Yep, this is sort of what I'm waiting for. Though I have no need for a bigger screen.

The Apple iWatch sort of tried with the smaller size, but frankly, I think it's ridiculous. Why wear another device on your wrist that is connected to your phone? Perhaps I misunderstand the tech.

Sort of like when people where wearing Blue tooth hearing buds in their ears where ever they went so they could look like an android that talks to itself.

Myself, I'm in GIS, so am no stranger to new technologies. But sometimes you have to just say. "Um... No."

You can buy it for yourself.



As for adapting it to phones, I don't know if the physics of it would allow it to scale properly, but there will soon be phones (and televisions) where the screen is the speaker.

OTOH, since the system is dynamic, the phone camera could track you and direct the sound to wherever you were relative to the phone. (And to the person standing behind you! )
The new technique doesn't use any speakers, just a laser and a rotating mirror. Here's an article on it.

I got that. But try adapting it to something like smart phone world.

A hijack, if I may. Could this technology not be used 'in reverse' to eavesdrop on a unsuspecting target? (And, possibly even through, say, a window pane?)

For a window pane, you're probably better off with a laser microphone. And for general remote listening, a parabolic microphone will do the trick.

That said--yes, microphone arrays are a thing. In fact, the Amazon Echo devices (and probably similar devices) already use them for noise isolation--they can listen clearly to an individual speaker even when there are other noise sources in the room. Mine show me a little LED indicator in the direction I'm standing in.
