Virtual Reality, 3D Movies And Cheap 3D Headsets - Part 2 How?

The big question is how much should you pay to watch 3D movies.

Watching 3D Movies at the Cinema

The way most people watch 3D Movies is at the Cinema using purchase Polarising Glasses.  The best 3D movie I have seen at the cinema is:

The system works pretty well as the left and right eye video images are projected at the same time, but the polarised lens only allow each eye to see the image with its polarisation.  This is a vast improvement on the old technology of projecting the movie in two different colours and audiences having to wear coloured glasses with matching colours for each eye.

The beauty of the polarised approach for mass audiences, is that if your eyes get tired and you take the glasses off you can still watch the movie, although it appears a little blurred.

Watching 3D Movies on the Television

In recent years new High Definition 3D Televisions have become available.  These also use special glasses which are called 'shutter glasses'.  With these glasses the left and right eye pieces are electronically flickered, so that the left eye sees the 'left image' and the right eye sees nothing and vis versa.  This is done at such a speed that the slow human eye and brain sees two different images and combines then in a single stereo picture in the brains visual cortex.  This is also a clever system but expensive and requiring specialist equipment.

Watching 3D Movies on the Google Cardboard 3D Headset

Google mapped onto a very old technology with the release of the cardboard 3D headset.

As I mentioned in my previous entry, this is based on the simple principle of taking two photos on a camera at the same time using lenses which are set human eye distance apart, and they showing them with a viewer in the same manner.  The human brains visual cortex then stitches the two slightly different images together and produces the requires 3D perspective.

If you have 20/20 vision and want to dabble cheaply in 3D Video viewing then there are a huge number of these cardboard 3D Virtual Reality headsets available.
