In the age of big data, high-dimensional and complex data create significant challenges for data visualization. This research analyzes their impact on visualization techniques. Increasing data dimensions make traditional methods struggle to depict complex structures and patterns. This study comprehensively explores challenges arising from high dimensionality and data complexity in visualization. By examining various techniques and their suitability for such data, we aim to reveal the pros and cons of each approach in conveying essential information. Additionally, this research investigates using dimension reduction techniques to tackle the complexities of the data. The effectiveness of these techniques in preserving crucial information while enhancing visualization quality is evaluated. Some of the models examined include Multidimensional Scaling (MDS), which projects data into a lower-dimensional space to maintain distance relationships but does not consider class labels. MDS operates with a distance matrix but is sensitive to data that do not conform to distance metrics and can yield suboptimal projections in high-dimensional space. Principal Component Analysis (PCA) focuses on dimension reduction by maximizing data variance but does not consider class labels. PCA requires high-dimensional data and cannot handle non-linear structures. Linear Discriminant Analysis (LDA) is used for classification by maximizing inter-class distances, minimizing intra-class distances, and requiring class labels. However, LDA works well only under the assumptions of normal distribution and fulfilled class variance differences. Conversely, t-SNE and UMAP reveal data cluster structures. t-SNE is computationally complex and sensitive to parameters, while UMAP performs faster. t-SNE interprets data with topological and network context, suited for data with strong topological structures but requiring deep domain knowledge. Each method has its uses and limitations, depending on analysis goa

Operating heavy machinery is challenging and can pose safety hazards for the operator and bystanders. Although commonly used augmented reality (AR) devices, such as head-mounted or head-up displays, can provide occupational support to operators, they can also cause problems. Particularly in off-highway scenarios, i.e., when driving machines in bumpy environments, the usefulness of current AR devices and the willingness of operators to wear them are limited. Therefore, we explore how laser-projection-based AR can help the operator facilitate their tasks and enhance safety. For this, we present a compact hardware unit and introduce a flexible and declarative software system. Furthermore, we examine the calibration process to leverage a camera projector setup and outline a process for creating images suitable for display by a laser projector from a set of line segments. Finally, we showcase its ability to provide efficient instructions to operators and bystanders and propose concrete applications for our setup.

This work presents an in-depth analysis of load profile data utilizing the bootstrap method, emphasizing the importance of data management and visualization in electricity consumption patterns. By exploring load profiles from different substations, this study leverages various techniques to predict and analyse data patterns and visualizations effectively. Using R language tools, the paper navigates through the bootstrap method, illustrating the approach with visualizations of yearly, weekly, and seasonal data distributions across three substations. It brings to light the variations in electricity demand and highlights the efficiency of the bootstrap method in evaluating errors in statistical measurements without relying on traditional assumptions. The research indicates that modern computing capabilities can effectively execute multiple iterations of the bootstrap method, offering valuable insights into statistical parameters, including variance and standard deviation. In addition, this work provides a framework for understanding energy usage trends over various timescales, essential for pinpointing periods of peak demand.

This study presents an innovative approach to understanding differences in student comprehension in online programming courses by analyzing note-taking and questioning patterns and the distribution of grades. It enables instructing educators to understand learners' learning behaviors better. We designed and developed a system to support online learning that enables students to take notes and ask questions while viewing online courses and allows instructors to grasp overall feedback. We used a visualization method based on the location of notes and questions as they appear in the learning videos to enable instructors to capture their learners' learning better. Visualizing the distribution of notes and questions shows differences among students' note-taking patterns and learning strategies. The underlying comprehension patterns involved lead to differences in the patterns of notes and questions. We compared data from learners in different score bands to verify the correlation between note types and scores. By visualizing and comparing notes with the same type of correlation, the results show the correlation between note types and grades and the potential of the visualization method to analyze students' learning strategies and learning personalities. It provides valuable insights into student engagement, comprehension, and learning strategies, which can inform the development of more effective teaching methods. This study is relevant in the contemporary educational landscape, particularly as many institutions transition to online formats. Detecting student engagement and comprehension levels in these contexts is crucial.
