Informational videos are difficult to scan and navigate

Lecture videos, tutorials, and livestreams are somewhat opaque objects. The medium is most naturally viewed linearly. That works well for narratives, but much less well for informational content, which is sometimes best consumed (or referred to) non-linearly.

Some attempts to solve this:

• Twitch et al’s “clips” / “highlights” features, which allow post-hoc segments to be labeled and surfaced
• Pavel, A., Reed, C., Hartmann, B., & Agrawala, M. (2014). Video digests: A browsable, skimmable format for informational lecture videos. Proceedings of the 27th Annual ACM Symposium on User Interface Software and Technology, 573–582
• Lu, Z., Heo, S., & Wigdor, D. J. (2018). StreamWiki: Enabling Viewers of Knowledge Sharing Live Streams to Collaboratively Generate Archival Documentation for Effective In-Stream and Post Hoc Learning. Proceedings of the ACM on Human-Computer Interaction, 2(CSCW), 112:1-112:26
