Abstract
Interactive videos have been applied to various areas due to their engagement potential and efficiency improvement of information communication. However, creating interactive videos can be challenging because of a lack of novice-oriented guidance in current platforms, and the logic-building process when authoring interactive videos. To address these challenges, we obtained insights from four creativity support tool designers, proposed a series of hierarchical interactive video structures based on existing narrative structures, and presented the HierVid system. The system is designed as a Template-Module-Unit Mode-based hierarchical authoring platform grounded on three design requirements, and we conducted two user studies to evaluate HierVid. The results showed that novice users could get started to use and understand the functions easily, and the system allowed users to use and explore freely, with an enhanced efficiency compared to the bilibili platform. In conclusion, our research and design of HierVid offer guidance and support for novice users, making interactive video authoring quicker and more accessible.
