GlassWatch is a comprehension companion that sits beside the video — not a harness around it. Watch normally; turn on ✦ Watching support and a panel appears next to the player with an interactive transcript, tappable terms, and a catch-me-up recap. It rides alongside whatever player you already have.
This is a real NASA film — "The Fellowship of the Telescopes" (Goddard SVS, public domain). With Watching support on, the caption in place becomes ours — translatable and tappable — because this demo uses a plain <video> we can reach; on a player we can't reach (e.g. a YouTube embed) the broadcaster's CC stays untouched and that reading moves to the companion. The companion (interactive transcript, term cards, recap, listen) works alongside any player — Glass reads the captions and explains and translates them in place.
Demo notes — the clip is NASA's public-domain film "The Fellowship of the Telescopes" (Goddard SVS) and the captions are NASA's own transcript, so they match the narration exactly. Translation, recap and term cards run on the same engine as GlassRead. Glass translates and explains the captions; the video team sees the aggregate comprehension signal on their own dashboard.
