Available in PDF, EPUB and Kindle. Book excerpt: In the era of big data, healthcare practitioners are increasingly generating and analyzing data. The huge volume of data provides opportunities for evidence based medicine to answer research and practical questions, and for individuals to make better informed, smarter decision. Yet, making sense of massive healthcare datasets remains a fundamental challenge. In order to make inferences on the data, an effective visual representations of the data is needed. We propose visualization as a means to derive inferences on healthcare data. Design of visual analytics tools, therefore, becomes important in the healthcare domain. Healthcare is a broad area involving users with high variation in roles, expertise, and background. The diverse characteristics of users and their shifting contexts makes it a challenge to process and to present healthcare data in appropriate visual representations that is directly relevant to the analytics tasks.We advocate using the User-Centered Design (UCD) approach in designing and developing visual analytics tools in healthcare. The core research question is how a user centered approach should be adopted in designing visual analytics tools. We address the question by bringing the user centered design process and visual analytics process together, and by applying interdisciplinary methods, such as data mining, information visualization and network analytics. In particular, the dissertation looks to three studies in the healthcare domain where practitioners follow UCD to design visual analytics in healthcare domain. We emphasis the role of user involvement in the entire iterative design lifecycle. The users spanning these studies include patients, physicians, nanomaterial scientists, biomedical professionals, and healthcare policy makers. The three studies are:1. Developing a visual web-based tool called VisOSA to interpret and explore medical records of patients with sleep apnea. For physicians, the ClinicView provides an interactive tool to have an overview of the entire medical record of patients including anomalies, and therefore help with generating research hypothesis. For patients, the PatientView allows the lay individual - without any medical background - to understand their health conditions under treatment at a glance. We also defined medical dashboard in this study. We conducted a supporting quantitative behavioral research to examine the effect of multiple monitors on people's performance. Results suggested that the medical dashboard needs to be arranged as that the most important information is in a single screen. 2. Studying the nanomaterial environmental impact (NEI) is a critical task in nano-health and safety. The information visualization module for NEIMiner is a visual analytic tool that can efficiently query and present large-scale bibliography meta-data, NEI characterizations and nanomaterial toxicity. It supports nanomaterial scientists and analysts to explore the concepts and relationships in studying nanomaterial toxicity and its impact on health. 3. Translating research findings into effective clinical care is another overwhelming task. VATS is a scalable multi-scale visual analytical tool for advancing translational sciences. The system integrates the data of National Center for Advancing Translational Science (NCATS) funded projects and publications from NIH Research Portfolio Online Reporting Tools (RePORTER) and PubMed, and helps healthcare policy makers to understand the big picture of translational science and to evaluate the impact of NCATS funded projects through publicly available data sources.Through these studies, we discuss how innovative visual analytics techniques and capabilities with help users understand and act on various type of data. The results and applications demonstrate what purposes visualizations are used for each problem, how the design and development team make decisions around datasets, and the different visual representations healthcare practitioners use to explore and gain insight of data. The research contributions are (1) a joint model of UCD and visual analytics process that overcomes the design challenges, (2) a justification of how existing data mining and visualization techniques can be usefully combined to support analytics task in healthcare, (3) the approaches to integrate and enrich the dataset, and turn the data into reliable and provable information, (4) the visual encoding and interaction mechanisms to present complex information, (5) three visual analytics system built are beneficial to healthcare community and society. The design guidelines and recommendations generated from these studies are applicable to various domains. We hope this work inspire more innovations and conversations at the intersection of user centered design and visual analytics.

