Using gaze tracking with a CYOA-structured video or book permits another aspect of oral storytelling - noticing and adapting to listener interest. Attention focused on some character gets more scenes with them. Or the opposite? For personalized science education, might one wander the richly interwoven tapestry of stories that is science, following one's interests? I've shown people IBM's stop-motion cartoon drawn with atoms, https://www.youtube.com/watch?v=oSCX78-8-q0 https://www.youtube.com/watch?v=oSCX78-8-q0 , and they'd often ask about the ripples. IBM wrote supplementary content on them, perhaps because of such common interest. But when watching yt alone, its hard to engage, to follow up. Links in the description? Pop-up cards? With gaze tracking, one might notice the attention, and provide opportunity in that teachable moment. As if a mentor, tutor. Gaze tracking without extra hardware is still rough. And patents. But slowly it's becoming something to explore.
