Wheel loaders need an interactive interface to collect and display the posture information when they operate in a harsh environment. This paper proposes a visualization interface for posture monitoring of wheel loaders. It is driven by the data from the inertial measurement system based on attitude heading reference system, including a real-time three-dimensional animation display system created using OpenGL. The proposed system could be effectively used for monitoring the body posture of wheel loaders under the influence of the external environment. Experimental results are presented to show the good accuracy and real-time performance of the proposed monitoring system. Moreover, the proposed system could enhance vehicle safety, remote operability, and human-vehicle interaction.

In this paper the application of visualization to aid in trade-off decisions when solving multi-objective optimization problems involving coupled subsystems under uncertainty is presented. The developed visualization method is an abstract way of representing these problems for use in a solution process where multiple resultant design points may exist. In these cases, a designer must consider potentially complex trade-off decisions in order to choose a point with which to proceed. Designers can examine the coupled subsystem design space under different uncertainty conditions through three-dimensional. visual representations. Promising solution regions can be determined and explored down to a specific design point. As a result, the time to locate a trade-off solution for all subsystems has the potential to substantially decrease. This paper presents background into the type of problems being addressed as well as other visualization methods used in design. The method development is presented along with the results and discussion of a test case to illustrate the method's viability.

Osteoarthritis (OA) of the knee can be described as the degradation and loss of articular cartilage. Adequate visualization of cartilage is paramount in allowing accurate and clinically meaningful assessment of cartilage surface morphology and thickness. In this paper we present a web-based user interface that allows the visualization of quantitative results (i.e., cartilage thickness) derived from MR knee images. The use of web-based technology has allowed greater access to the interface and clinically useful interactive functions for the viewing of data (i.e., cartilage thickness WearMap and MR images).

A Deep Generative Model for Reordering Adjacency Matrices

IEEE TRANSACTIONS ON visualization AND COMPUTER GRAPHICS 2023年第7期29卷 3195-3208页

Depending on the node ordering, an adjacency matrix can highlight distinct characteristics of a graph. Deriving a "proper" node ordering is thus a critical step in visualizing a graph as an adjacency matrix. Users often try multiple matrix reorderings using different methods until they find one that meets the analysis goal. However, this trial-and-error approach is laborious and disorganized, which is especially challenging for novices. This paper presents a technique that enables users to effortlessly find a matrix reordering they want. Specifically, we design a generative model that learns a latent space of diverse matrix reorderings of the given graph. We also construct an intuitive user interface from the learned latent space by creating a map of various matrix reorderings. We demonstrate our approach through quantitative and qualitative evaluations of the generated reorderings and learned latent spaces. The results show that our model is capable of learning a latent space of diverse matrix reorderings. Most existing research in this area generally focused on developing algorithms that can compute "better" matrix reorderings for particular circumstances. This paper introduces a fundamentally new approach to matrix visualization of a graph, where a machine learning model learns to generate diverse matrix reorderings of a graph.

A Novel interface for Interactive Exploration of DTI Fibers

Visual exploration is essential to the visualization and analysis of densely sampled 3D DTI fibers in biological speciments, due to the high geometric, spatial, and anatomical complexity of fiber tracts. Previous methods for DTI fiber visualization use zooming, color-mapping, selection, and abstraction to deliver the characteristics of the fibers. However, these schemes mainly focus on the optimization of visualization in the 3D space where cluttering and occlusion make grasping even a few thousand fibers difficult. This paper introduces a novel interaction method that augments the 3D visualization with a 2D representation containing a low-dimensional embedding of the DTI fibers. This embedding preserves the relationship between the fibers and removes the visual clutter that is inherent in 3D renderings of the fibers. This new interface allows the user to manipulate the DTI fibers as both 3D curves and 2D embedded points and easily compare or validate his or her results in both domains. The implementation of the framework is GPU-based to achieve real-time interaction. The framework was applied to several tasks, and the results show that our method reduces the user's workload in recognizing 3D DTI fibers and permits quick and accurate DTI fiber selection.

Many adults suffer from osteoarthritis (OA) with the majority of people over 65 showing radiographic evidence of the disease. To carry out effective diagnosis and treatment, it is necessary to understand the progression of cartilage loss and study the effectiveness of therapeutic interventions. Hence, it is important to have accurate, fast diagnosis of the disease. In this paper, we describe a Web-based user interface that enables the direct viewing of 2-D and 3-D image data from the visceral and tissue levels of the biological continuum (i.e., the continuum comprising systems, viscera, tissue, cells, proteins, and genes)-while preserving geometric integrity. This is achieved despite the fact that the data are from different modalities (i.e., magnetic resonance (MR) and tight microscopy). The user interface was tested using image data acquired from a study of articular cartilage thickness in the porcine knee. The interface allows the clinician to view both MR and light microscopy images in an integrated manner-with the information linked geometrically.

Medical applications and clinical environments set new demands on sensor network technologies, one of the key research areas in computer science and health telemonitoring. This paper presents a wireless systematic architecture, a hardware and software platform based on low-power integrated circuits, on-chip signal processing components and communications. The structure of such architecture consists of lightweight miniature nodes placed strategically on patients to allow non-invasive, continuous and ambulatory health monitoring and inexpensive, to provide medical readings on local devices and clinical records applications on web browsers and mobile devices. The main goal of this project is the development of an autonomous wireless monitoring system for vital signs with battery-powered nodes and medical sensors. It acquires, stores and transmits signals to determine the states of oxygenation, heart and respiratory rates, and temperature in real time to a central monitoring station, that integrates a touchscreen graphical interface and mini-OLED displays. This work provides self-monitored environments minimizing the requirements for primary needs, early medical attention, optimizing premature diagnosis and comfort of patients, through a set of algorithms that contribute to the performance of the nodes generating significant benefits on human lifetime through early disease detection.

The visual attributes such as shape, color, size have been considered as the most basic form of information encoded in geographic information visualization interface;however, the optimal multi-visual coding forms and reasonable quantity are not well defined, nor has it been determined whether the advantage of one-attribute coding is maintained across different multi-visual coding. In this study, we choose four typical visual attributes (text, shape, color, size) in geographic information visualization and argue that the effects of multi-visual coding are affected by the coding forms and the levels of quantity. Our experiment used a within-subjects design, with independent variables of four visual attributes (text, shape, size, color) and the number (1, 2, 3, 4) of visual attributes in multi-visual coding forms. The results support the effects of multi-visual coding in geographic information visualization are modulated not only by the coding characteristics of each visual attribute, but also by the forms and the number of visual attributes in the coding forms.
