Abstract:

Society generates more and more data every day, and with competent ways to visualize it, we can learn new things about the world we live in. While traditional visualizations try to stay clear of 3D graphs because they are hard for a user to process without proper depth cues, VR technology allows us to better perceive 3D structures, but what happens to our overview of the data when we perceive and interact with it in 3D? 6 participants were subject to a 3D VR visualization of customer data with filtering possibilities, where they were to perform a series of short tasks as well as a more open-en

Abstract:

<p> Information visualization offers a unique method to assist users in understanding large quantities of data, such as that which is found in social media. The recent surge in the use of social media platforms, the abundance of data generated, and the implications about what this data means has made it increasingly necessary to provide feedback to these users about what they and others are presenting online. Thus, it is critical for these individuals to access this information and gain some level of visual understanding regarding their own identities or that of a particular group. This disser

Abstract:

As we are heading into immersive virtual reality environments for different purposes - entertainment being the most prominent lately - we should consider how we design interactive information visualizations for VR. Is it wise to hold onto the same elements of interaction with which we are familiar from contemporary web-based interfaces? The study explores this question along with others, to explore ways to conduct familiar filtering operations known from web environments, in VR. An interactive information visualization application in VR was created to evaluate two web-inspired interaction meth

Minimally invasive surgeries (MIS) are fundamentally constrained by image quality,access to the operative field, and the visualization environment on which thesurgeon relies for real-time information. Although invasive access benefits the patient,it also leads to more challenging procedures, which require better skills andtraining. Endoscopic surgeries rely heavily on 2D interfaces, introducing additionalchallenges due to the loss of depth perception, the lack of 3-Dimensional imaging,and the reduction of degrees of freedom.By using state-of-the-art technology within a distributed computationa

This thesis addresses the question of the design, production and use of information graphics in health technology assessment (HTA). Drawing on previous research in both information design and health policy, it describes a comprehensive design process for creating new visual presentations that can inform health policy-makers. The thesis begins by introducing, and functionally defining the terms ‘information graphics’ and ‘health technology assessment’ in Chapter 1. It then offers a methodological discussion of how research can be performed at the intersection between these two diverse fields. T

I assert that the final forms of EV artworks are not necessarily dependent on technology, and can differ in terms of media used, in that they can be sculptural, video-based, or static two-dimensional forms that communicate interpreted environmental information. There are two main categories of EV: one that is predominantly screen-based

Abstract:

Research in automatic control has enabled trucks to use adaptive cruise control to drive very close to each other and form platoons. This reduces drag and improves efficiency by lowering fuel consumption. A central challenge to understanding the formation of these platoons is that not all trucks are emerging from the same origin or reaching the same destination; they only share parts of their joint trip. This study uses participatory design methodologies to create a design for an interactive visualization system to enable researchers to study the formation of platoons in simulated scenarios. T

Abstract:

Cyber insider threat is one of the most difficult risks to mitigate in organizations. However, innovative validated visualizations for cyber analysts to better decipher and react to detected anomalies has not been reported in literature or in industry. Attacks caused by malicious insiders can cause millions of dollars in losses to an organization. Though there have been advances in Intrusion Detection Systems (IDSs) over the last three decades, traditional IDSs do not specialize in anomaly identification caused by insiders. There is also a profuse amount of data being presented to cyber analys

Abstract:

With exponential growth on a daily basis, there is potentially valuable information hidden in complex electronic medical records (EMR) systems. In this thesis, several efficient data mining algorithms were explored to discover hidden knowledge in insurance claims data. The first aim was to cluster three levels of information overload(IO) groups among chronic rheumatic disease (CRD) patient groups based on their clinical events extracted from insurance claims data. The second aim was to discover hidden patterns using three renowned pattern mining algorithms: Apriori, frequent pattern growth(FP-

Abstract:

Information visualization dashboards are a widely used supportive tool in decision making. These tools can be difficult to create and utilize especially for the novice user. There is an extensive collection of company related data for decision making, resulting in a need of assistive tools. Prototypes were developed to research and identify design guidelines how to support fund managers in their decision making. This was carried out as a qualitative study involving 7 experts in fund management. The results provide insights and guidelines in decision supportive design for dashboards. The result

Information technology has played several important roles in group decision making, such as communication support and decision support. Little is known about how information technology can be used to persuade members of a group to reach a consensus. In this dissertation, I aim to address the issues that are related to the role of visual representation technology (VRT) for persuasion in a forecasting context. VRTs are not traditional graphical representation technologies. VRTs can select, transform, and present data in a rich visual format that facilitates exploration, comprehension, and sense-
