Abstract

This paper introduces a timeline authoring tool that integrates Augmented Reality and tablet-based spatial interaction, enabling users to create large-scale non-linear timelines by leveraging spatial cognition and embodied interaction. In this system, the AR headset provides a large, immersive space for visualizing and interacting with a room-sized 3D timeline, while the tablet allows for precise sketching, annotation, and sculpting of timeline structures such as curves and branches. We conducted a design workshop to explore the user experience with this tool, which supports the creation of diverse expressive timelines for two datasets.
