      For museum curators it is imperative to learn, analyze, and understand the behavior patterns of the visitors in their museum. Recent developments in the field of indoor positioning systems make the acquisition and availability ...
    • Metro Transit-Centric Visualization for City Tour Planning 

      Claudio, Pio; Yoon, Sung-Eui (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      In general, city trip planning consists of two main steps: knowing Points-Of-Interest (POIs), and then planning a tour route from the current point to next preferred POIs. We mainly consider the metro for traveling around ...
    • A Gaze-enabled Graph Visualization to Improve Graph Reading Tasks 

      Okoe, Mershack; Alam, Sayeed Safayet; Jianu, Radu (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Performing typical network tasks such as node scanning and path tracing can be difficult in large and dense graphs. To alleviate this problem we use eye-tracking as an interactive input to detect tasks that users intend ...
    • Visual Multiplexing 

      Chen, Min; Walton, Simon; Berger, Kai; Thiyagalingam, Jeyan; Duffy, Brian; Fang, Hui; Holloway, Cameron; Trefethen, Anne E. (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      The majority of display devices used in visualization are 2D displays. Inevitably, it is often necessary to overlay one piece of visual information on top of another, especially in applications such as multi-field visualization ...
    • Methods for Compensating Contrast Effects in Information Visualization 

      Mittelstädt, Sebastian; Stoffel, Andreas; Keim, Daniel A. (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Color, as one of the most effective visual variables, is used in many techniques to encode and group data points according to different features. Relations between features and groups appear as visual patterns in the ...
    • ConVis: A Visual Text Analytic System for Exploring Blog Conversations 

      Hoque, Enamul; Carenini, Giuseppe (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Today it is quite common for people to exchange hundreds of comments in online conversations (e.g., blogs). Often, it can be very difficult to analyze and gain insights from such long conversations. To address this problem, ...
