The construction of new liberal arts requires breaking disciplinary barriers and achieving the interdisciplinary integration of liberal arts majors. The teaching reform of cross-disciplinary courses is imperative. Starting from the overview of the Data visualization and Communication course, this paper points out the existing problems in the current teaching. It conducts teaching reform research from several aspects such as the concept of curriculum reform, the design of curriculum content, and the reform of teaching models, and elaborates on the innovative features of the reform. Finally, it summarizes the achievements of the curriculum reform and the direction of continuous reform in the future.

Deep neural networks are widely used in target recognition, image classification, speech signal processing. However, it is quite difficult to understand how deep neural networks complete the tasks from different fields. This paper proposes a method to analyze the principle of deep neural networks for target recognition by applying double-sliding window and dropping features to the model input image samples. First, the input image is divided into several blocks. Then, part of features in each block are removed in turn to observe the effect of the classification results. Finally, the average of the effect from each feature in the input sample on the classification results is calculated. Experimental results prove that the effects of features from the input image on the decisions of classification results are performed well by the method proposed. It can help realize the visualization analysis of target recognition with deep neural networks

A smooth walkthrough between two adjacent viewpoints in three-dimensional (3-D) space is the key idea for increasing interactive experiences. It is a relatively easy task when we have the fully 3-D structure of two points. However, most people need a lot of effort to collect 3-D data, and using them efficiently is even harder. In this paper, we propose an algorithm that can create a realistic and natural panoramic walkthrough through two 360-degree panorama images. We estimate the correlated keypoints between the two images through feature matching by using 360-degree images of two points selected by the user. These key points are connected to each other to create faces. By using the spherical coordinate system, the existing key points can be expanded and more detailed faces can be determined. Using the characteristics of the panorama image, we predict the movement of keypoints in the spherical coordinate system, and through this, we predict and create a 360-degree panorama image just as the user moves between the two adjacent images. When moving the space between two points, the users can experience a virtual world through a 360-degree image of the space. With this algorithm, we can access the free view of the rotation and translation of the space by using only the 360 degrees panorama image of the two adjacent points. Hence, we validate our result with the MOS test on various walkthrough situations and our proposed algorithm shows the most preference among users compared to prior algorithms.

Animated hand-drawing sketches are a common way to communicate concepts and information. Sketches are also used to query charts, interact with visualizations, or express rough designs. However, there is little work investigating how people manually create visualization sketches and whether animated sketches can help users understand charts. We first conduct a user study that collects the sketching processes of people with visualization knowledge and then summarize the patterns in the sketch order. Based on the sketch patterns, we conduct a between-subject study to evaluate whether animated sketches can improve users’ performance of visualization tasks. We discuss the results of the user study and future work on evaluating the effectiveness of animated sketches.

This paper presents a solution for visualizing oil spills at sea by combining satellite data with virtual choreographies. The system enables dynamic, interactive visualization of oil slicks, reflecting their shape, movement, and interaction with environmental factors like currents and wind. High-resolution geospatial data supports a multiplatform experience with aerial and underwater perspectives. This approach promotes independence, interoperability, and multiplatform compatibility in environmental disaster monitoring. The results validate virtual choreographies as effective tools for immersive exploration and analysis, offering structured data narratives beyond passive visualization—especially valuable for mixed reality applications.

The electrical generator data across the United States with a minimum capacity of one megawatt is publicly accessible via the US Energy information Administration form 860 (EIA-860). It is a valuable resource, holding significance for power and energy researchers as well as industry professionals. This paper describes the development and application of a power flow model utilizing the EIA-860 dataset. Beyond the model development process, this research emphasizes the critical role of effective data visualization techniques in communicating essential information about electricity generation. By showcasing the dataset's versatility and analytical power, this paper allows users to make informed decisions to advance power flow and generation adequacy studies.

Although the incorporation of sensing, actuators, and controllers make robots powerful systems, simulating them is a big challenge. While it is possible to assemble a simulator from the innumerable graphics, kinematics, physics and libraries, the architecture and control procedure are crucial to shaping the interaction of these elements and consequently the general performance of the robotic system. This paper reviews the capability of two different robotic simulation platforms to simulate different robotic systems that allow for direct interface of various control techniques implemented in MATLAB. This direct interface with Augmented Reality (AR) and simulation models allows more accessibility to test and evaluate the designed control systems to a general-public by reducing the model operation complexity. Using AR simulators reduces the cost, strengthens productivity, and increases the quality of design by offering a flexible diagnostic and evaluation method using AR.
