I really don't see any advantage in these displays over current tech for the purpose of spacecraft. Interfaces with those display though...

In the automotive industry, there's a trend moving away from physical controls (single-function knobs and buttons) and towards touch screens.
While this enables more flexibility, it has a big drawback: it makes it more difficult to operate the controls blindly. Controls in a car fall into 2 basic groups:
1. controls that have to be usable while driving (lights, wipers, AC, audio)
2. controls that are acceptable if they are only operable while stationary (setting user preferences, satnav etc)

For spacecraft something similar holds. For operating a robotic arm, you need dedicated physical controls because you can't afford to hunt for them. The same goes for maneuvering the spacecraft, emergency operations etc.

its unclear to me where this is going...I've watched and been a part of the transition in airplanes (and to some extent the bridge of a ship) from purely mechanical controls and displays to heavy "screen" displays ...there is a great line from Clarke...I think its from 2010 the book but he is talking about the controls system on the Russian Lenov...and he talks about how "even in this day and age" (paraphrase) "a satisfying click" of  a mechanical switch

but clearly the trend is toward digital controls...

my old employer hasnot quite yet "digitalized" the Auto pilot flight director controls (the AFDS) but its probably coming :)

Goggles are several orders of magnitude closer to reality, and can actually be readily purchased.

For spacecraft controls, I don't see the point.
We are not going to - probably ever - see such a high information load that very simple displays aren't quite adequate for all spaceflight related matters.

This is due to a combination of low spacecraft performance, avoidance of error, and time to work things out.

Flying 'seat of pants', using information rich displays, when your current smartphone can plot the trajectory much more accurately and reliably than you can, is just not going to happen.
This is not a rapid high speed dodging firefight, it's a case where to get optimal performance out, you need optimal inputs, in precise directions at precise times, in ways humans are very bad at intuiting.

For the case where information rich displays are useful, 3d goggles built into the spacesuit are quite adequate.

When it comes to Dragon 2 and its snazzy large-sized touchscreens -- how are these things able to stand up against the vibrations, shocks and stresses of space launch and re-entry? I'd imagine that such large thin screens (tablets?) would be particularly vulnerable to such forces.

Are these primary control/viewing interfaces backed up by some kind of simpler and more rugged backup control scheme if they fail?

Are these touchscreens the most modern choices available? Or could they one day give way to Augmented Reality (AR) projections on a spacesuit helmet visor?



anything that the crew can survive (and much worse) the screens wont even notice

3D display systems are the holy grail of command and control...whoever comes up with one that 1) works and 2) is practical...changes things in a big way

Are we all worrying about something that doesn't need to be worried about?

Given that you can buy COTS touchscreens made for use in off-road racers (Baja etc.) for under $1k, yes.

Guys.
I'am pretty sure SpaceX (and Nasa) are already aware of the shock loads they are likely to see and have tested their kit on the ground to match and even exceed this.  Neither are new kids in this game and have tons of data to go test against.

Are we all worrying about something that doesn't need to be worried about?

According to the linked article above, it's a point of light made by ionizing the air at that spot:

Your first links says the light is projected onto paper dust, cellulose, in an optical trap not ionised air emitting light.

From seeker.com

The system can generate different optical effects, colors and images by using different kinds of materials for the projection particles.

“They could be just about anything,” Smalley said.  “Glass beads, diamonds, cellulose, tungsten — a wide variety of materials. What we've found most effective is a substance called black liquor, which is a byproduct of the paper manufacturing process. It's essentially just paper, cellulose."


Dammit, you're right - I guess I was quoting from a different article on a different technology that I also wanted to post:

https://www.popsci.com/secret-interactive-holograms-plasma-and-femtosecond-laser

So that one is ionized air using femtosecond lasers. This one can be made interactive, rather than just being a display - notice how the heart icon turns into a broken-heart icon when the beam is broken. But clearly it needs air for the display portion to work. The air is necessary as a display medium.
