Writing on Standing Water
A reader writes "Engadget is reporting on Japanese scientists who have found a way to 'write' characters on the surface of water using waves. This looks very cool - but the time required to change character seems very high (15-30 seconds). From the article: 'Liquid-based displays are nothing new -- in a vertical orientation, at least -- but apparently it's a lot more difficult to coax a standing pool of water into forming recognizable shapes and characters.'"
"My name is written in water" has lost all it's meaning, now!

Looks pretty cool, what are some of the real world applications of this?

Because it's COOL. Who needs practical application?

Now only if they can do this in 3D like in the movie Abyss. (Yes I know, it was CG animated)

For example, writing a word in water and having the perimeter of the pool recognize the waves, and convert it to digital text. Microscopically, that could actually have a use with a liquid enclosed touchscreen.

Interesting, but why would someone want or need to do this? I fail to see any problem or application that this could possibly solve or address.
Wait. I could be in swimming pool, and the lifeguards could use this tool to "write" in the water to get out, or that someone is drowning, or that there is a sale on cold beers at the concession stand. That's it... advertising... there is an applicaton! Maybe I answered my own question.
In any case, for those that RTFA, it would be quite a scary pool to be swimming in, with all those magnents around the edge of the pool.
BTW, this is the 2nd time I've recently seen the word "coax" used in an article. Frightning.

Over on engadget, they had serious comments about using resin, vacuuming forming, advertising, and other practical applications.

That sure makes it sound like the calculations involved are so great that the computer takes that long to process (as opposed to a physical delay in the hardware or medium). Certainly that could be reduced substantially either by optimization or throwing more CPUs at the problem. If that is indeed the issue then they could also precalculate the math for various shapes, and recall them instantly on demand. I also wonder if this is a purely virtual simulation inside the software, or if the system requires feedback from sensors in the real world to fine-tune the oscillations to produce the desired effect. In that case it may take that much time to stabilize the system because of chaos and the like. I have a hunch that must be what's going on, because certainly these people are smart enough and have enough funding so that processing speed alone isn't the issue.

These scientists can apply an amazingly controlled level of force to a specific point on a 2-D surface across something a unpredictable as the surface of water. Imagine bringing this down to nanotechnology level, could the same principles allow someone to sculpt an object out of individual atoms from the center out?

Back in college, I toyed with the idea of doing something like this as my senior project. My name for it, at the time, was a "water hologram", which I think more-accurately describes what's going on. You're manipulating one or more wave sources in order to generate a specific pattern of constructive and destructive interference.
I'd like to see a video of it. I'm curious to see if the images are: A) constantly oscillating up and down, B) perpetually raised and not oscillating, or C) just there for a moment and then gone (like a rogue wave or something).
And for their next project... Robert Wilder.

It seems they've reversed this process and solved for the axial data given the point-by-point data - e.g. the rasterized character.
By the way, CAT scans and Bessel functions are one of the examples of "abstract" math that later turns out to have practical application.

That only shows how useful SF can be! ;-)
Read the hyperion-serie myself several years ago, and found it to be quite good. Especially the first two books are definately above the SF-average (and I've read a lot of SF and fanatsy).
No doubt some day, someone will make a movie out of it, and there will be a 80% chance they screw it up big time... after all, I know only of a handful of films that are equal or better then the books they're based on.
Another very good one, but contrary to Hyperion very unknown, is 'the ring' (at least, that was the translation of the title). Strangely enough, there isn't even a reference to it on wikipedia, so either the original title is different, or it's truelly a gem of a book who never got the attention it deserved.

The picture seems to show about 60 solenoids around a small pool of water. When they're all clacking away they'd make one heck of a din. The writing looks amazing, but I can't see e.g. a hotel wanting this thing in the lobby unless it can be made very quiet.
Also, do you remember how yogic flying made the news a few years back. The photos seemed to show these guys hovering in mid-air, but in fact they were just "bottom-hopping" up and down and someone clicked the shutter at the top of their bounce. I'd like to see a video of this pool to check that the writing isn't only readable for a tiny fraction of a second.

...I've been able to write me name in the snow for years.
Sometimes they do it on a large piece of blotting paper and carefully place it on a large bowl of water. The paper soaks the water and sinks, leaving behind patterns floating on the surface of water.

The nature of water being fluid means it would be unlikely the character would remain for long, unless the agitation level was very high. Which may well be the case... Water can seem pretty solid if it's under enough pressure and/or moving fast enough. Also, based on the PDF and the Akiken website, looks like this was something they developed in 2004. But presumably it wasn't published at the time...

It seems that the key to manipulating the water's surface in this manner is creating an interferance pattern just as in a hologram. Does this development have any bearing on holo-technology?
So, you're telling me that Writing on Water can only do between 1/15th and 1/30th of a frame per second on your machine? Damn - don't you think it's about time that you upgraded your Wave Processing Unit?

Wonder how no one thought of it. But, if you could manipulate reflective liquid surfaces like, say, mercury, you could create a really huge mirror.. I had read an article once about mirrors being made from liquids using centrifuges, but this could be a more accurate process.
