Playing for a Better Future: How Animal Avatars Influence the Attitude of Players

Proceedings of the ACM on Human-computer Interaction 2024年第CHI PLAY期8卷 1-25页

Digital games allow us to adopt the avatar’s perspective and experience the (virtual) world from another point of view. The positive effects of such role swaps are well-documented in contexts such as combating racial or ethnic biases. Our work expands this research direction by considering animal avatars: We hypothesize that playing as an animal can improve our attitude towards wildlife and nature. In particular, this manuscript contributes a first systematic study on the effects of animal avatars on players’ implicit attitudes towards animals. Our study (N = 78) employs two commercial games featuring different animal avatars, Endling - Extinction is Forever and Bee Simulator, and compares the results of implicit association tests administered before and after gameplay. Our findings confirm significant positive effects of the games on players’ implicit associations with foxes and bees. Together with several interesting insights regarding player-avatar relationships and avatar identification, our work paves the groundwork for games contributing positively to societal change. © 2024 Copyright held by the owner/author(s).

IEEE Transactions on visualization and computer Graphics 2023年第1期29卷 1288-1298页

Stylized tubes are an established visualization primitive for line data as encountered in many scientific fields, ranging from characteristic lines in flow fields, fiber tracks reconstructed from diffusion tensor imaging, to trajectories of moving objects as they arise from cyber-physical systems in many engineering disciplines. Typical challenges include large data set sizes demanding for efficient rendering techniques as well as a large number of attributes that cannot be mapped simultaneously to the basic visual attributes provided by a tube-based visualization. In this work, we tackle both challenges with a new on-tube visualization approach. We improve recent work on high-quality GPU ray casting of Hermite spline tubes supporting ambient occlusion and extend it by a new layered procedural texturing technique. In the proposed framework, a large number of data set attributes can be mapped simultaneously to a variety of glyphs and plots that are embedded in texture space and organized in layers. Efficient rendering with minimal data transfer is achieved by generating the glyphs procedurally and drawing them in a deferred shading pass. We integrated these techniques in a prototype visualization tool that facilitates flexible mapping of data set attributes to visual tube and glyph attributes. We studied our approach on a variety of example data from different fields and found it to provide a highly adaptable and extensible toolbox to quickly craft tailor-made tube-based trajectory visualizations. © 2022 IEEE.

Accurate modeling of material appearance is crucial for achieving predictive rendering. To improve reflection models, databases with measured reflection behaviors of various material and surface types are of great importance. However, current databases provide limited information, focusing either on the spectral or spatial domain and often lack microgeometry details. To address this limitation, a multi-modal database that includes reflection behavior in both spectral and spatial domains, along with comprehensive microgeometry information, is essential. Additionally, scatter information simulated with microgeometry enhances the understanding of light-matter interactions. This paper discusses the importance of multi-modal reflection data in developing more realistic and computationally efficient reflection models for predictive rendering. © 2024 The Authors.

The restricted input queue (rique) is a data structure which is recently introduced to study linear layout of graphs. The rique data structure is a special queue where insertions occur only at the head and removals occur at both the head and the tail. Considering a rique data structure the goal of a linear layout of a graph is to find a linear order of the vertices of the graph and a partition of its edges into pages such that the edges in each page follow the restriction of rique in the underlying order. The rique number of a graph is the smallest number of pages required for linear layout of the graph with rique data structure. A characterization of graphs for admitting a single page rique layout and some bounds on the rique number of complete and complete bipartite graphs are known. In this paper, we show that the rique number of series-parallel graphs as well as planar bipartite graphs is 2. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.

