A Wearable AR and Gesture-Ring System for Enhancing Presentation Performance and Reducing Cognitive Load

Abstract

As remote and hybrid work models become widespread, in-person meetings remain crucial venues for expression and communication in knowledge-based work. Speakers must simultaneously convey content, manage structure, and adjust pacing during presentations. Existing presentation aids, primarily linear screen-based text, often require frequent attention shifts, making it difficult to support on-the-fly adjustments and alleviate nervousness. This paper introduces Ring-AR Presenter, an augmented reality-based wearable presentation support system. Combining AR glasses with a gesture ring, it provides low-interference real-time expression support for presenters. The system displays key information through spatialized teleprompting and structural cues within the presenter's field of view. It also enables silent, discreet content control via the gesture ring, minimizing disruption to the presentation flow. Based on a high-fidelity prototype, a simulated presentation experiment involving 20 participants was conducted. Results indicate positive effects in presentation fluency, pacing control, and subjective tension reduction. Findings suggest that presentation assistance combining AR displays with wearable gesture interaction holds application potential in real-world conference and presentation settings.
