5th European Tangible Interaction Studio, ETIS 2022

作者： Echeverri, Daniel Department of Visual Computing Faculty of Informatics Masaryk University Brno Czech Republic

This paper expands on previous work on tangible narratives. It briefly reviews the design case of Letters to José, from which stemmed a narrative architecture for tangible narratives and a typology that frames the qualities of tangible artifacts with narrative meaning. Based on this architecture and exemplified in the typology, the paper introduces The Non-myth of the Noble Red, a tangible narrative which expands upon the learnings gained from the design of Letters to José. This paper presents some of its technological considerations and discusses how it integrates Brechtian theatre concepts to explore alternative digital storytelling approaches. © 2022 Copyright for this paper by its authors.

MPI performance analysis tools are important instruments for finding performance bottlenecks in large-scale MPI applications. These tools commonly support either the profiling or the tracing of parallel applications. Depending on the type of analysis, the use of such a performance analysis tool may entail a significant runtime overhead on the monitored parallel application. However, overheads can occur in different stages of the performance analysis with varying severity, e.g., the overhead when initializing an MPI context is typically less problematic than when monitoring a high number of short-lived MPI function calls. In this work, we precisely define the different types of overheads that performance engineers may encounter when applying performance analysis tools. In the context of performance tuning, it is crucial to avoid delaying individual events (e.g., function calls) when monitoring MPI applications, as otherwise performance bottlenecks may not show up in the same spot as when running the applications without applying a performance analysis tool. We empirically examine the different types of overheads associated with popular performance analysis tools for a set of well-known proxy applications and categorize the tools according to our findings. Our study shows that although the investigated MPI profiling and tracing tools exhibit a rather unique overhead footprint, they hardly influence the net time of an MPI application, which is the time between the Init and Finalize calls. Performance engineers should be aware of all types of overheads associated with each tool to avoid very costly batch jobs. © 2022 ACM.

Spinal X-rays are widely used for screening and preliminary diagnosis of adolescent scoliosis due to their low cost and minimal radiation exposure. To enhance the accuracy of scoliosis measurements and alleviate the burden on physicians, the goal in this field has been to achieve fully automated spinal curvature measurements under the assistance of computer technology. In this paper, an analysis is conducted on existing computer assisted methods for measuring scoliosis across various image modalities. These methods are categorized into three groups based on their contributions to the automation of scoliosis measurement: automated scoliosis localization, automated curvature feature extraction, and automated classification of scoliosis severity levels. In the end, the problems existing in the current research progress are highlighted and possible solutions are discussed for achieving fully automated measurement of spinal curvature on X-rays.

The iterative nature of agile requirements engineering often requires considerable time and effort. Research on automation processes with artificial intelligence for agile requirements engineering practices has gained popularity in recent years. The objective of this study is to conduct a systematic literature review and report the current state of artificial intelligence integration in agile requirements engineering. 24 papers were selected for the analysis. From the papers included in the study, it was found that the most popular requirements engineering activity currently being researched with artificial intelligence is requirement analysis and documentation, with natural language processing tools combined with machine learning as the most used artificial intelligence tool. The levels of automation were still mostly at level 3 and level 4. Similar to related works, this indicates that the implementation of agile requirement engineering largely depends on humans.

News recommendation schemes use features of the news and user information to suggest relevant news items based on their interests. However, existing schemes are not very effective for new users who have little activity history. To address this issue, we have developed a hybrid news recommender system that combines content-based and collaborative filtering approaches, along with user demographic data. We conducted an extensive experiment using a dataset of news articles, user ratings, and demographic data to evaluate the system's effectiveness. We assessed the system's performance through two experiments. The first experiment focused on individual user similarity and achieved a precision of 68.05%, a recall of 42.46%, and an average F1 score of 52.1%. The second experiment examined user similarity within the same category, resulting in a precision of 93.75%, a recall of 40.25%, and an F1 score of 56.31%. These results indicate that the proposed model performs better in the second experiment compared to the first.