Download or read book User Centered Evaluation of Visual Analytics written by Jean Scholtz and published by Morgan & Claypool Publishers. This book was released on 2017-10-06 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: Visual analytics has come a long way since its inception in 2005. The amount of data in the world today has increased significantly and experts in many domains are struggling to make sense of their data. Visual analytics is helping them conduct their analyses. While software developers have worked for many years to develop software that helps users do their tasks, this task is becoming more and more onerous, as understanding the needs and data used by expert users requires more than some simple usability testing during the development process. The need for a user centered evaluation process was envisioned in Illuminating the Path, the seminal work on visual analytics by James Thomas and Kristin Cook in 2005. We have learned over the intervening years that not only will user-centered evaluation help software developers to turn out products that have more utility, the evaluation efforts can also help point out the direction for future research efforts. This book describes the efforts that go into analysis, including critical thinking, sensemaking, and various analytics techniques learned from the intelligence community. Support for these components is needed in order to provide the most utility for the expert users. There are a good number of techniques for evaluating software that has been developed within the human-computer interaction (HCI) community. While some of these techniques can be used as is, others require modifications. These too are described in the book. An essential point to stress is that the users of the domains for which visual analytics tools are being designed need to be involved in the process. The work they do and the obstacles in their current processes need to be understood in order to determine both the types of evaluations needed and the metrics to use in these evaluations. At this point in time, very few published efforts describe more than informal evaluations. The purpose of this book is to help readers understand the need for more user-centered evaluations to drive both better-designed products and to define areas for future research. Hopefully readers will view this work as an exciting and creative effort and will join the community involved in these efforts.

Download or read book The Patient Revolution written by Krisa Tailor and published by John Wiley & Sons. This book was released on 2015-12-17 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: In The Patient Revolution, author Krisa Tailor—a noted expert in health care innovation and management—explores, through the lens of design thinking, how information technology will take health care into the experience economy. In the experience economy, patients will shift to being empowered consumers who are active participants in their own care. Tailor explores this shift by creating a vision for a newly designed health care system that's focused on both sickness and wellness, and is driven by data and analytics. The new system seamlessly integrates health into our daily lives, and delivers care so uniquely personalized that no two people are provided identical treatments. Connected through data, everyone across the health care ecosystem, including clinicians, insurers, and researchers, will be able to meet individuals wherever they are in their health journey to reach the ultimate goal of keeping people healthy. The patient revolution has just begun and an exciting journey awaits us. Praise for the patient revolution "A full 50% of the US population has at least one chronic disease that requires ongoing monitoring and treatment. Our current health care system is woefully inadequate in providing these individuals with the treatment and support they need. This disparity can only be addressed through empowering patients to better care for themselves and giving providers better tools to care for their patients. Both of those solutions will require the development and application of novel technologies. In Krisa Tailor's book The Patient Revolution, a blueprint is articulated for how this could be achieved, culminating in a vision for a learning health system within 10 years." —Ricky Bloomfield, MD, Director, Mobile Technology Strategy; Assistant Professor, Duke Medicine "In The Patient Revolution, Krisa Tailor astutely points out that 80% of health is impacted by factors outside of the health care system. Amazon unfortunately knows more about our patients than we do. The prescriptive analytics she describes will allow health care providers to use big data to optimize interventions at the level of the individual patient. The use of analytics will allow providers to improve quality, shape care coordination, and contain costs. Advanced analytics will lead to personalized care and ultimately empowered patients!" —Linda Butler, MD, Vice President of Medical Affairs/Chief Medical Officer/Chief Medical Information Officer, Rex Healthcare "The Patient Revolution provides a practical roadmap on how the industry can capture value by making health and care more personalized, anticipatory, and intuitive to patient needs." —Ash Damle, CEO, Lumiata "Excellent read. For me, health care represents a unique economy—one focused on technology, but requiring a deep understanding of humanity. Ms. Tailor begins the exploration of how we provide care via the concepts of design thinking, asking how we might redesign care with an eye toward changing the experience. She does an excellent job deconstructing this from the patient experience. I look forward to a hopeful follow-up directed at changing the provider culture." —Alan Pitt, MD, Chief Medical Officer, Avizia "Whether you're a health care provider looking to gain an understanding of the health care landscape, a health data scientist, or a seasoned business pro, you'll come away with a deeper, nuanced understanding of today's evolving health care system with this book. Krisa Tailor ties together—in a comprehensive, unique way—the worlds of health care administration, clinical practice, design thinking, and business strategy and innovation." —Steven Chan, MD, MBA, University of California, Davis

