    So, looking at James Cameron's "Avatar", I was thinking - with things like the Oculus Rift and other VR style tech coming out, what would be required to take it a step further, and include full sensual stimulation, ala Avatar? Where you can, literally, plug into a machine and go out and experience the world as though you were there, but without the danger of being there; this could be useful in applications such as deep sea/off planet exploration, scouting hostile territory for military operations, disarming minefields, etc.

    We would obviously need some way to collect the sensations we, as people, can, well, sense... and then transform that input into an electrical signal to be sent from the machine back to the pilot to be translated into something the nervous system could understand. Is there any kind of technology for this? I know we have been working on things able to interface with the nervous system, but I've fallen a bit behind in these and don't know how, or if, these have advanced at all.

    I was disappointed in Avatar because Cameron could literally have done anything in terms of the blue people's culture. And what does he do? Rips off Plains Indian culture wholesale. Then there's that imaginative name of the mineral that is so hard to get: unobtanium!

    It's especially sad that after making a classic and brilliant film (Titanic), it takes Cameron ten more years to come up with this dreck.

    Heh, the movie's plot not withstanding

    What do you think it would take to develop something with that level of sensory feedback?

    How about reality? Very old school, but pretty cool.

    What the researchers at MIT have come up with is a more sophisticated way to paint a 3D scene that changes perspective as you move around. It does away with the need to sit in a fixed, optimal position (think of how in a movie theater, everyone views the same perspective regardless of where they sit), and in fact could ultimately encourage changing your viewing angle, depending on how creative developers get with the technology. To give you an example, imagine leaning left in your chair to spy an enemy crouched behind a crate in a first-person shooter (FPS).

    The project is called High Rank 3D (HR3D). To begin with, HR3D involved a sandwich of two LCD displays, and advanced algorithms for generating top and bottom images that change with varying perspectives. With literally hundreds of perspectives needed to accommodate a moving viewer, maintaining a realistic 3D illusion would require a display with a 1,000Hz refresh rate.

    To get around this issue, the MIT team introduced a third LCD screen to the mix (pictured above). This third layer brings the refresh rate requirement down to a much more manageable 360Hz. More importantly, it means short term application of this technology is possible. Currently, TV technology maxes out at 240Hz, so a high-speed panel in the 360Hz range isn’t all that far-fetched.
