on ludic elements.","PeriodicalId":50645,"journal":{"name":"Computer Animation and Virtual Worlds","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135591058","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent studies have highlighted the effectiveness of graph convolutional network (GCN) based methods in this task, leading to a remarkable improvement in prediction accuracy. However, most GCN-based methods overlook the varying contributions of self, centripetal and centrifugal subsets. Besides, only a single-scale temporal feature is adopted, and the multi-temporal scale information is ignored. To this end, firstly, in order to differentiate the importance of different skeleton subsets, we develop a refinement graph convolution, which can adaptively learn a weight for each subset feature. Secondly, a multi-temporal scale aggregation module is proposed to extract more discriminative temporal dynamic information. Furthermore, a multi-temporal scale aggregation refinement graph convolutional network (MTSA-RGCN) is proposed, and four-stream structure is also adopted in this paper, which can comprehensively model complementary features and eventually achieves a significant performance boost. In the empirical experiments, the performance of our approach has been greatly improved on both NTU-RGB+D 60 and NTU-RGB+D 120 datasets, compared to other state-of-the-art methods.","PeriodicalId":50645,"journal":{"name":"Computer Animation and Virtual Worlds","volume":"35 1","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135770021","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, online classes often face challenges such as limited interactivity and display options, which can affect the quality and effectiveness of the online learning experience. In this article, we propose GestureTeach, a new pedagogical paradigm that enables free handwriting interaction and animation generation for online teaching. GestureTeach uses gestures as a natural and intuitive way of interaction, which enhances the teacher's intention expression and the student's engagement. GestureTeach also generates animations from handwritten sketches, which improves the display effects of the interaction and the student's knowledge comprehension. We conducted a two-stage study with 15 teachers and 90 students to evaluate the effectiveness of GestureTeach in facilitating classroom interaction. The results show that GestureTeach is preferred by both teachers and students over traditional online teaching methods and has the potential to transform the online teaching landscape by providing a seamless and interactive experience.","PeriodicalId":50645,"journal":{"name":"Computer Animation and Virtual Worlds","volume":"35 1","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135063534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it is not always feasible to take a large class on field trips due to time, safety, and cost limitations. To adequately prepare future professionals in the AEC industry, it is imperative that institutions adopt innovative methods of providing the field trip experience. One such approach is using virtual reality (VR) technology. Creating 3D VR construction environments and immersing students in that virtual world could provide an engaging and meaningful experience. Although researchers in AEC schools have developed and deployed many virtual field trips (VFTs) in education, little is known about their potential to provide the same knowledge base. For that reason, a VR app was created to teach students about the design and construction of steel structures, called the Steel Sculpture App (SSA). The SSA served as a VFT, and the location of the steel frame structure served as the actual field trip (AFT). The research was conducted in structure-related courses in the spring, summer, and fall of 2021 and the spring and fall of 2022 semesters. Each semester, students were split into groups, one being the control group and the other being the experimental group. The control groups learned through AFTs, whereas the experimental groups learned through VFTs. A knowledge test was administered at the end of each treatment to collect quantitative data on the students’ performance, understanding, and knowledge retention. The results indicated that the students learning from VFTs scored higher than those learning from AFTs. The paper discusses student assessment results and student feedback about replacing AFTs with VFTs in times of need.","PeriodicalId":50645,"journal":{"name":"Computer Animation and Virtual Worlds","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135203257","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing methods for complex motion synthesis often require secondary post-processing to eliminate foot sliding to yield satisfied motions. In this paper, we analyze the cause of the sliding issue attributed to the mismatch between root trajectory and motion postures. To address the problem, we propose a novel end-to-end Spatial-Temporal transformer network conditioned on foot contact information for high-quality keyframe-based motion synthesis. Specifically, our model mainly compromises a spatial-temporal transformer encoder and two decoders to learn motion sequence features and predict motion postures and foot contact states. A novel constrained embedding, which consists of keyframes and foot contact constraints, is incorporated into the model to facilitate network learning from diversified control knowledge. To generate matched root trajectory with motion postures, we design a differentiable root trajectory reconstruction algorithm to construct root trajectory based on the decoder outputs. Qualitative and quantitative experiments on the public LaFAN1, Dance, and Martial Arts datasets demonstrate the superiority of our method in generating high-quality complex motions compared with state-of-the-arts.","PeriodicalId":50645,"journal":{"name":"Computer Animation and Virtual Worlds","volume":"35 1","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135438298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Simple psychotherapy has difficulty achieving desired therapeutic effects, and ADHD diagnoses in adults and children are increasing. However, e-health games may mitigate the limitations of traditional methods by providing an ecologically relevant experience. In this paper, inspired by psycholinguistics, multimodal interaction, and he Pupil-CR method, we have developed a narrative game therapy with eye-tracking to enhance dyslexia and attention deficit manifestations. Using the situated discourses in the game's interactive narration, ADHD patients can concentrate and reduce anxiety and impulsivity. To evaluate the efficacy in improving attention a controlled trial (N = 48) randomly assigned volunteers in 1:1:1 to an eye-tracking jigsaw game or two control groups. The principal measure was the average difference in attention comparison score (ACS) of the test of variables of attention (TOVA) preintervention and post-intervention periods. Based on significant differences observed between the groups, we concluded the eye-tracking jigsaw game could serve as a viable ADHD intervention for children.","PeriodicalId":50645,"journal":{"name":"Computer Animation and Virtual Worlds","volume":"35 1","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135938324","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
