Wireless E-D Glasses - PC - Review

E-D Glasses give games an added dimension to elevate the playing experience

It is all about perception. Games may mimic the effect of three-dimensions with the interplay of light and shows as well as a rotatable camera. But when you are looking at a two-dimensional screen, all you are getting is a perceived notion of three dimensions.

There is a product on the market that splits the image you see, feeds it back to you in different frame rates so that your brain not only reads height and width, but depth as well.

E-D Glasses by eDimensional tricks the mind into seeing the world on you computer with amazing perspective. The test image contains icons that move from the back of the screen to the front, and while you won’t think that the images are coming off the computer monitor, you will almost think that your monitor screen goes back quite a distance.

The concept behind the glasses is known as Stereovision. What is that, and how does this work? Here is an excerpt from the press release.

"Stereovision is actually the normal way almost everyone sees in the real world. Each eye gives a slightly different perspective on the objects viewed and this slight difference provides depth cues to our brain. Objects which are relatively close will shift a larger distance horizontally when viewed from one eye and then switching eyes. Objects which are relatively far away shift a smaller amount. The E-D software and drivers automatically convert the images on your monitor into a left and right perspective. Each image flickers back and forth so fast on your monitor that it is not noticeable to the human eye. Working synergistically with our advanced active glasses, the flickering of each image is precisely timed with flickering of the left and right lens of the glasses, again faster than can be perceived. Thus, stereovision as it pertains to viewing a virtual world means that you have the capability to produce two separate images and that each eye sees only one of the two images."

Got that? Sure it sounds confusing, but these glasses actually work