This study explores the effectiveness of the multiplayer serious mobile game "Zirkus Empathico (ZE) 2.0" in enhancing social-emotional behaviors in children diagnosed with autism spectrum disorder (ASD). It aims to assess how such games can foster emotional recognition, empathy, and prosocial behavior, thereby supporting the holistic development of children with ASD. An eight-week randomized controlled trial (RCT) was conducted between January and April 2021 at autism centers in Islamabad, Pakistan, and Berlin, Germany. The study involved 107 children aged 5–11 years, with 60 diagnosed with ASD and 47 typically developing children serving as an Active Control Group (ACG). Participants were engaged in sessions using the bilingual"ZE 2.0"game, incorporating multiplayer and emotional learning modules. The intervention required 120 min of weekly training supplemented by daily sessions. Post-intervention assessments demonstrated significant improvements in the ASD group compared to the control group in areas of empathy and emotional awareness, as evidenced by higher scores on the Griffith Empathy Measure (GEM) and multiplayer module evaluations. Notable was the ability of participants to apply learned social skills in dynamic, real-world contexts, which suggests the game’s effectiveness transcends the controlled settings typically associated with ASD interventions. ZE 2.0 adds to the social and teamwork competencies of children with ASD. Besides encouraging peers to be proactive in communications and cooperation, the multiplayer mode provides an immersion learning atmosphere for facilitating social and emotional development. Such an outcome underlines the perspectives of serious games for use as a framework for the treatment and education of children who have ASD. In this manner, serious games can be utilized as a supplementary or alternative means of treating ASD. Future research may focus on distinguishing the effects of intervention from those of other therapy modalit

Given the increasing demand for laboratory equipment management in universities, especially the increasingly complex equipment management, the traditional equipment management system can no longer meet the management needs of universities. Therefore, it is very important to optimize the university's equipment management system. The allocation of laboratory equipment maintenance tasks in the laboratory equipment management system of universities is a very critical link. Its effective solution is crucial to ensure the normal operation of laboratory equipment and the reasonable allocation of maintenance resources. This study proposes a double coding adaptive genetic algorithm to optimize the allocation of laboratory equipment maintenance tasks in universities to achieve the optimal allocation of resources and minimize maintenance costs. The work allocation scheme is iteratively optimized by a dual-coding strategy and definition of adaptive crossover and mutation operators. The experimental results of this study show that the algorithm can find the approximate optimal task allocation scheme within a reasonable time, which improves the efficiency and accuracy of laboratory equipment maintenance. In addition, compared with the traditional allocation method, the algorithm in this paper shows stronger flexibility and robustness when dealing with large-scale complex problems. © 2024 The Authors.

Agriculture is critical to ensuring and securing food supply for human consumption. Paddy crops are an agricultural practice that produces one of the highest food yields in agriculture. Paddy diseases must now be detected and diagnosed as soon as possible rather than later. Farmers currently use the naked eye to observe suspected infected paddies. The suspected infected paddy will then be sampled and sent to the laboratory for further examination. These methods are highly inefficient, time-consuming, and error prone. Most paddy farmers lack the knowledge to make an informed and accurate diagnosis of which paddies are infected by which diseases. This paper explores using deep learning algorithms to detect and classify various paddy diseases automatically. This method will take an image of paddy leaves and classify it based on the disease category indicated by the idea. The PaddyDoctor dataset from the Kaggle website was used to train and test the deep-learning models. Convolutional Neural Network (CNN) and Transfer Learning models, including MobileNet, MobileNetv2, and InceptionV3, have been constructed. The results of an experiment involving different dataset split ratios, learning rates, and batch sizes. CNN with MobileNetV2 outperformed CNN with MobileNetV1 and CNN with InceptionV3 by 98.05 percent, 80.08 percent, and 83.98 percent, respectively. © 2023 IEEE.
