Tangible Display Makes 3D Touchable 112

moon_monkey writes "Researchers in Japan have developed a display that makes 3D objects solid enough to grasp. The system, created by engineers at Japan's NTT, combines a 3D display with a haptic glove, making 3D items that look real but also feel solid to touch. Two cameras are used to image an object, to make the 3D image. A computer also uses this to render a solid representation. It could be used to inspect products remotely, or even to shake hands with someone on the other side of the world, the researchers say."

    Get money from pr0n kingpins. Bring them into the family and let them subsidize this tech/form their own group of researchers to specifically pursue porn related applications. It will get to market so much faster than if left to academics..

    My interest would be to explore new human/computer interactions (not like that sickos). The 2d nature of monitor systems is only slightly less annoying with the new 3d super gee whiz flying through space multiple workspace navigation systems.

    A haptic glove with sensitive feedback mechanisms and a graphical interface that allows organization of workspaces/workspace elements in an untethered 3d environment is something I have always wanted. Add in some good voice recognition and a chair designed so you can rest your arms while still retaining full range of motion with the gloved hand.

    It would be the interface of my dreams.

      While 3d workspaces certainly would have their applications (medicine for instance), IMO for the average individual 3d would be merely re-creating the physical workspace that the 2d interface replaced. The 2d space is useful because it is an abstraction/simplification of the work that was previously done in 3d.

    So does this mean that there is a possibility of realtime or "live" 3D encounters, no I do not think so. At this point it may be able to scan in one object and display it for feeling but doing it where new things can be scanned and created anywhere realtime would need processing power way beyond what we have so to all you sickos out there this probably wont be of much use if you like anything better then a plastic bag full of Vaseline.
    • I don't imagine any heavy processing requirements here. Collision detection on 3D objects is done in almost every 3D game. The nodes in the glove are equivalent to a few other moving game objects colliding with the 3d object in question. How many games have you seen that can handle that workload? Quite a few, I think.

      This article is B.S., though. This isn't a "tactile display", it's just a 3D display, much like we've had for decades, with a force feedback glove attached.

    I remember using a haptic glove like this at Comdex like 10 years ago. The display wasn't 3D, but other than that, it was essentially the same thing. The glove had force-feedback motors in each fingertip and when you grasped one of the objects on the screen, they provided tactile feedback representing mass, weight, and to a much lesser extent, texture. In the demonstration, you had to stack blocks of varying types. Very simplistic, but also very very cool. I always wondered where the tech went since I never saw it again after that.

    This idea goes back a long way. I think it was first tried in the 1970s, using the input end of a remote manipulator arm intended for handling radioactive material. It's been done dozens of times since then. The problem is doing it well.

    We have enough compute power now to get the lag down to a few milliseconds, which was a big problem ten years ago. Then it's mostly a mechanical design problem. Most of the devices so far were too clunky. Is this one better?

Otherwise some other form of feedback (e.g. electrodes in brain) may have to be thought of to simulate different 'touches'. The way its currently built, everything will feel the same. T

      Actually since the virtual surfaces are modeled in software, it all depends on the parametric model you are using. So, with the appropriate model, you can modify an object's feeling of "stiffness", or make it elastically deformable, change its texture, etc. Just like how 3D graphics can have objects with different textures, bump maps, and physical behaviour.
