From Ears to Eyes: The Impact of Augmented Text Integration on Audio Guidance
摘要
As AR guidance technologies advance, delivering clear and effective instructions remains a key challenge. Audio-only guidance can lead to misunderstandings and increase cognitive load. This study investigates whether adding visual elements (text or symbols) to audio instructions on AR glasses improves user performance and experience. In a user study ( \(n=9\) ), participants completed drawing tasks under three conditions: Audio, Audio+Text, and Audio+Symbols. We measured task time, accuracy, replay count, and user satisfaction via the UEQ-S. Both augmented methods significantly reduced replays and improved satisfaction compared to audio-only, while task time and accuracy remained similar. Text and symbols proved equally effective, offering flexible options for AR instruction design.
