User Adaptation to a Faulty Unistroke-Based Text Entry Technique by Switching to an Alternative Gesture Set Inproceedings

Ahmed Sabbir Arif, Wolfgang Stuerzlinger

Abstract:

This article presents results of two user studies to investigate user adaptation to a faulty unistroke gesture recognizer of a text entry technique. The intent was to verify the hypothesis that users gradually adapt to a faulty gesture recognition technique' s misrecognition errors and that this adaptation rate is dependent on how frequently they occur. Results confirmed that users gradually adapt to misrecognition errors by replacing the error prone gestures with alternative ones, as available. Also, users adapt to a particular misrecognition error faster if it occurs more frequently than others.
