We followed a structured, iterative design process including requirement analysis and multiple design and prototyping iterations in close cooperation with journalists. To validate our concept and prototype, a workshop series and two diary studies were conducted with journalists.

With the increasing simultaneous usage of several different devices like smartphone, tablet and connected TV new approaches for media consumption are conceivable. One specific instance is a Second Screen scenario where users complement information from unidirectional media broadcasts (i.e. TV) with additional facts from a secondary Internet connected source (e.g. smartphone or tablet). However Second Screen applications are still in its infancy and very little is known on how to properly design them. The focus in the thesis will be on the role of data visualizations and how it can be used in Second Screen application for both sides: for the viewer, allowing interactive access to additional, visual, and personalized information that is not included in the broadcast TV content; but also for the TV stations, in order to get richer data about their audience by providing a direct backchannel. By answering the research questions the complete process of designing and developing interactive data visualization in the context of Second Screen applications for mobile touch devices will be investigated. In addition to several state-of-the-art reports a tested framework, which includes all relevant parts of a Second Screen application (e.g. content creation, synchronization, different types of visualization), and guidelines for designing and developing mobile data visualization for Second Screen applications, which are synchronized with the broadcast, will be developed.}, booktitle = {Doctoral {Consortium} on {Computer} {Vision}, {Imaging} and {Computer} {Graphics} {Theory} and {Applications} ({DCVISIGRAPP} 2015)}, publisher = {SCITEPRESS Digital Library}, author = {Blumenstein, Kerstin}, year = {2015}, note = {Projekt: KAVA-Time Projekt: VALID}, keywords = {2015, AV, Department Medien und Digitale Technologien, Department Technologie, Forschungsgruppe Media Computing, Institut für Creative Media Technologies, Publikationstyp Präsentation, Publikationstyp Schriftpublikation, mobile computing, peer-reviewed, visualization, ⛔ No DOI found}, } @article{dahnert_looking_2019, title = {Looking beyond the horizon: {Evaluation} of four compact visualization techniques for time series in a spatial context}, shorttitle = {Looking beyond the horizon}, url = {http://arxiv.org/abs/1906.07377}, abstract = {Visualizing time series in a dense spatial context such as a geographical map is a challenging task, which requires careful balance between the amount of depicted data and perceptual precision. Horizon graphs are a well-known technique for compactly representing time series data. They provide fine details while simultaneously giving an overview of the data where extrema are emphasized. Horizon graphs compress the vertical resolution of the individual line graphs, but they do not affect the horizontal resolution. We present two variations of a new visualization technique called collapsed horizon graphs which extend the idea of horizon graphs to two dimensions. Our main contribution is a quantitative evaluation that experimentally compares four visualization techniques with high visual information resolution (compact boxplots, horizon graphs, collapsed horizon graphs, and braided collapsed horizon graphs). The experiment investigates the performance of these techniques across tasks addressing both individual graphs as well as groups of adjacent graphs. Compact boxplots consistently provide good results for all tasks, horizon graphs excel, for instance, in maximum tasks but underperform in trend detection. Collapsed horizon graphs shine in certain tasks in which an increased horizontal resolution is beneficial. Moreover, our results indicate that the visual complexity of the techniques highly affects users' confidence and perceived task difficulty.}, urldate = {2019-06-19}, journal = {arXiv:1906.07377 [cs]}, author = {Dahnert, Manuel and Rind, Alexander and Aigner, Wolfgang and Kehrer, Johannes}, year = {2019}, note = {Projekt: KAVA-Time Projekt: VisOnFire Projekt: VALID}, keywords = {FH SP Data Analytics \& Visual Computing, Forschungsgruppe Media Computing, Institut für Creative Media Technologies, Visual Computing, Wiss.
