Title: Interactive Visualizations for Crime Data Analysis by Mixed Reality
Crime data visualization plays a key role in understanding and dealing with criminal activities. This paper focuses on the integration of mixed reality (MR) and crime data analysis. There are many barriers and challenges when developing MR three-dimensional (3D) environments for visualization and inspection. The main problem is the lack of commonly shared data structures and interfaces between them. The rise in crime rates over the past few years is a huge source of issue for police departments and law enforcement organizations. As the crime rates significantly changed throughout time, both upward and downward, these changes are then compared to external factors, such as population, unemployment, and poverty. There is a need for visualizing the multiple crime datasets in multiple states with external factors. This work proposes a novel interactive approach for loading crime datasets into the HoloLens 2 device and displaying them in a mixed-reality setting for data analysis. By allowing people to engage and analyze datasets in a 3D space, the suggested system seeks to close the gap between data analysis and machine learning. Users can import many datasets, such as spatial, category, and numerical data, into the HoloLens 2 device and interactively visualize crime data for different states simultaneously. The system offers user-friendly capabilities for interactive data visualization in mixed reality once the data has been imported. The dataset is manipulated and transformed by users, who can also rotate, scale, and position it in 3D. To depict various characteristics and dimensions of the data, the system also supports a variety of visual encoding techniques, such as color mapping, size scaling, and spatial layout with the use of the imported datasets and the HoloLens 2’s visualization capabilities, users can discover new insights and intricate linkages within the data. Natural movements and voice instructions allow users to engage with the visible data, enabling a hands-free and immersive data exploration experience. This paper also visualizes the crime data for four different cities: Chicago, Baltimore, Dallas, and Denton. Analyzing crime against factors such as population, employment, unemployment rate, and poverty rates provides information about the complex relationship between social factors and criminal behavior. The results and outcomes of this work will help the police department and law enforcement organizations better understand crime issues and supply insight into factors affecting crime that will help them deploy resources and help their decision-making process.  more » « less

    The rise in crime rates over the past few years is a major issue and is a huge source of worry for police departments and law enforcement organizations. Crime severely harms the lives of victims and the communities they live in many places throughout the world. It is an issue of public disturbance, and large cities often see criminal activity. Many studies, media, and websites include statistics on crime and it is contributing elements, such as population, unemployment, and poverty rate. This paper compares and visualizes the crime data for four different cities in the USA, namely Chicago, Baltimore, Dallas, and Denton. We assess areas that are significantly affected based on zip codes and variations in crime categories. As the crime rates have significantly changed both upward and downward throughout time, these changes are compared to their external causes such as population, unemployment, and poverty. The results show crime frequency and distribution across four different cities and supply valuable information about the complex relationship between social factors and criminal behavior. These results and outcomes will help the police department and law enforcement organizations better understand crime issues, map crime incidents onto a geographical map, and supply insight into factors affecting crime that will help them deploy resources and help in their decision-making process.

    This study aims to find how crime rates in Maryland are connected to different socioeconomic elements. This study is focused on understanding how crime rates link up with factors like unemployment, household income levels, racial backgrounds, and the level of education people have. A quantitative analysis of state-level crime data from 2010 to 2020 was used; the study employs a comprehensive range of methods. Conducted a detailed picture through descriptive analysis, then reshaped data using log and square root transformations, and tested hypotheses with a t-test. The paper further examines the relationships between variables through a correlation matrix before applying ordinary least squares regression to predict outcomes. It has been discovered that areas facing more significant economic challenges seen through higher Unemployment rates and diminished earnings frequently show an uptick in crime. The examination highlights a strong link between unemployment and criminal behavior, especially in counties where families consistently earn less. Research highlights how vital education is by showing that when people achieve higher levels of education, they tend to commit fewer crimes. The study illuminates the intricate interplay between economic factors and criminal activities, offering invaluable insights for law enforcement agencies and policymakers. These insights can guide the development of effective strategies to combat crime; ultimately, the research deepens our understanding of how economic fluctuations significantly influence crime rates in Maryland.

    In the throes of an intractable overdose crisis, U.S. pharmacists have begun to engage in an unexpected practice—policing patients. Contemporary sociological theory does not explain why. Theories of professions and frontline work suggest professions closely guard jurisdictions and make decisions based on the logics of their own fields. Theories of criminal-legal expansion show that non-enforcement fields have become reoriented around crime over the past several decades, but past work largely focuses on macro-level consequences. This article uses the case of pharmacists and opioids to develop a micro-level theory of professional field reorientation around crime, the Trojan Horse Framework. Drawing on 118 longitudinal and cross-sectional interviews with pharmacists in six states, I reveal how the use of prescription drug monitoring programs (PDMPs)—surveillance technology designed for law enforcement but implemented in healthcare—in conjunction with a set of field conditions motivates pharmacists to police patients. PDMPs serve as Trojan horse technologies as their use shifts pharmacists’ routines, relationships with other professionals, and constructions of their professional roles. As a result, pharmacists route patients out of the healthcare system and leave them vulnerable to the criminal-legal system. The article concludes with policy recommendations and a discussion of future applications of the Trojan Horse Framework.

    Data visualization gives a visual context through maps or graphs and makes it easier for the human mind to identify trends, patterns, and outliers within large data sets. The understanding of patterns and location of crime through data visualization and data mining techniques approaches is a very useful tool which can help and support police forces. Identification of crime characteristics and types are the first step for developing further analysis. This paper describes the development of data visualization tool using Unity 3D and Maptitude GIS for visualization of Baltimore COVID-19 and crime data. This effort aims to determine parameters that influence the vulnerability of African Americans to COVID-19 during the pandemic. The study has found that the factors shown to be influential in a person’s susceptibility include neighborhood and physical environment, housing, occupation, education, income, and wealth gaps. The data collected from Baltimore incident reports and findings shared by Maryland SOA office shows that crime has increased and decreased in different areas during the time of COVID pandemic.

    Indoor navigation in complex building environments poses significant challenges, particularly for individuals who are unfamiliar with their surroundings. Mixed reality (MR) technologies have emerged as a promising solution to enhance situational awareness and facilitate navigation within indoor spaces. However, there is a lack of spatial data for indoor environments, including outdated floor plans and limited real-time operational data. This paper presents the development of a mixed-reality application for indoor building navigation and evacuation. The application uses feature extraction for location sensing and situational awareness to provide accurate and reliable navigation in any indoor environment using Microsoft HoloLens. The application can track the user's position and orientation and give the user-specific information on how to evacuate the building. This information is then used to generate navigation instructions for the user. We demonstrate how this mixed reality HoloLens application can provide spatially contextualized 3D visualizations that promote spatial knowledge acquisition and situational awareness. These 3D visualizations are developed as an emergency evacuation and navigation tool to aid the building occupants in safe and quick evacuation. Experimental results demonstrate the effectiveness of the application, providing 3D visualizations of multilevel spaces and aiding individuals in understanding their position and evacuation path during emergencies. We believe that adopting mixed reality technologies, such as the HoloLens, can greatly enhance individuals' ability to navigate large-scale environments during emergencies by promoting spatial knowledge acquisition and supporting cognitive mapping.
