The 3D Vision Glasses – Up Close and Personal

June 17th, 2009 · No Comments · GeForce 3D Vision

The wireless shutter glasses are just one part of the Geforce 3D Vision, the other major part is a small USB powered “black box” or with other and IR sender box that is used to synchronize the flicker of the glasses with the image available on the screen. What nVidia did very well is designing their shutter glasses without any annoying cables and to actually look cool, especially compared for instance to eDimensional’s solution and other LC-shutter glasses previously made available during the era of the CRT displays.


Besides looking way cooler than before and very similar to normal sunglasses (of course there is more to be done) the glasses are simple and straightforward for usage. You should also note that the “screens” or better described as shutters in front of each eye that are built into the glasses are wider giving you better peripheral vision and making them easier to for wide screen displays such as the 22″ Samsung and ViewSonic available as a bundle with the glasses. You can notice on the right side of the glasses (right in the picture above) the infrared receiver that gets the synchronization signal from the transmitter. And because an infrared signal (part of the light spectrum, normally invisible to the human eye) is being used there is a need for direct line of sight between the receiver and the transmitter. But that isn’t a big problem, because the transmitter box is well enough designed to provide that signal in every possible position and configuration as you’ll see later on…


Looking at the glasses from above you can notice that there is a button and a small LED light indicating the status of the glasses (the right part of the glasses on the picture above). You just need to press the button when you want to use the glasses so that they can be turned on, there is no need to turn them off and you cannot do that by pressing the button again. If the glasses loose the synchronization signal from the transmitter for some time they should turn off automatically to preserve the battery that is being used to power them.


Flipping the glasses on the other side you see the bottom part (the right side from the previous picture is now on the left). Here, just below the power button is a mini USB connector that is being used to charge the internal lithium-ion battery that powers the 3D Vision glasses. And between the charging USB connector and the power on button is the rechargeable battery that provides about 30 to 40 hours use of the glasses on a single charge. The last part of the glasses that you should be aware of is the interchangeable rubber padding that touches your nose when you are wearing the glasses so that they feel comfortable even when wearing them continuously for a few hours. You have three different sizes to choose from so that you can try and see which one fits you best and feels comfortable, but have in mind that the one that best suits you might not be very comfortable to someone else. So if you give the glasses to someone else to try them you might as well offer him to change the rubber padding so that they are relay comfortable, if there is a need to…
