Alternative methods of producing 3D.. and it's future?

I thought I'd start a thread to discuss alternative methods of producing 3D no matter whether they are practical for TV viewing or not.

A few of you will have seen the Wii-mote hack by Johnny Lee, it's a wii-mote and sensor bar reversal combined with some basic code to make it work for a single viewer and would probably be best suited for a gaming platform.

Watch the vid here, it's more impressive than it sounds..

Another minor idea (that sadly would be limited to a single viewer) which could improve the 3D viewing experience could be an eye focus tracking camera that could bring objects we view on the screen into focus and blur others outside the depth of field to simulate human peripheral vision.

See HITLab Projects : True 3D Displays



What else is out there? What is likely to be the next thing after spectacle-free 3d?

Discuss..

Pretty impressive but I cant believe all these people are at a 'concert' just to watch a holographic image.. crazy Japanese!?

ipabze- That is pretty cool, similar to the wii-mote hack but taking it a step further.


A few of you will have watched this.. The Gadget Show recently spent a lot of money making this BF3 based battle simulator, lots of ideas were implimented and they pulled it off quite brilliantly Imo. They even had Andy McNab in for a shot of it and he loved it so much he wouldn't come out.


:D

Those videos are amazing, the 3d effect on that first video is great. And i would love to try out that battlefield 3 setup :)

As a gamer i'm excited about what the next gen will bring. This gen they are just finding their feet and experimenting with the tech.

Kinect and move have been a bit underwhelming but Im sure it isn't going to be long before we can interact with 3d objects hovering in the middle of our living room , i personally can't wait to see what the next few years hold.

The BBC are clearly planning ahead, the future looks good for 3D!

Some of the technology in their recent R&D White paper sounds very impressive... particularly Helium3D's direct projected view RGB laser display.

HELIUM3D is creating a 3D display that will extend the state of the art in autostereoscopic (glasses free) displays. The HELIUM3D display technology addresses the effficiency and colour limitations of current and next generation displays by developing a new display technology based on direct-view RGB laser projection via a low loss transparent display screen to the eyes of viewers.

"The fundamental features of the display are:

  • Support for multiple viewers
  • Allow for viewer freedom of movement
  • Motion parallax to all viewers
  • High brightness and colour gamut
  • Viewer gesture/interaction tracking
  • User-centred design, ensuring that future products are "fit for purpose" in terms of perception and usability
Several viewing modes are possible including: motion parallax (the 'look around' capability) to each viewer, privacy of viewing from other viewers, a different camera viewpoint to each viewer and also conventional 2D to all viewers providing backward compatibility when necessary. This gives a display with a very wide range of applications and modes of operation.

The display and its viewer interaction technology will serve both consumer and professional applications. 3D television and 3D video gaming are the most important consumer applications, in which viewer gesture recognition can be a natural replacement for remote controls and game controllers.

The display also has a broad potential in professional applications, including medical imaging, video conferencing, engineering design, and oil and gas exploration. In these applications, gesture recognition can be the basis for device-less hands-free interaction within the 3D object viewing space.

The HELIUM3D project builds upon and adyances key technologies deyeloped in the EU funded 3DTV Network of Excellence, the MUTED(Multi-User3D Television Display) and the ATTEST (Advanced Three-Dimensional Television Systems) projects. Helium3D will lay the foundations for an autostereoscopic video display capable of being developed into a product that will be in use within the next ten years.


The HELIUM3D display will use pupil tracking to control and direct the light output to the viewers' eyes. The display operates by steering the horizontal direction of light emitted from the surface of the screen where columns of the image are scanned horizontally. High accuracy, low latency pupil tracking and a high display frame rate permits many modes of autostereoscopic operation to multiple mobile viewers due to the ability of the display to present a different image to every eye.


The goal of HELIUM3D is to reproduce images that are of sufficient quality to have virtually the same subjective appearance as holograms but without the attendant complexity and redundancy of information. This is achieved by exploiting the advantages of accurate pupil tracking, fast display frame rates and awareness of the limitations of the human visual system in terms of visual and stereoscopic acuity, thus overcoming the limitations of current LCD technology.
In producing such an advanced display HELIUM3D will also address new viewer interaction techniques in the near-field (distances within arm's reach of the display such as computing or medical imaging) and far-field (applications beyond arm's reach, such as domestic television or video gaming) that will be made possible by the new technology."






Sounds like a multi-beam, multi-person VRD (virtual retina display) laser projector which is also currently being developed for single eye spectacle wearer use where the RGB laser projects the image directly onto the eye retina.
