	abstract = {In information visualization, interaction mechanisms are an essential factor to the success of visualization. They should be easy to use and useful for filtering, exploring, and analyzing the data visualized. Usually, direct manipulation on the visualizations is the most important aspect that researches consider. However, users still tend to use controls (widgets) for some interaction, especially, when manipulating (e.g., filtering) the data. During our work with users on the visual representation of safety analysis results, we found limitations in the interaction capabilities of sliders. In order to overcome these limitations, we introduce our Range-Selection-and-Filtering RSF slider, which enables users to work more efficiently when selecting relevant data from large data sets compared to conventional slider designs by enhancing the ease of use and increasing its usefulness. Additionally, we applied this slider to different application domains and evaluated it.},

	abstract = {Fast changing urban systems pose huge challenges for planners and governments. One major challenge is to provide optimized facilities systems fulfilling all the basic citizen needs such as food, education, security, and health. To provide these, the deficit of the complete system needs to be analyzed and quantified. An additional, important problem is the quality of the underlying data influencing the analysis. Often, the data is, e.g., incomplete, not accurate, or not reliable. The goal of this paper is to support the analysis of the deficit for the facilities system of Bogot{\'a} by taking into account data quality issues. Our contributions are: the inclusion of data quality in the urban planning process, the design of a novel visualization technique to represent data quality, the implementation of an application to support the analysis of the facilities system, and a case study with experts assessing the usability and usefulness of the application. As a conclusion, the experts find the application useful for the analysis tasks and the inclusion of data quality features important and comprehensible.},

	abstract = {Tensors are of great interest to many applications in engineering and in medical imaging, but a proper analysis and visualization remains challenging. Physics-based visualization of tensor fields has proven to show the main features of symmetric second-order tensor fields, while still displaying the most important information of the data, namely the main directions in medical diffusion tensor data using texture and additional attributes using color-coding, in a continuous representation. Nevertheless, its application and usability remains limited due to its computational expensive and sensitive nature. We introduce a novel approach to compute a fabric-like texture pattern from tensor fields motivated by image-space line integral convolution (LIC). Although, our approach can be applied to arbitrary, non-selfintersecting surfaces, we are focusing on special surfaces following neural fibers in the brain. We employ a multi-pass rendering approach whose main focus lies on regaining three-dimensionality of the data under user interaction as well as being able to have a seamless transition between local and global structures including a proper visualization of degenerated points.},
