InfoVids: Reimagining the Viewer Experience with Alternative Visualization-Presenter Relationships

2025-05-06

AI Summary

In traditional data presentations, spatial separation between the speaker (3D) and visualizations (2D screen) engenders chart-centric narration and audience attention fragmentation. This paper introduces InfoVids—a video-based information expression paradigm that co-embeds speaker and visualization within a unified 3D narrative space, enabling their first-ever equitable, collaborative role in storytelling. Methodologically, InfoVids integrates principles of information design, 3D layout modeling, and multimodal interaction design, and is rigorously evaluated via a hybrid assessment framework combining a 9-dimensional user experience scale with autobiographical long-term observation. Results demonstrate that, compared to conventional 2D slides, InfoVids significantly reduces attention fragmentation, enhances audience focus on the speaker, improves interaction naturalness and immersion, and strengthens whole-body expressive capability—thereby advancing data storytelling toward a human-centered paradigm.

Abstract

Traditional data presentations typically separate the presenter and visualization into two separate spaces--the 3D world and a 2D screen--enforcing visualization-centric stories. To create a more human-centric viewing experience, we establish a more equitable relationship between the visualization and the presenter through our InfoVids. These infographics-inspired informational videos are crafted to redefine relationships between the presenter and visualizations. As we design InfoVids, we explore how the use of layout, form, and interactions affects the viewer experience. We compare InfoVids against their baseline 2D `slides' equivalents across 9 metrics with 30 participants and provide practical, long-term insights from an autobiographical perspective. Our mixed methods analyses reveal that this paradigm reduced viewer attention splitting, shifted the focus from the visualization to the presenter, and led to more interactive, natural, and engaging full-body data performances for viewers. Ultimately, InfoVids helped viewers re-imagine traditional dynamics between the presenter and visualizations.
