An average of 795,000 people have a stroke each year in the US and stroke is the leading cause of disability. Even though repetitive rehabilitation exercises on a regular basis are the key for motor recovery after stroke, only about one-third of patients follow prescribed exercise regimens. With the development of computer technologies and wearable devices, numerous mobile-based rehabilitation solutions have been proposed. However, how to quantify observations of motor recovery during and after exercise remains a challenge. Typically, if the smoothness of a patient's movement is improved, it indicates the patient's motor recovery. But the equipment to test the movement smoothness can be costly and inefficient, therefore not suitable for the home environment. In this paper, we introduce a mobile based rehab solution to support home exercises for stroke survivors and demonstrate its effectiveness by visualizing and qualitatively analyzing movement data captured by the proposed app. Specifically, we compute smoothness of movement for 15 patients over a 6-week user study. Exercises are designed and monitored by Occupational Therapy domain experts. We compute smoothness using log-dimensionless jerk (LDLJ) and Spectral Arc Length (SPARC) methods. Additionally, we study the Range of Motion (ROM) for each movement and explore the correlation between ROM and upper extremity movement.

Easy-to-use visualisation tools are essential for identifying patterns in unstructured data as it grows larger and more complicated. The majority of large data visualisation techniques either knowledge of a programming language or access to commercial tools. These days, data is growing in size, and statistical visualisation of the data needs numerous displays to represent all of the data's viewpoints. Model tuning, optimisation, and quick decision-making are greatly aided by the intriguing patterns produced by the models that are visualised. However, traditional techniques like histograms, pie charts, box plots, and bar graphs are typically insufficient to adequately communicate the intriguing pattern that needs to be extracted from massive datasets. As a result, this paper introduces a tree-plot method that uses the h2o package's in-memory node technique to store the enormous dataset in memory. Data. Tree's charting capabilities were employed to display the modelled trees, which were built using an Ada Boosted Model as the underlying learning methods. Visualising the modelled tree and evaluating the effectiveness of the data training process are based on the AUC, RMSE, execution procedure time, and MSE results. © 2025 ieee.

Jazz improvisation is the extemporaneous expression of melody, and musicians commonly base their performances on chord progressions given by lead sheets. It is standard practice to commit a progression to memory by analyzing it for common patterns. This paper presents a visualization design intended to help reduce the amount of cognitive work needed to assimilate a song's chords and harmonic patterns. It does this using color, shapes, and glyphs as visual variables to convey meaning about tonal centers, chord functions, and harmonic structure. © 2022 The Author(s) © 2022 The Eurographics Association.

In the realm of Computational Fluid Dynamics (CFD), the demand for memory and computation resources is extreme, necessitating the use of leadership-scale computing platforms for practical domain sizes. This intensive requirement renders traditional checkpointing methods ineffective due to the significant slowdown in simulations while saving state data to disk. As we progress towards exascale and GPU-driven High-Performance Computing (HPC) and confront larger problem sizes, the choice becomes increasingly stark: to compromise data fidelity or to reduce resolution. To navigate this challenge, this study advocates for the use of in situ analysis and visualization techniques. These allow more frequent data "snapshots"to be taken directly from memory, thus avoiding the need for disruptive checkpointing. We detail our approach of instrumenting NekRS, a GPU-focused thermal-fluid simulation code employing the spectral element method (SEM), and describe varied in situ and in transit strategies for data rendering. Additionally, we provide concrete scientific use-cases and report on runs performed on Polaris, Argonne Leadership Computing Facility's (ALCF) 44 Petaflop supercomputer and Jülich Wizard for European Leadership Science (JUWELS) Booster, Jülich Supercomputing Centre's (JSC) 71 Petaflop High Performance Computing (HPC) system, offering practical insight into the implications of our methodology. © 2023 ACM.

Dense multi-view 3D displays appropriately combined with camera arrays may provide consistently augmented reality, where we enjoy a simple solution of occlusion caused by visual obstructions in the real world as if they were transparent for many users at the same time. In this paper, toward such multi-view systems electrically transmitting light fields beyond visual obstructions, we propose a novel method for real-time dense interpolation of entire 4D light fields acquired by sparse viewpoints. First, we discuss appearances of our proposed multi-view system, while examining how dense 4D light fields should be. Then, we propose a novel method of real-time 4D light field interpolation to develop an inexpensive system by reducing the number of image sensors to acquire 4D light fields. By introducing simple depth estimation from equally-spaced multi-view images without severe increase of computational cost, the novel method significantly improves reconstruction quality of the previously proposed one, that can only work for almost constant depths. Finally, experimental results show that our practical implementation on a GPGPU achieves real-time interpolation of entire 4D light fields while obtaining sufficient quality of reconstructed images. It is even comparable to that of various conventional methods for view interpolation, which depend on high computational cost not suitable for our real-time applications.

Public Data visualization: Analyzing Local Running Statistics on Situated Displays

引用

COMPUTER GRAPHICS FORUM 2021年第3期40卷 159-171页

作者： Coenen, J. Moere, A. Vande Katholieke Univ Leuven Res Design Leuven Belgium

Popular sports tracking applications allow athletes to share and compare their personal performance data with others. Visualizing this data in relevant public settings can be beneficial in provoking novel types of opportunistic and communal sense-making. We investigated this premise by situating an analytical visualization of running performances on two touch-enabled public displays in proximity to a local community running trail. Using a rich mixed-method evaluation protocol during a three-week-long in-the-wild deployment, we captured its social and analytical impact across 235 distinct interaction sessions. Our results show how our public analytical visualization supported passers-by to create novel insights that were rather of casual nature. Several textual features that surrounded the visualization, such as titles that were framed as provocative hypotheses and predefined attention-grabbing data queries, sparked interest and social debate, while a narrative tutorial facilitated more analytical interaction patterns. Our detailed mixed-methods evaluation approach led to a set of actionable takeaways for public visualizations that allow novice audiences to engage with data analytical insights that have local relevance.
