The Lightbulb Computer

Nice. This reminds me how I felt watching the first pre-iPhone multitouch demos.

One small quality-of-life improvement that could be added: have the software timestamp when you say "here" and then (using a short low-FPS video buffer?) analyze the corresponding frame of video. This would eliminate the pause when you're pointing at something, waiting for the computer to respond.

Alternately a low-latency speech analyzer could look for the word "here" and quickly snap a screenshot. Perhaps project a temporary dot on the surface, so the user knows they can put their hand down now?

Quite the impressive demo! There's huge potential here.

An interesting concept. I'm (probably) one of the few people that thought the Humane Pin had an interesting idea at its core, it was just executed poorly at the wrong time. A stationary version that leans into ambience solves a lot of the interaction and engineering issues. I also like that it addresses my gripe with XR interfaces; you aren't actually sharing a digital object in space and it looks weird to everyone else.

Projectors are cheap enough for this to work.
