The ubiquity of mobile technology and advances in wearable health and well-being technologies offer exciting opportunities for technology supported home and community care. But are we ready for digitally enabled self-care? How can the CHI community share best practices and methods in order to continue to advance research that crosses methodological and cultural boundaries between Health and HCI? This workshop will bring together key researchers working in and across both HCI and Health to share these existing challenges and opportunities for digital health research and practice and to continue to build capacity in the crossings between HCI and health.

Underwater sites are a challenging environment for augmented reality. Images taken under water are degraded in several ways, most importantly they are affected by unbalanced colors due to uneven absorption of light in each color channel, blurring and desaturation caused by turbidity, or noise due to the presence of larger organisms, plants, or bubbles. In this paper, we introduce a new method based on white balancing that enhances underwater images to improve the results of detection of markers. We compare this method with several image enhancement methods, and evaluate their performance when applied to the problem of detecting markers under water. Our results show that our method improves the detection in underwater environments while keeping the computation time low. © 2018 GCH 2018 - Eurographics Workshop on Graphics and Cultural Heritage.

Smart solutions provide increasing quality and availability of data. This brings new challenges for designers as it offers novel design opportunities and interlaces disciplines. At the same time, physical inactivity is a big societal challenge and dedicated urban planning and design can contribute to more active lifestyles. In this paper, we investigate how user-generated big data can support designers in shaping more activity-friendly and adaptive environments, addressing both timely challenges. Bridging the fields of HCI and urbanism, we introduce two data lenses. The individual lens primarily builds on empathic design skills and calls for a highly personal approach. The collective lens emphasizes systematic and holistic design skills, focusing on creating overview and surfacing collective interests. Through exploratory data visualizations, using a large dataset from a run-tracking smartphone application combined with public data sources, and a workshop, we investigate how these lenses can yield meaningful insights. We discuss the value of these lenses to the urban design and HCI communities and address the challenges and opportunities that arise at the cross-section of these perspectives. © 2024 Copyright held by the owner/author(s).

Despite the success in developments of wind energy technology, there remain challenges, for example, in offshore wind energy installation. Due to changeable and unstable offshore weather conditions, it is hard to effectively schedule the installation logistics. In this work, we propose a simulation-based scheduling strategy to help the operators and the project managers, to make the main decisions during the installation to increase efficiency, e.g. how many offshore wind turbines should be loaded onto the installation vessel. The offshore logistic concept is modeled using timed Petri nets (TPN) approach. The timed transitions in the TPN model are assigned with operation times estimated by means of discrete-time Markov chain (DTMC) approach, which uses historical weather data. Besides, operability is introduced in this work as an indicator to evaluate schedules of a certain time period. © 2020 Society for Modeling & Simulation International (SCS)

作者： Ke Li Tim Rolff Susanne Schmidt Reinhard Bacher Simone Frintrop Wim Leemans Frank Steinicke Department of Informatics Human-Computer Interaction Group Universität Hamburg Deutsches Elektronen-Synchrotron DESY Germany Department of Informatics Computer Vision Group Universität Hamburg

Neural radiance field (NeRF), in particular, its extension by instant neural graphics primitives is a novel rendering method for view synthesis that uses real-world images to build photo-realistic immersive virtual scenes. Despite its enormous potential for virtual reality (VR) applications, there is currently little robust integration of NeRF into typical VR systems available for research and benchmarking in the VR community. In this poster paper, we present an extension to instant neural graphics primitives and bring stereoscopic, high-resolution, low-latency, 6-DoF NeRF rendering to the Unity game engine for immersive VR applications. 1 1 Link to the repository: https://***/uhhhci/immersive-ngp

We present a new context-aware method for lexical simplification that uses two free language resources and real web frequencies. We compare it with the state-of-the-art method for lexical simplification in Spanish and the established simplification baseline, that is, the most frequent synonym. Our method improves upon the other methods in the detection of complex words, in meaning preservation, and in simplicity. Although we use Spanish, the method can be extended to other languages since it does not require alignment of parallel corpora. © 2015 Association for Computational Linguistics.

International Conference on Image Analysis and Processing

作者： Yulia Gizatdinova Veikko Surakka Research Group for Emotions Sociality and Computing Tampere Unit for Computer-Human Interaction Department of Computer Sciences University of Tampere Finland

The present aim was to develop a fully automatic feature-based method for expression-invariant detection of facial landmarks from still facial images. It is a continuation of our earlier work where we found that some certain muscle contractions made a deteriorating effect on the feature-based landmark detection especially in the lower face. Taking into account this crucial facial behavior, we introduced improvements to the method that allowed facial landmarks to be fully automatically detected from expressive images of high complexity. In the method, information on local oriented edges was utilized to compose edge maps of the image at two levels of resolution. The landmark candidates resulted from this step were further verified by edge orientation matching. We used knowledge on face geometry to find the proper spatial arrangement of the candidates. The results obtained demonstrated a high overall performance of the method while testing a wide range official displays.

Medical care, particularly for chronic diseases, accumulates a huge amount of patient data over extensive time periods that needs to be accessed and analyzed accordingly. Information Visualization methods hold great promises in turning data deluge into improved quality of medical care. Yet, patient data management systems mostly provide documents, form-based displays, or static visualizations. We present a design study of an interactive visualization system, called VisuExplore, to support long-term care and medical analysis of patients with chronic diseases. VisuExplore offers interaction techniques for effective exploration of time-oriented data and employs simple, but intuitive visualization techniques. It was developed in close cooperation with physicians. We conducted two user studies with nine physicians and 16 students, which indicate that our design is useful and appropriate for particular tasks. © 2011 Springer-Verlag Berlin.

Neural radiance field (NeRF), in particular its extension by instant neural graphics primitives, is a novel rendering method for view synthesis that uses real-world images to build photo-realistic immersive virtual scenes. Despite its potential, research on the combination of NeRF and virtual reality (VR) remains sparse. Currently, there is no integration into typical VR systems available, and the performance and suitability of NeRF implementations for VR have not been evaluated, for instance, for different scene complexities or screen resolutions. In this paper, we present and evaluate a NeRF-based framework that is capable of rendering scenes in immersive VR allowing users to freely move their heads to explore complex real-world scenes. We evaluate our framework by benchmarking three different NeRF scenes concerning their rendering performance at different scene complexities and resolutions. Utilizing super-resolution, our approach can yield a frame rate of 30 frames per second with a resolution of 1280×720 pixels per eye. We discuss potential applications of our framework and provide an open source implementation online.1 Copyright © 2022, The Authors. All rights reserved.
