    • A Crowdsourced Approach to Colormap Assessment 

      Turton, Terece L.; Ware, Colin; Samsel, Francesca; Rogers, David H. (The Eurographics Association, 2017)
      Despite continual research and discussion on the perceptual effects of color in scientific visualization, psychophysical testing is often limited. In-person lab studies can be expensive and time-consuming while results can ...

    • Development of a VR Planning Model of a River Lock for Risk Assessment in the Construction and Machinery Industry 

      Nickel, Peter; Proeger, Eugen; Kergel, Rolf; Lungfiel, Andy (The Eurographics Association, 2014)
      There is a growing interest in prospective risk assessments to enable design improvements early in machinery development. Though simulation-based methods such as virtual reality (VR) may provide assistance for risk assessment, ...

    • ETK: An Evaluation Toolkit for Visualization User Studies 

      Turton, Terece L.; Berres, Anne S.; Rogers, David H.; Ahrens, James (The Eurographics Association, 2017)
      This paper describes the design and features of the Evaluation Toolkit (ETK), a set of JavaScript/HTML/CSS modules leveraging the Qualtrics JavaScript API that can be used to automate image-based perceptual user evaluation ...

    • Evaluating the Perceptual Uniformity of Color Sequences for Feature Discrimination 

      Ware, Colin; Turton, Terece L.; Samsel, Francesca; Bujack, Roxana; Rogers, David H. (The Eurographics Association, 2017)
      Probably the most common method for visualizing univariate data maps is through pseudocoloring and one of the most commonly cited requirements of a good colormap is that it be perceptually uniform. This means that differences ...

    • Gaze-Based Biometric Authentication: Hand-Eye Coordination Patterns as a Biometric Trait 

      Çig, Çagla; Sezgin, Tevfik Metin (The Eurographics Association, 2016)
      We propose a biometric authentication system for pointer-based systems including, but not limited to, increasingly prominent pen-based mobile devices. To unlock a mobile device equipped with our biometric authentication ...

    • Intuitive Colormaps for Environmental Visualization 

      Samsel, Francesca; Turton, Terece L.; Wolfram, Philip; Bujack, Roxana (The Eurographics Association, 2017)
      Visualizations benefit from the use of intuitive colors, enabling an observer to make use of more automatic, subconscious channels. In this paper, we apply the concept of intuitive color association to the generation of ...

    • Perceiving Complex Causation Through Interaction 

      Ware, Colin (ACM, 2013)
      When we interact with a touch screen computational device we have the strong subjective impression that we are directly causing changes that occur on the screen. For example, sliding a finger on a screen causes scrolling ...

    • Real-Time Activity Prediction: A Gaze-Based Approach for Early Recognition of Pen-Based Interaction Tasks 

      Çıg, Çagla; Sezgin, Tevfik Metin (The Eurographics Association, 2015)
      Recently there has been a growing interest in sketch recognition technologies for facilitating human-computer interaction. Existing sketch recognition studies mainly focus on recognizing pre-defined symbols and gestures. ...
