Outline

MapStory is an LLM-based animation prototyping tool that leverages a dual-agent LLM architecture to generate editable map animation sequences from natural language text. Based on user-written scripts, it automatically generates a scene decomposition that breaks down text into key map animation primitives, such as camera movements, visual highlights, and animated elements. The system includes a researcher agent that leverages LLM to accurately query geospatial information using web searches, automatically extracting relevant regions, routes, and coordinates, while allowing users to edit and query changes or additional information to improve the results. Users can also fine-tune the parameters of these building blocks through an interactive timeline editor. The system's design and architecture are detailed based on formative interviews with professional animators and an analysis of 200 existing map animation videos. An evaluation, including expert interviews (N=5) and a usability study (N=12), demonstrates that MapStory facilitates user-generated map animations, accelerates iteration, encourages creative exploration, and lowers the barrier to creating map-centric stories.

Takeaways, Limitations

Takeaways:
Streamlining and increasing efficiency in the map animation creation process through natural language processing.
Reduce the time it takes to gather information needed for animation production with LLM-based geospatial information query capabilities.
Enhance user convenience and creativity with an interactive timeline editor.
Lowering the barrier to entry for creating map animations to improve accessibility.
Limitations:
Since it depends on the performance of LLM, limitations of LLM may also affect the performance of MapStory.
Accuracy and efficiency verification is needed for processing complex or special geospatial information.
Because the evaluation scale to date is limited, the system's performance needs to be further verified through more extensive user testing.
Need to improve the aesthetic and style control of map animations.