The growth of the skin care industry is driving consumers to look for product review information. The skincare product currently widely used by women and men is facial wash products. On the Female Daily website, the most frequently purchased facial wash products are Cetaphil products. With so many purchases of this product, potential buyers want to try the product by reading the reviews first. However, the large number of reviews is a barrier to accessing relevant information. Therefore, effectively summarizing reviews can solve this problem by presenting key information more concisely and digestibly. This study aims to evaluate the effectiveness of three different summary methods, namely BERT, BART, and T5, in summarizing skin care product reviews. The stages in these three models are explained in detail. Evaluation results using the ROUGE Score method with the Cetaphil facial wash product review dataset show that the BART model consistently has a higher average ROUGE Score than the BERT and T5 models. Specifically, the BART model achieved an average ROUGE-1 of 0.87718, ROUGE-2 of 0.80689, and ROUGE-L of 0.87688, while the BERT model achieved an average ROUGE-1 of 0.84591, ROUGE-2 of 0.77585, and ROUGE- L is 0.84479, and model T5 has an average ROUGE-1 of 0.74995, ROUGE-2 of 0.70048, and ROUGE-L of 0.73023. These results suggest that the generative approach implemented by BART is more effective in addressing the diversity and complexity of skin care product reviews. Therefore, using the BART model is a better choice for producing skin care product review summaries that are more informative and useful for consumers. In the future, these findings may contribute to developing more sophisticated product review summary systems. © 2023 IEEE.

Enhancing immersive environments in an efficient way is essential across various industries. However, the task of selecting and placing suitable objects to decorate 3D scenes often requires a substantial investment of time and expertise. We present a novel semi-automatic approach to accelerate this process by fusing state-of-the-art generative text-to-image models with object detection. We use a rendering of a plain 3D scene as input for Stable Diffusion and generate an image depicting a decorated version. With object detection, we identify the location, size and class of decorative elements in the generated image. Based on this information, we populate the original 3D scene with matching assets from a database. Our results demonstrate the capabilities of our proposed approach in enhancing 3D scenes through the incorporation of decorative models across different scenarios. We show that our method seamlessly integrates into existing 3D content creation tools highlighting its applicability within established workflows. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.

Wave Function Collapse (WFC) is a powerful generative algorithm, able to create locally-similar output based on a single example input. One of the inherent limitations of the original WFC is that it often requires users to understand its inner workings, and possibly make their own ad-hoc mods, to achieve satisfactory results. Besides distracting from your creative task, this strongly reduces the algorithm's effective usefulness to a small group of technical users. We propose miWFC, a novel mixed-initiative approach to WFC aimed at overcoming these drawbacks. Its main focus is on providing intuitive control to its users, in a way that matches their usual creative workflow. Among its main features, this approach provides (i) interactive navigation through design history, including controlled backtracking, (ii) precise manual editing of the output for direct expression of design intent, and (iii) interactive manipulation of tile weights, to tweak the global appearance of the output. We evaluated a prototype implementation of our approach among game artists and other creative professionals, and concluded that its features were largely considered useful and supportive of their creative work. © 2022 Owner/Author.

Semi-Supervised Domain Adaptation (SSDA) aims to develop domain invariant models from scarcely labeled target domain in addition to the fully labeled source domain. Current SSDA works are often applied in conjunction with ResNet34 backbone, which makes them overlook the advantages of utilizing other backbones. Hence, in this paper, we investigate the impact of employing different modern backbones in SSDA and propose a novel solution named Modern Backbones Assisted Co-training for Rapid and Robust Semi-Supervised Domain Adaptation (MARRS), that uses discriminative features of two modern backbones for training linear classifiers using the well established co-training framework. To induce diversity among classifiers for effective co-training, we propose a novel module that produces diversity at three levels, namely image, backbone, and feature distribution levels. Experiments reveal that MARRS not only achieves state-of-the-art performance across all popular SSDA datasets, but also drastically cuts the computation time compared to other SSDA approaches, making MARRS a rapid and robust solution for SSDA. We also provide extensive ablation experiments to verify our framework's vitality and primary design choices. © 2023 IEEE.

The performance of deep neural networks for image recognition tasks such as predicting a smiling face is known to degrade with under-represented classes of sensitive attributes. We address this problem by introducing fairness-aware regularization losses based on batch estimates of Demographic Parity, Equalized Odds, and a novel Intersection-over-Union measure. The experiments performed on facial and medical images from CelebA, UTKFace, and the SIIM-ISIC Melanoma classification challenge show the effectiveness of our proposed fairness losses on bias mitigation as they improve model fairness while maintaining high classification performance. To the best of our knowledge, our work is the first attempt to incorporate these types of losses in an end-to-end training scheme to mitigate biases of visual attribute predictors. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.
