Sony has a design for modular, universal active-shutter 3D glasses. The plans were recently spotted
at the U.S. Patent Office. Proprietary LCD shutter glasses remain the most common method of viewing 3D content at home. Manufacturers use infrared and Bluetooth connections and most feature proprietary protocols that can change when a product line receives an update. Considering the high cost, fragility and proprietary nature of OEM 3D glasses, one can see the appeal of an inexpensive, modular, and universal pair.
Sony claims to have miniaturized the receiver modules to the point where eight of them can accommodate most brands of 3D TV. Furthermore, the design is modular allowing the inexpensive receiver module that is replaceable as new systems come to market. The key to glasses' design is programmability. In a manner similar to universal remotes, the glasses synchronize to a 3D TV via a product code or through a USB connection and a web-based app. There does not appear to be any provision for Bluetooth connected active shutter glasses, such as Panasonic's 2012 "RF" 3D glasses.
I have tried both active and passive 3D at home. Last year I settled on a passive 3D TV. The cost, comfort, and compatibility of the glasses was no small part of that decision. Is this concept from Sony a tempting option? Is active shutter 3D already doomed? Or is Sony's new product a solution that will create greater market acceptance of built-in active 3D capability on budget TV sets, computer monitors and projectors?
One problem with 3D televisions is that the glasses they depend on are a bit like the remote controls. They may do their job, but using another manufacturer's device is like fitting the wrong key in a lock. Today, there are programmable remotes available for the price of a sandwich. The Sony 3D glasses described in the patent application are their equivalent. source: gizmag
