Force field tech may make touchable holograms possible

[IsaacC]

A device that uses ultrasound was used to create invisible 3D forcefields suspended in midair. It won't help you with an oncoming missile, but there are other possibilities. And as Gizmodo said, when I mean possibilities, "I really mean 'virtual sex.'"

This technology is tactile, meaning you can touch it, and it gives the appropriate feedback to the computer. Which means that if you can apply light technology to it, you can actually create touchable holograms. Holograms that can touch you back. Ok, that sounds dirty, but I couldn't get how the developer of the tech described it out of my mind:

This tactile display enables tactile feedback superimposed over 3D graphics projected in free space, which provides more intuitive handling of 3D "touchable" graphics. For example, users could touch Princess Leia projected in the air.

The tech is even said to let you feel the nature of the material. It's the holodeck just waiting to happen.

I upped your post count so that posting links should work moving forward for you. Also, for the youtube tags, you only need to paste in the part after the equal sign for it to work.

On topic - This is very cool.

[IsaacC]

Thanks, that'll make things easier ^^

Very cool. Very.

Finally got that YouTube vid to work too, thanks

Woah, this sounds like something out of a Star Wars film. I can't wait untill we start to see these in our living rooms!

Um... if it's real, why can't they just drop the paper onto the field and let it sit there?

Seems like paper on a string to me... but if it was at SIGGRAPH, who knows.

freeplay, i'd say the reason is probably because the "force field" is easily breakable, for example that chick was bearly touching the thing, which means, it's either not real, or an increadibly fragile "force field", hopefully though it is real

[IsaacC]

the "force field" was made using airborne ultrasound tactile display, which, from what i understand, uses sound to create pressure. from how it looks in the video though, it seems it's not strong enough to keep solid objects afloat in midair, but it's enough to give tactile feedback to the computer.

maybe someday they'll be able to make the field strong enough to feel solid. but that might become too strong that it becomes dangerous for humans?

[slicer4ever]

at least it's a good start in the field of "force fields", however i'm not an expert so maybe it's not a good start, but a far behind one, but idk

How can you possibly say that about something INVISIBLE?

I think technology like this has existed for a while actually. Wiki "Acoustic levitation".

I'm hoping that Emotiv Systems get involved in this though. They're the group that are working on some video gaming peripheral that apparently:

Reads and interprets players’ conscious thoughts and intent and can differentiate between multiple conscious thought commands. The Cognitiv suite reads the player’s thoughts and intent, such as lifting an object, and sends commands through the API to levitate the object in the virtual world. (A demo application demostrated: lift, drop, push, zoom, left, right, rotate CW (object), rotate CCW (object), rotate left (player), rotate right (player), rotate backward, rotate forward and disappear (object).

What I'd be interested in seeing THAT software applied to objects in the real world by combining this research with Emotiv's.

That tells you nothing about the pressure she's exerting.

How about this?

As long as it's a fairly sturdy pressure, couldn't you, hypothetically, stick a few under a car, which then causes it to hover? As long as the field is the right shape, as well as pretty flat, it could eventually work.

We could definitely be seeing what was fiction, and presumed impossible, but now possible.

If it's strong enough, then I would imagine that yes, it would be possible. Judging by that video though, it probably isn't very strong. You could probably push your hand right through it.

i guess that's true, however just from my perspective she appeared to be exerting very little pressure, but i guess we'll have to wait until it goes commercial to know(however i suspect that when it's released it'll probably be capable of a lot more)

it can have practical applications with its current pressure sensitivity i think. maybe have a keyboard pop up anywhere in midair. less clutter on my desk. or a remote control - that'd be great. i won't have to look under the couch for it everytime anymore.

F*ck ya, master ownage.

Cool stuff like this never gets finished, and is it does it never gets publicly released.

[Zx30]

I gotta agree with Freeplay. The ultrasound image was enough to BEND the paper, but not hold it? They could of at least shown what would happen if they let it go.

[JEMdev]

this looks pretty cool

[iluvpspz]

wow is this possible like really?
