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…

Nvidia GeForce 3D Vision Kit

Recently Nvidia is making quite a few new products that are not in their main focus and by that I mean the GPU business. Some of the new interesting products coming out from nVidia are for instance the ION platform or the Tegra, products based on which are just now slowly starting to come out in the market. Actually there is one more interesting solution that was announced a few months back, but just recently became available in Europe – GeForce 3D Vision. These are basically LC shutter glasses (often referred as LCD shutter glasses which is not entirely correct) that are designed to work with a suitable display that can provide at least 100 Hz or higher refresh rate. Now as normal LCD displays cannot provide such a high refresh rate or actually we better use the term frame rate here when talking about LCD displays we are going to need a new type of LCD displays. So Samsung and Viewsonic provided a solution in the form of 22-inch LCD displays with 120Hz refresh rate so that they can be bundled with the 3D Vision glasses to provide the best experience. So far ViewSonic VX2265wm is only available on the American market and the Samsung 2233RZ is available in Europe both bundled with nVidia’s 3D glasses or as a standalone monitors. Apart from these two monitors you can also use the GeForce 3D Vision glasses with a normal CRT display (that can provide high enough refresh rate) if you still have one of these lying around. There is also support for some DLP TV sets and 3D projectors, but these are still not very popular and widely available so the best way is just to get the 22-inch Samsung or Viewsonic LCD display available where you live. By the end of this year other LCD display manufacturers should also start to provide suitable models with high refresh rate, bigger resolution and size, but we will have to wait and see.

With the help of Nvidia GeForce 3D Vision you can start enjoying a way more impressive 3D gaming experience, watch suitable 3D movies and even look at digital photos in 3D. Of course the most interesting and impressive features is the use of the technology for gaming, making most of the new titles and a lot older games a lot more impressive. By utilizing the 3D Stereo shutter glasses you can experience all 3D games in a new way, even games that you can completely finished playing will seem different to you when you’ll be able to see the depth of the 3D world around you. Of course not all games work perfect out of the box, but most of them have built-in profiles and provide information and good enough result by default and then you can tweak them a bit to achieve better results based on your personal preferences. But even if a game doesn’t have a profile there is a high chance it will work fine with some minor tweaking or even without having to do anything special, you just have to try. And the list of games that have serious problems or are not working at all is very small indeed and there is a chance that they may become supported in later updates of the drivers. I’ll tell you some of the games that provide the best results combined with GeForce 3D Vision that you should definitely try if you have the chance to test this 3D Stereo product or even if you buy one yourself. Anyway there is way more to come about Nvidia GeForce 3D Vision and not only about it, so stay tuned for more information… ;)
