    • Abbreviating Text Labels on Demand 

      Shimabukuro, Mariana; Collins, Christopher (IEEE, 2017-10)
      Long text labels is a known challenge in information visualizations.There are some techniques used in order to solve this problem like setting a very small font size. On the other hand, sometimes the font size is so small ...
    • An adaptive crowdsourced investigation of word abbreviation techniques for text visualizations 

      Shimabukuro, Mariana Akemi (2017-04-01)
      A known problem in information visualization labeling is when the text is too long to fit in the label space. There are some common known techniques used in order to solve this problem like setting a very small font size. ...
    • Approaching Humanities Questions Using Slow Visual Search Interfaces 

      Bradley, Adam James; Sawal, Victor; Collins, Christopher (2021-06-01)
      In this paper we discuss a visual search system that was designed and implemented for humanities scholars to ask questions of large document corpora. The system allows searches to be specified through traditional search, ...
    • Augmenting free-form annotations with digital metadata for close reading of poetry 

      Mehta, Hrim (2015-12-01)
      Many people, literary critics in particular, practice close reading, making annotations by hand while performing a detailed analysis of a text. Current digital tools for literary criticism,however, have many limitations ...

    • Critical InfoVis: Exploring the Politics of Visualization 

      Dörk, Marian; Feng, Patrick; Collins, Christopher; Carpendale, Sheelagh (ACM, 2013-04-27)
      As information visualization is increasingly used to raise awareness about social issues, difficult questions arise about the power of visualization. So far the research community has not given sufficient thought to how ...
    • Design by Immersion: A Transdisciplinary Approach to Problem-Driven Visualizations 

      Hall, Kyle Wm.; Bradley, Adam J.; Hinrichs, Uta; Huron, Samuel; Wood, Jo; Collins, Christopher; Carpendale, Sheelagh (IEEE, 2019-08-26)
      While previous work exists on how to conduct and disseminate insights from problem-driven visualization projects and design studies, the literature does not address how to accomplish these goals in transdisciplinary teams ...
    • Exploring entities in text with descriptive non-photorealistic rendering 

      Chang, Meng-Wei (2012-12-01)
      We present a novel approach to text visualization called descriptive non-photorealistic rendering which exploits the inherent spatial and abstract dimensions in text documents to integrate 3D non-photorealistic rendering ...
    • Exploring Entities in Text with Descriptive Non-photorealistic Rendering 

      Chang, Meng-Wei; Collins, Christopher (IEEE, 2013-03)
      We present a novel approach to text visualization called descriptive non-photorealistic rendering which exploits the inherent spatial and abstract dimensions in text documents to integrate 3D non-photorealistic rendering ...
    • Gloss positioning for a gaze aware L2 reading aid 

      Zhao, Zixin (2023-08-01)
      An important aspect of language learning is reading texts written in the learner’s second language (L2). However, reading can be a daunting task for language learners, as text may contain a large amount of unknown vocabulary. ...
    • Implicit gaze interaction for information visualization 

      Wang, Feiyang (2021-08-01)
      This thesis presents a novel marker-free method for identifying screens of interest when using head-mounted eye-tracking for visualization in cluttered and multi-screen environments. The presented approach offers a solution ...
    • An investigation of semantic patterns in passwords 

      Veras Guimaraes, Rafael (2013-08-01)
      The advent of large password leaks in recent years has exposed the security problems of passwords and enabled deeper empirical investigation of password patterns. Researchers have only touched the surface of patterns in ...
    • Lexichrome: Text Construction and Lexical Discovery with Word-Color Associations Using Interactive Visualization 

      Kim, Chris K; Collins, Christopher; Hinrichs, Uta; Mohammad, Saif M (ACM, 2020-07-03)
      Based on word-color associations from a comprehensive, crowdsourced lexicon, we present Lexichrome: a web application that explores the popular perception of relationships between English words and eleven basic color terms ...
    • Magic Pen: automatic pen-mode switching for document annotation 

      Desousa, Kevin A. (2022-08-01)
      Traditional digital pen interfaces use menu buttons to change pen modes, resulting in time and cognitive load spent on round-trips and potential errors from tapping small mode selection buttons. This thesis presents Magic ...
    • Managing developer interruption 

      Perez Dias, Gabrielle Cristina (2018-12-01)
      The high frequency of interruptions during cognitively-intense activities can be annoying and detrimental to deadline-driven work, such as software development. When developers are interrupted they not only lose productivity ...
