This is a really cool project.

From the end of the video:

> I had the bars of music auto-sending at a preset interval. The pedals, instead of flipping bars, temporarily pause the flipping or speed it up, in case I'm desynced from the glasses.

That's how teleprompter apps work. Of course the difference is that when speaking you can pause a little if you get desynced, while with music you're like "on a train" and if you pause, it shows. But having an interval is not shocking.

Maybe the problem with this is that typically, sheet music resolution is not constant -- if there are many short notes it will result in a larger space on the page (a larger bitmap) than if there are few long notes.

So maybe an approach is to send a fixed number of bars, regardless of their actual size, so that the interval can have a constant relation with the tempo of the piece?

> My dream smart glasses would just listen to the performance and automatically flip bars

Couldn't the phone do that? The phone is already the part doing most of the work.
