      El-Assady, Mennatallah; Sevastjanova, Rita; Sperrle, Fabian; Keim, Daniel; Collins, Christopher (IEEE, 2017-08-29)
      Topic modeling algorithms are widely used to analyze the thematic composition of text corpora but remain difficult to interpret and adjust. Addressing these limitations, we present a modular visual analytics framework, ...
    • Rational design of a material for rapid colorimetric Fe2+ detection 

      Zenkina, O.V; Laschuk, N. O.; Ebralidze, I. I.; Quaranta, S.; Kerr, S.; Egan, J. G.; Gillis, S.; Gaspari, F.; Latini, A. (Elsevier, 2016-10-05)
      We report on the rational design of a novel TiO2 based screen-printed material suitable for sensitive and selective detection of iron ions in water. This includes the synthesis and characterization of large mesoporous TiO2 ...
    • The Role of Interactive Visualization in Fostering Trust in AI 

      Beauxis-Aussalet, Emma; Behrisch, Michael; Borgo, Rita; Chau, Duen Horng; Collins, Christopher; Ebert, David; El-Assady, Mennatallah; Endert, Alex; Keim, Daniel A.; Kohlhammer, Jörn; Oelke, Daniela; Peltonen, Jaakko; Riveiro, Maria; Schreck, Tobias; Strobelt, Hendrik; van Wijk, Jarke J. (IEEE, 2021-12-10)
      The increasing use of artificial intelligence (AI) technologies across application domains has prompted our society to pay closer attention to AI's trustworthiness, fairness, interpretability, and accountability. In order ...
    • Saliency Deficit and Motion Outlier Detection in Animated Scatterplots 

      Veras, Rafael; Collins, Christopher (Association for Computing Machinery, 2019-05-04)
      We report the results of a crowdsourced experiment that measured the accuracy of motion outlier detection in multivariate, animated scatterplots. The targets were outliers either in speed or direction of motion, and were ...
    • TandemTable: Supporting Conversations and Language Learning Using a Multi-Touch Digital Table 

      Paluka, Erik; Collins, Christopher (Association for Computing Machinery, 2015-06-03)
      We present TandemTable, a multi-touch tabletop system designed to break down communication barriers between partners, with a special focus on supporting those who are learning languages. The design was guided by a grounding ...
    • Textension: Digitally Augmenting Document Spaces in Analog Texts 

      Bradley, Adam James; Sawal, Victor; Carpendale, Sheelagh; Collins, Christopher (DHQ, 2019)
      In this paper, we present a system that automatically adds visualizations and natural language processing applications to analog texts, using any web-based device with a camera. After taking a picture of a particular page ...
    • Tied In Knots: A Case Study on Anthropographic Data Visualization About Sexual Harassment in the Academy 

      Elli, Tommaso; Bradley, Adam; Collins, Christopher; Hinrichs, Uta; Hills, Zachary; Kelsky, Karen (IEEE, 2020-10-30)
