1. 3D Computer Interface
7 months ago
Utilizing the theory of electrostatics, we have designed a low-cost human-computer interface device that has the ability to track the position of a user's hand in three dimensions. Physical contact is not required and the user does not need to hold a controller or attach markers to their body. To control the device, the user simply waves their hand above it in the air.

    Nice! Are you going to be posting plans/designs anywhere? I'd love to hear more about the sensor circuitry.
  • Free Flow 7 months ago
    Hopefully we will have more information to give to the public soon! Thanks for the positive feedback :)

    this is amazing! nice work are you in boston?
  • Free Flow 7 months ago
    Yes, we are 5 Electrical and Computer engineering seniors about to graduate from Northeastern University.

    Now we just need some "pre-cogs" to complete the circle.

    Whats the name of the last song in that vid?
  • Free Flow 7 months ago
    The last song was just a simple beat from Fruity Loops Studio (the sound application used in the demo)

    Great stuff. I've been tracking various interfaces like the touch screen out of NYU and applications like Photosynth and posting them here tr.im/irCi and I posted this video link to the EIN Twitter feed at twitter.com/earthintelnet

    Love it. I can see tons of applications for it...

    Good job...

    Nice work, though I think it's not much different than the Fish project at the MIT Media Lab in 1995. Check it out:

    Also, at Iowa State U we're working on Sparsh-UI, an open-source multitouch API that's hardware independent and can handle touch gestures but also zcam-based open-air gestures. See code.google.com/p/sparsh-ui/

    Definitely similar to the Fish project, but a great implementation regardless. I heard Josh Smith, who was doing that research, also taught an Embedded Systems class that had a lab assignment to develop one of these interfaces:

    So cool. Scale is an issue, but consider scaling up rather than down, and the space becomes suitable for dance and music on a theatrical level. I'm guessing there's an inverse square in there somewhere, so the fall off should permit multiple units and input for isolated performers. Take a look here for a possible venue:

    Great stuff!

    Incidentally there's a woman Katya Álvarez from Mexico here at a workshop 'Interactivos' in Lima, Peru using the same Theremin principle of electrostatics to drive a mechanical plotter with a magnet. This, in effect, results in a magic table for flying metallic objects around the surface.

    Here's the workshop context: medialab-prado.es/article/taller_interactivos_lima09_magia_y_tecnologia_

    Here's a live document about the project: wiki.medialab-prado.es/index.php/La_Fuerza_en_tus_Manos

    I'll post a clip of it here soon..

    Nice.. especially dj application.. it rocks.. a nice replacement for age old mouse and hopefully keyboard later..

    definitely go toward applications with 3D geometry. nobody is developing as much there in this area, from what I can find. awesome guys.

    Luke, Mark, and Glenn,

    Congratulations on your latest honor! This video link (via hackaday.com) made its way around Moto and we were all very proud. Keep doing original work and stop in to see us next time you're in SF.

    Nice! Assuming a smaller delay I could definitely see this as a modelling tool. Or as a controller at a Bjork concert.

    People always say if they could go back in time and invest in Microsoft, they would.

    Well, I happen to think that this is the project we'll all wish we could go back in time to invest in.

    Brilliant. The applications are endless. I want one. They will want one. They will want millions.

    You sir, are going to be a rich man.

    Just blogged this thrilling development. Students! Get a ROCK STAR NEGOTIATOR on your side and don't let the big guys rip you off. npirl.blogspot.com/2009/05/mobilize-your-personal-static.html

    F**king awesome guys!

    bits base, very nice to see you all doing this. also look for this of course youtube.com/watch?v=d5EzKtn2ARE&hl=nl
    Samuel Hoffman playing the theremin. Is this the same principle or something else?

    Love to see this in action on a coffee table to control the TV and zap to a new channel ;-). Great stuff guys.

    Great work indeed guys, well done. This system applied to apps like Ableton Live, Traktor or MAX/MSP would change the way people are doing live acts.
    You should contact people at MUTEK in Montreal.
    I am sure they would thrilled to showcase something like this.

    Can I build my own?

  • Laszlo Zsolt Bordos plus 6 months ago
    Excellent work! Will you drop it on the market? - i would definately use it! Let me know...

  • ANaimi 6 months ago
    Amazing! more and smaller sensors will make it more accurate? or is it accurate enough? any health concerns these electric fields can introduce?
