In that demo, the lightbulb sits on the desk, less than a meter away from the page. What feels implausible about this setup? This is kind of thing you can do with your smartphone today.
So is the demo real or is it smoke and mirrors? Could you have pointed at other words and have it work?
(I think I overestimated how much of an angled shot it was the first time I saw it, on top of how easy or hard turning your finger into “actually capture this text”… but you’re totally right that in principle a camera at a non agressive angle can capture that text)
(I like this overall concept a lot! Cooking is the right example, voice interfacing’s 96% use case is basically “my hands are dirty but I must use computing”)

It doesn't feel implausible, it is implausible, because your idea would require either a camera with good optics pointing in a specific direction, which means it's no longer a set-and-forget lightbulb, or some kind of 360 view more-or-less 3D camera to cover all the angles, which probably isn't going to have the resolution to read angled text at that distance.
At the very least it's going to have a range limit on that feature.
And there's a projector in there too.
In something smaller than a smart phone.
It's a great concept, but not a very workable one. Kitchens get steamy, tables can be huge, and management will want to use the cameras for user surveillance.
