RealityTalk: Real-Time Speech-Driven Augmented Presentation for AR Live Storytelling
This addresses the need for more engaging and expressive tools for live AR presentations, though it is incremental as it builds on existing augmented presentation concepts.
The authors tackled the problem of creating interactive and improvised augmented presentations for live storytelling by developing RealityTalk, a system that enables real-time speech-driven manipulation of virtual elements, and they evaluated it from a presenter's perspective to show its effectiveness.
We present RealityTalk, a system that augments real-time live presentations with speech-driven interactive virtual elements. Augmented presentations leverage embedded visuals and animation for engaging and expressive storytelling. However, existing tools for live presentations often lack interactivity and improvisation, while creating such effects in video editing tools require significant time and expertise. RealityTalk enables users to create live augmented presentations with real-time speech-driven interactions. The user can interactively prompt, move, and manipulate graphical elements through real-time speech and supporting modalities. Based on our analysis of 177 existing video-edited augmented presentations, we propose a novel set of interaction techniques and then incorporated them into RealityTalk. We evaluate our tool from a presenter's perspective to demonstrate the effectiveness of our system.