Download or read book It s About Time written by Kahin Akram Hassan and published by Linköping University Electronic Press. This book was released on 2021-02-26 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary goal for collecting and analyzing temporal data differs between individuals and their domain of expertise e.g., forecasting might be the goal in meteorology, anomaly detection might be the goal in finance. While the goal differs, one common denominator is the need for exploratory analysis of the temporal data, as this can aid the search for useful information. However, as temporal data can be challenging to understand and visualize, selecting appropriate visual representations for the domain and data at hand becomes a challenge. Moreover, many visual representations can show a single variable that changes over time, displaying multiple variables in a clear and easily accessible way is much harder, and inference-making and pattern recognition often require visualization of multiple variables. Additionally, as visualization aims to gain insight, it becomes crucial to investigate whether the representations used help users gain this insight. Furthermore, to create effective and efficient visual analysis tools, it is vital to understand the structure of the data, how this data can be represented, and have a clear understanding of the user needs. Developing useful visual representations can be challenging, but through close collaboration and involvement of end-users in the entire process, useful results can be accomplished. This thesis aims to investigate the usability of different visual representations for different types of multivariate temporal data, users, and tasks. Five user studies have been conducted to investigate different representation spaces, layouts, and interaction methods for investigating representations’ ability to facilitate users when analyzing and exploring such temporal datasets. The first study investigated and evaluated the experience of different radial design ideas for finding and comparison tasks when presenting hourly data based on an analog clock metaphor. The second study investigated 2D and 3D parallel coordinates for pattern finding. In the third study, the usability of three linear visual representations for presenting indoor climate data was investigated with domain experts. The fourth study continued on the third study and developed and evaluated a visual analytics tool with different visual representations and interaction techniques with domain experts. Finally, in the fifth study, another visual analytics tool presenting visual representations of temporal data was developed and evaluated with domain experts working and conducting experiments in Antarctica. The research conducted within the scope of this thesis concludes that it is vital to understand the characteristics of the temporal data and user needs for selecting the optimal representations. Without this knowledge, it becomes much harder to choose visual representations to help users gain insight from the data. It is also crucial to evaluate the perception and usability of the chosen visual representations.

Download or read book Design of Visualizations for Human Information Interaction written by Kamran Sedig and published by Morgan & Claypool Publishers. This book was released on 2016-04-18 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interest in visualization design has increased in recent years. While there is a large body of existing work from which visualization designers can draw, much of the past research has focused on developing new tools and techniques that are aimed at specific contexts. Less focus has been placed on developing holistic frameworks, models, and theories that can guide visualization design at a general level—a level that transcends domains, data types, users, and other contextual factors. In addition, little emphasis has been placed on the thinking processes of designers, including the concepts that designers use, while they are engaged in a visualization design activity. In this book we present a general, holistic framework that is intended to support visualization design for human-information interaction. The framework is composed of a number of conceptual elements that can aid in design thinking. The core of the framework is a pattern language—consisting of a set of 14 basic, abstract patterns—and a simple syntax for describing how the patterns are blended. We also present a design process, made up of four main stages, for creating static or interactive visualizations. The 4-stage design process places the patterns at the core of designers’ thinking, and employs a number of conceptual tools that help designers think systematically about creating visualizations based on the information they intend to represent. Although the framework can be used to design static visualizations for simple tasks, its real utility can be found when designing visualizations with interactive possibilities in mind—in other words, designing to support a human-information interactive discourse. This is especially true in contexts where interactive visualizations need to support complex tasks and activities involving large and complex information spaces. The framework is intended to be general and can thus be used to design visualizations for diverse domains, users, information spaces, and tasks in different fields such as business intelligence, health and medical informatics, digital libraries, journalism, education, scientific discovery, and others. Drawing from research in multiple disciplines, we introduce novel concepts and terms that can positively contribute to visualization design practice and education, and will hopefully stimulate further research in this area.
