The Holospace is a concept for a truly 3d way to interact with your computer.  It would allow for some very sci-fi interfaces and hopefully make 3d modeling and CAD a lot easier. It could display nearly any object and sense your hands or other objects to allow you to interact with the computer in 3d. In this instructable, I will show you how it would work, and then show you how I made it in 123D Design. If you like this Instructable, it would be great to get your vote for the 123D Design Challenge!

Step 1: The Display

One of the biggest parts of this is the display. It runs using four projectors, a head-tracking camera, and some shutter glasses. The projectors project onto a four sided box of glass covered in rear-projection film. Using the camera and some markers on the glasses, the computer gets the position of your head and can then adjust what it shows to make it look 3d. Here is a video with a good example of how it works: http://www.youtube.com/watch?feature=player_embedded&v=2CbiOikirrg
The shutter glasses would be used with the projectors, which are 120hz, to show a different image to each eye making the illusion even stronger, or to allow two people to share the workspace.

<p>can we make a holographic projector that would display live video from my laptop</p>
<p>Maybe, depends on what you mean.</p><p> If you are thinking of building the Holospace box and running it from the laptop, that could be possible (you would need a very powerful laptop to do anything very fancy graphics-wise though). </p><p>If you mean viewing hologram-ish things (they wouldn't technically be holograms) on a laptop screen, you could do that, but there would be a couple problems:</p><p>It wouldn't be showing a separate image to each eye, so the illusion wouldn't be as good (unless it has a 3D screen, but I haven't seen many of those).</p><p>Anything you see coming out of the screen still has to have the laptop screen behind it. If anything gets close the edge of the screen, or the user's head moves too far, it would break the illusion.</p><p>This video shows a system like that: <a href="https://www.youtube.com/watch?v=Jd3-eiid-Uw" rel="nofollow">https://www.youtube.com/watch?v=Jd3-eiid-Uw</a></p><p><br></p><p>Thanks for taking a look at it!</p>
But you can't stop light without complicated physical aperatus, this wouldn't work, it might work and a kinect-esque thing, but this isn't a 'holo-space' because it can't project onto air. Oh and in case you use this: 1 way glass is just half silvered glass, one room is dark and the other is bright, meaning that one side looks like a mirror, and the other glass :P. Nice concept though
*as a kinect-esque thing
wow cool
