GazeTheKey: Interactive Keys to Integrate Word Predictions for Gaze-based Text Entry Korok Sengupta Raphael Menges Abstract Institute for Web Science Institute for Web Science In the conventional keyboard interfaces for eye typing, the and Technologies (WeST) and Technologies (WeST) functionalities of the virtual keys are static, i.e., user’s gaze University of Koblenz-Landau University of Koblenz-Landau at a particular key simply translates the associated letter Koblenz, Germany Koblenz, Germany
[email protected] [email protected] as user’s input. In this work we argue the keys to be more dynamic and embed intelligent predictions to support gaze- based text entry. In this regard, we demonstrate a novel "GazeTheKey" interface where a key not only signifies the Chandan Kumar Steffen Staab input character, but also predict the relevant words that Institute for Web Science Institute for Web Science and Technologies (WeST) and Technologies (WeST) could be selected by user’s gaze utilizing a two-step dwell University of Koblenz-Landau University of Koblenz-Landau time.
