Glasses free 3D television is the next big thing companies are working towards as they look to replace the current cumbersome 3D environment with something that adds more than just depth to the viewing experience.
Today’s illusion of depth put out as 3D in most movies is just a small facet of a real three-dimensional viewing experience where a viewer’s perspective on the object changes as it moves around.
Movies today only show a portion of this with the added depth illusion while also forcing upon consumers to wear cumbersome glasses in order to get a clearer picture. Everyone in the theatre gets the same fixed perspective. Things though are set to shift soon as new technological developments have brought glasses free 3D viewing closer to reality.
Holographic imaging is currently the holy grail of television development which will enable the presentation of images with varying perspectives. Even with the fast paced development of new technology that dream still remains a distant possibility but for the time being researchers at MIT have come up with a much simpler solution that will make multiple perspective 3D viewing a reality.
The MIT Media Lab’s Camera Culture group in a paper submitted at the Siggraph computer-graphics conference suggested a new approach towards the realisation of glasses free and multiple perspective 3D viewing.
According to the researchers their Media Lab system named the Tensor Display will make use of multiple layers of LCDs, technology that is widely used in today’s high definition televisions, to create a convincing 3D illusion.
This will do away with the complex hardware required to generate a holographic display while also generating the multiple perspective picture required for true 3D viewing.
According to the paper a refresh rate of 360 hertz will be required.
Flat panels which such refresh rates are currently in development, and are expected to become available soon enough, increasing the possibility of the arrival of glasses free 3D television viewing.
