When (if ever), we will be able to recreate the famous scene from Star Wars R2-D2, which reproduces the message of the word Princess Leia hologram? Unfortunately, we are far from being able to transmit 3D video from pico projectors on our phones and laptops, but the technology exists.
Researchers at the University of Arizona in Tucson have created a system to capture a 3D image and send it to (almost in real time) throughout the world. According to the website of the journal Nature, the team of "system acquires information about the 3D shoot from different angles with 16 cameras, each with a second image of the object. 16 view of the holographic pixel data is processed on your computer."
The result of three-dimensional holograms are tiny and slow, but that might have one at home in 2020. I can not wait that long? TrueConf videoconferencing specialist has developed a 3D version of its popular business software, which can transmit a video sequence in 3D thanks to cameras mounted on two PC monitors. Participants of the conference to put the Nvidia 3D shutter glasses for full effect. TrueConf 3D will be available in late 2011 at a price of $ 5,000 (about £ 3000).
I think the 3D surround sound is solid? Think again. Although traditional 5.1 and 7.1 speaker configurations can produce a rich sound image and the audio mix to conform to specific channels and investments from the speakers. The closest you're sitting in the sweet spot of 11.1, which consists of five speakers (two of them up), four side speakers, two rear speakers and a subwoofer. This is not ideal for most households.
We really need is a virtual solution, and Edgar Choueiri, a professor of physics at Princeton University, is close to us give. Disappointed with the traditional realism of surround sound, audio Choueiri developed a filter that works with standard stereo speakers.
"With 3D, I can get a fly to go around your head," he told the BBC Today program. "Or if you really want to scare someone, you can put a sound to the inside their heads. "
Professor Choueiri work has the potential to revolutionize audio, and has recently signed a partnership with Cambridge Mechatronix (LMC) system development Dynasonix 3D sound.
According to CML, the technology works by focusing a pair of sound beams in each of the ears of many listeners, track your positions in real time with a camera and the provision of cross-talk canceled 3D audio for each listener . As a result, each listener receives its individual sound field.
"This gives you an audio experience similar to headphones but without the helmet," said the CML.
What do you do when you want 3D without glasses, but you can not just project a 3D image? If you are sensitive, you wait 20 years for technology to catch up with your plans. If not, you ask people to squint to stitch patterns with figures of around 30 frames per second.
This is the simulated 3D magic carpet ride, a game in 1994, and if you can play well, you've won a prize. The prize: a lifetime supply of paracetamol for a headache that would soon become all too familiar. Most players quickly left and returned to the regular 2D graphics, and not without reason. The concept was great - a headset that puts screens up your eyes and dive into a full 3D world. The drawbacks? Heavy Equipment, nausea, feeling of not having a real movement, and very primitive computers handling the heavy lifting.
The most common machines found in arcades VR in the 90's was driven by an Amiga 3000, and was too limited to be anything but a novelty. Several attempts to revive the concept, but with the intrusiveness of even thinner helmet and little or no real support software, they never took.
