Multitouch table uses a Kinect for a 3D display

[Bastian] sent in a coffee table he built. This isn’t a place to set your drinks and copies of Make, though: it’s a multitouch table with a 3D display. Since no description can do this table justice, take a look at the video.

The build was inspired by the subject of this Hackaday post where [programming4fun] was able to build a ‘holographic display’ using a regular 2D projector and a Kinect. Both builds work on the principle of redrawing the 3D space in relation to the user’s head – as [Bastian] moves his head around the coffee table, the Kinect tracks his location and moves the 3 dimensional grid of boxes in the opposite direction. It’s extremely clever, and looks to be a promising user interface.

In addition to a Kinect, the coffee table uses a Microsoft Surface-like display; four infrared lasers are placed at the corner and detected with a camera next to the projector in the base.

After the break you can see the demo video and a gallery of the images [Bastion] put up on the NUI group forum.

    wow! nice build!

    I can’t help think what an epic Minecraft editor this could make.

    AMAZING!

    You need to completely integrate the entire Mine Craft game into this!

    Wouldn’t there be a way to extract 3d data from the anograph?

    Mine Craft?

    @anybodysgues, thats anaglyph and i would imagine it wouldnt be to hard to extract that data from it. However a small mod could probably export the data in a more native format for the table.

    There was a kid doing this kind of stuff with Wii controllers back when they were new. Mounted two IR LEDS on a pair of sunglasses to make a “sensor bar”, and had the wiimote on top of his monitor to sense what angle he was looking from.

      Meant to say up front, this table is still cool as shit, and not having to wear a sensor bar is extra winnage.

    • Caleb Kraft says:

      Yeah, that “kid” went on to be on the team that brought us the Kinect. He also paid for the bounty that brought us the open source driver for the Kinect.

        I’ve always loved Johnny’s work. He’s done some of the greatest hacks of all time in my opinion. I check his blog regularly and love reading what he’s working on.

        Ps. He’s shifted from working on the Kinect now to working at Google X. Working alongside the guys doing Google Glasses and the self driving car.

    This looks cool! I wonder though, would it end up like that thing in Mission Impossible 4 where it messes up perspective when two or more people are in the frame? I don’t know how you’d accomodate for that…

    I think this would look downright incredible with a Microvision picop projector with it’s virtually inimitable contrast.

  8. Adam says:

    Wow, that is great. Have you had any problems with the Kinekt getting bumped? If so, you could attach it to the ceiling.

    Here’s a thought, you could stack two LCD panels to make your display glasses-free 3D.

    Similar to this approach (http://www.youtube.com/watch?v=YrRnURU1W3E), but instead of multiple 2D images just use the overlapped barriers to create a single 3D image that changes based on the Kinect head-tracking. Bonus points if you super-size it with dual 120HZ HDTVs.
