The Hovering, Holographic, Star Wars Display

Tweetergif

While we’re still a long way off from the Star Wars telepresence holographic displays, this build over on the Projects site is the closest we’ve seen yet. Even better, it can be built in a garage for not much money.

Inside the Hoverlay are a few fans and a pair of ultrasonic atomizers that turn water into an extremely fine mist. The fans pull this vapor up through the base of the display and through simple drinking straws to create a laminar sheet of water vapor. Put a projector behind this thin sheet of vapor, and you have a display, seemingly floating in mid-air.

The base of the display can be scaled up, simply by putting several units together in a line. It’s still just a prototype – future versions will improve the stability and reduce the thickness of the fog layer – but it’s still a very cool build for a custom holographic display.

More Kinect holograms from [programming4fun]

[programing4fun] has been playing around with his Kinect-based 3D display and building a holographic WALL-E controllable with a Windows phone. It’s a ‘kid safe’ version of his Terminator personal assistant that has voice control and support for 3d anaglyph and shutter glasses.

When we saw [programming4fun]‘s Kinect hologram setup last summer we were blown away. By tracking a user’s head with a Kinect, [programming] was able to display a 3D image using only a projector. This build was adapted into a 3D multitouch table and real life portals, so we’re glad to see [programming4fun] refining his code and coming up with some really neat builds.

In addition to robotic avatars catering to your every wish, [programming4fun] also put together a rudimentary helicopter flight simulator controlled by tilting cell phone. It’s the same DirectX 9 heli from [programming]‘s original build. with the addition of Desert Strike-esque top-down graphics. This might be the future of gaming here, so we’ll keep our eyes out for similar head-tracking 3D builds.

As always, videos after the break.

Building a multidimensional display from trash

Here’s a simple concept that will let you turn any LCD screen into a multidimensional display (translated). [Herdek] used bits of that impossible to open clear plastic packaging to construct this add-on for the smart phone seen above. Three pieces of the material have been mounted at a 45 degree angle between the screen and viewer. The material is both reflective and transparent, depending on the angle at which light hits it. This allows it to reflect the light from the screen toward the viewer, but let light from the baffles behind it pass through unimpeded. The three baffles allow the LCD to be partitioned into three different sections whose images will appear to be at different depths according to the viewer’s vantage point. After the break we’ve embedded a demonstration video, as well as the how-to that shows the construction technique for the add-on.

This follows the same concept at the pyramidal volumetric display, which is still one of our favorite LCD hacks.

Tangible holograms

As you watch that video, you’ll probably find yourself wondering several things about the tangible hologram project. Why haven’t we seen these simple hologram setups used more often? Where did that cool air puff system come from and why haven’t we seen more on that?  When will this be integrated into the latest Xbox/PS3/Wii? We don’t know the answers to those questions, but we would really love to play with this in person to see how convincing it is.

Election night holographic interviews

obama_holo

Instead of the normal head in a window or split screen display used when interviewing remote guests, [Wolf Blitzer] will be interviewing 3d holograms. Supposedly, they will be recording in a way that allows for 360 views to be projected on stage with [Wolf]. We’ll have to wait and see exactly how they plan to pull that off, but our suspicion is that it will be similar to the Gorillaz live performances. Join us after the break to watch one.
