What is 3D Video?


3D video is not an entirely new technology, having been around in the film industry for many decades. However, the technologies that deliver this immersive form of video viewing are improving. New cameras, better viewing glasses, projection systems, software and displays are starting to bring 3D video into its own at the consumer level, enabling new forms of creative expression and imaging. 3D video requires the capture of two images simultaneously, the same way our eyes do. Once captured, this dual imagery must be displayed or projected in a way our eyes and brain can resolve enough to be believable with the assistance of specialized eyewear. New LED-based systems that do not require special glasses show considerable promise, but currently require a very precise viewing angle. Consumer displays and televisions that support 3D technologies began to appear on the markets in 2010.

(1) How might this technology be relevant to the educational sector you know best?

  • 3D televisions have come quite a long way, and the technology is really compelling. It may be some time before there is sufficient content for many educational purposes, and the cost of the required glasses is still high (but boy, do they work!). I can see significant uses in research settings (eg organic chemistry, medical scanning, architecture, math/numerical analysis, and engineering) where the 3rd dimension adds critical information for understanding.- Larry Larry Aug 23, 2010 - shirley.reushle shirley.reushle Aug 29, 2010
  • Larry's comments re applications are correct, but I would temper this with the difficulty of accurate 3D perception with these technologies, i.e. judging depth well enough for any critical information gained to be trusted is much harder. - ralf.muhlberger ralf.muhlberger Sep 1, 2010

(2) What themes are missing from the above description that you think are important?

  • Because the use cases are still mostly in the future, I think this tech is in the far term horizon (4-5 years) before it reaches edu.- Larry Larry Aug 23, 2010
  • Content creation, both in terms of 3D filming and the 3D data visualisation coding. - ralf.muhlberger ralf.muhlberger Sep 1, 2010

(3) What do you see as the potential impact of this technology on teaching, learning, or creative expression?

  • Research is clear that human ability to pattern match is an exceptionally fast way to process complex information. 3D video rendering of live data streams or real-time analysis could reveal insights not possible in other ways -- in high definition.- Larry Larry Aug 23, 2010
