      Several studies have indicated the need for personalizing gamified systems to users' personalities. However, mapping user personality onto design elements is difficult. Hexad is a gamification user types model that attempts ...
    • Geo-Phisher: The Design and Evaluation of Information Visualizations about Internet Phishing Trends 

      Zhang-Kennedy, Leah; Fares, Elias; Chiasson, Sonia; Biddle, Robert (IEEE, 2016-06)

    • Heuristic Evaluation for Gameful Design 

      Fortes Tondello, Gustavo; Kappen, Dennis; Mekler, Elisa; Ganaba, Marim; Nacke, Lennart (Association for Computing Machinery, 2016-10-16)
      Despite the emergence of many gameful design methods in the literature, there is a lack of evaluation methods specific to gameful design. To address this gap, we present a new set of guidelines for heuristic evaluation of ...
    • Investigating the Impact of Cooperative Communication Mechanics on Player Performance in Portal 2 

      Vaddi, Deepika; Toups, Zachary; Dolgov, Igor; Wehbe, Rina Renee; Nacke, Lennart (Canadian Human-Computer Communications Society, 2016-06)
      Cooperative communication mechanics, such as avatar gestures or in-game visual pointers, enable player collaboration directly through gameplay. We currently lack a deeper understanding of how players use cooperative ...
    • Lightweight Games User Research for Indies and Non-Profit Organizations

    • Password Advice Shouldn't Be Boring: Visualizing Password Guessing Attacks 

      Zhang-Kennedy, Leah; Chiasson, Sonia; Biddle, Robert (IEEE, 2013-09)
