• ExNovo: A user interface that supports novices without encumbering experts

  Mark Blair, Amanda Klassen, Justin O'Camb, Cal Woodruff, Rollin Poe, Christine Chuong, Robin Barrett (2026) — ACM Games

  ExNovo is a novel hierarchical tree menu interface designed to bridge the long-standing divide between graphical user interfaces (GUIs) and keyboard hotkeys. Traditional GUIs scaffold novice users by making command options visible, but their reliance…
