3D screens come in many varieties, but that also means that 3D glasses come in a large variety too, something that Sony is none too pleased about and, thus, intends to change as soon as possible.
Some may think that 3D glasses come in only two forms: with passive polarization and with active shutter mechanisms.
This is true, to some extent, and the passive polarization models are more or less intercompatible, though they don't allow for the same quality as the others.
The active shutter glasses don't work interchangeably though. Each company selling an active 3D display also ships specially designed glasses too.
For gaming monitors from NVIDIA, the 3D Vision platform acts as a sort of common denominator, but that doesn't apply to AMD-powered systems.
Basically, there are too many types of 3D glasses running around the world, so Sony wants to make them all irrelevant.
In a patent application filed with the US Patent and Trademark Office, it defines universal 3D glasses that, in a way, imitate the core concept behind universal remote controls.
Long story short, all types of 3D glasses receivers will be packed into a single piece of eye wear, and it will be possible to calibrate the settings.
For the sake of comparison, normal LCD shutter glasses use proprietary technologies to calibrate the glasses by means of infrared signals sent through a receiver attached to the TV itself. A different method from the all-in-one receiver method proposed by Sony.
According to the filing, 3D glasses are just one potential application of the idea. Helmets, goggles and other headwear will be able to incorporate the lenses and sensors.
By Sony's estimation, it shouldn't take more than eight individual receivers to cover all possible 3D screen implementations. The rest will be done by multiple infrared lenses or an adjustable lens in an eyeglass frame.
