Yeah what I want is a smart phone that has something similar that I can pull out more of the screen (or a Tablet) but the line in the middle kind of ruins it, if there can be a hard to see line in an end product it would be impressive as hell. I love the idea of having a smartphone and then extending it into a tablet format to consume video from Netflix or whatever service. Same with a Tablet, turn a 7 inch tablet to…

My absolute dream phone is something like the size of the new Samsung Note, and it would fold out to double the screen size for watching videos, and run desktop Linux/Win10. I could then use a Bluetooth keyboard and mouse like I can now on Android, and it could be my only device I own.

Sounds like you want the Samsung Galaxy X[0]. If it runs Dex (unclear right now) you'll get desktop Linux in a foldable phone with bluetooth capabilities. I believe the screen is going to be 7.3" but not sure if that's unfolded or folded.

Sounds pretty awesome. I'm keen to see what it ends up being. Not sure why they would need a curved battery. I'm imagining it like a book, with just a normal flat battery each side. Maybe they're thinking like a loosely folded piece of paper before it creases.

The actual engineering behind this is neat. The prototype nor demo video seemed very alluring. Perhaps someone will take this idea and do something interesting with it. At the moment I don't see it improving upon the current smartphone.

All the moving parts and flexible pieces seem like a failure point to me. I'd like to see something that can project a touchscreen onto a tabletop.

Something you keep in your pocket that projects itself to different screens around your home would be interesting too, and anywhere you go.

They sold smartphones with projectors a few years ago. They were bulky and not very popular. One issue with current projector technology is keeping the image straight. You also need a place to rest the device near the surface. Logistically it’s a pain. Future tech could improve this, but right now it’s not great.

What would be the killer application for this technique? I don't see the advantages, because the thing is clunkier than a smartphone and handling it seems odd. What I want is a smartphone the size of a credit-card, that can project a bigger screen on a flat surface (e.g. table or sheet of paper).

> What I want is a smartphone the size of a credit-card, that can project a bigger screen on a flat surface (e.g. table or sheet of paper). That also sounds very clunky to me. Projection requires a white, yet unlit surface to work well. People are unlikely to have one of these handy while out and about. Added to which, it makes touch control impractical, except in the case of back-projection.

You project a keyboard too, in a different direction. Then a Lidar sensor to detect finger position.

When is it okay to say something is engineering vs science? Personally I would classify this as engineering. Not so sure...

I think you'll get as many answers as there are opinions.

FWIW, to me the line in the sand is drawn where you need to build it in a reasonably cost efficient manner. (Which is to say, most science involves engineering to some degree. NASA and the LHC need to try to make what they do fit in some budget at the end of the day.)
