🤖 AI Summary
Existing data storytelling systems predominantly rely on gesture- or voice-based interaction, leaving physical-object-driven visualization control unexplored.
Method: This paper introduces an augmented physical data storytelling approach that systematically establishes the first formal mapping between physical manipulations and visualization commands, enabling a real-world-operation-based visualization control system. The system integrates depth-camera-based object tracking with Vision-Language Large Models (Vision-LLMs) for event recognition, supporting real-time physical action detection and natural, bidirectional coupling with digital feedback.
Contribution/Results: A user study demonstrates that the method significantly enhances interaction intuitiveness, presentation fluency, and audience engagement—thereby empirically validating the effectiveness and practicality of physical interaction in data storytelling.
📝 Abstract
Augmented data storytelling enhances narrative delivery by integrating visualizations with physical environments and presenter actions. Existing systems predominantly rely on body gestures or speech to control visualizations, leaving interactions with physical objects largely underexplored. We introduce augmented physical data storytelling, an approach enabling presenters to manipulate visualizations through physical object interactions. To inform this approach, we first conducted a survey of data-driven presentations to identify common visualization commands. We then conducted workshops with nine HCI/VIS researchers to collect mappings between physical manipulations and these commands. Guided by these insights, we developed InSituTale, a prototype that combines object tracking via a depth camera with Vision-LLM for detecting real-world events. Through physical manipulations, presenters can dynamically execute various visualization commands, delivering cohesive data storytelling experiences that blend physical and digital elements. A user study with 12 participants demonstrated that InSituTale enables intuitive interactions, offers high utility, and facilitates an engaging presentation experience.
