Next Generation of Holographic Images 183
suman28 writes "Imagine being able to view an image from all sides and have it interact with you. Scenes or images pop-out at you and change on the fly and are viewable in full color. Best of all, you don't need head-gear or any wearable device to make this possible. They are generated by a computer with two cameras that track your eye movement and there is a transparent LCD screen between you and the display that makes the pictures come alive. Though it may be a while before this becomes part of our daily lives, it is interesting to see what the kind of research being done on this. "

There are many different cues that contribute to our perception of depth: stereo, perspective, parallax, overlapping objects, shading and shadows and changes in accommodation and convergence of the eyes.
Those with one eye lack stereo (the strongest cue), but still have a decent amount of depth perception for surviving in the real world. It is only when attempting to use devices that rely soley on stereo to generate a pseudo-3D image that they have problems.

Using any old He-Ne laser you may have lying around the house, provide the light source.
The beam from the laser is divided into two paths. One beam is used to illuminate the object; the other is just a reference beam; you could even shine them while watching Baywatch or something as long as you can keep them fairly steady during the bouncing juggly scenes.
Also, try to find something in the kitchen or basement that has eight segments coated with a high-quality aluminum to provide for reflectivity in steps from 10% to 80% at 45 incidence (use a ruler or tape measure for quick measurements).
Oh, one more thing -- the laser should be on for about a half-hour to allow it to stabilize. If it's not warmed up enough after that time and doesn't seem to be very bright at all, peek into where the light comes out while it's on to check for any dust specs that may be impacting the light's exit from the device.
Bottom line -- (cos^2)(theta) dependencies rock!

In fact, it could even be an advantage, since the guy next to you on the airplane would not realize that you are watching pr0...er, see your sensitive business documents. For other uses, say family video night, you would have to replace one screen with several of these devices. That would not have to be very expensive, especially not compared to getting one of those enormous TVs that everybody has these days.

Holography stereoscopic 3D (Score:3, Interesting)
This differences is substantial: the amount of information presented to the eye is vastly larger than simple stereoscopic methods. In a simple stereoscopic image, all objects and surfaces appear to be in the same focus plane. Holographic images essentially gain a 3rd axis of resolution by adding a very large number of focus points in 3 space.
This also allows for true perspective wherein different viewpoints provide different information. You can 'look behind' objects in a hologram, which you cannot do with steroscopic tricks.
Thus, true holograms provide a qualitativly better experience over existing 3d methods.

This is cool technology, and does have obvious practical uses as outlined in the article. But it will never replace the potentials offered by HMDs (Head Mounted Displays).
HMDs offer the the one thing you can't get from a 3rd person perspective - immersion. Unfortunately, HMDs still have some serious drawbacks, the greatest of which is the fixed focus. Some HMDs are supposedly focused at "infinity", but they are still fixed focus in that there is no way to create the different levels of focus that the real world offers the eyes - everything is at the same distance. Thus, your eyes do not change focus as they do in the real world, which leads to eye strain. Once this issue is overcome, and issues relating to FOV (field of view) vs. resolution (namely you can't get a big FOV with high resolution yet for any reasonable amount of money - it is always a trade off) are surmounted, the ability to work and play in simulated VEs (virtuals environments) for long periods of time will become a reality.
