Google has been
lobbying the U.S. government for changes in wireless policy. While it did not
achieve as much as it wanted in the planning for the upcoming 700 Mhz spectrum
auction in January, it did push for the fact that consumers in the U.S. can buy
any phone and use it on any carrier in the future. Meaning, that when the
Gphone does drop, most likely you'll be able to use it on any carrier you
please. The Google phone will most likely be 3G as well, which means video
conferencing, yea you can't do that with the iPhone. For you iPhones users
though, would this be enough to make you switch?
The Observer of London is reporting that Google might be working with HTC and
mobile/telecom giant Orange to build a Google Mobile Phone, which could
possibly have Google software inside the device, and would be able to do many
of the web tasks smartly. The device, article speculates, could go on sale in
2008. (Of course, we would all have forgotten by then… if it doesn't happen.)
Orange and Google, both declined to comment.
Their plans centre on a branded Google phone, which would probably also carry
Orange's logo. The device would not be revolutionary: manufactured by HTC, a
Taiwanese firm specializing in smart phones and Personal Data Assistants
(PDAs), it might have a screen similar to a video iPod. But it would have
built-in Google software which would dramatically improve on the slow and
cumbersome experience of surfing the web from a mobile handset.

3D Stereoscopic glasses are nothing new. In fact you had them when you were a kid and probably didn't even know it. Remember the ViewMaster™ that showed all the cool Disney characters in full 3d? The ViewMaster™ allowed you to look at two pictures of the same thing taken from a slightly different view point and tricked your brain into seeing one 3d image.
In order to see things in 3D each eye must see a slightly different picture. This is done in the real world by your eyes being spaced apart so each eye has its own slightly different view. The brain then puts the two pictures together to form one 3D image that has depth to it.
Still want to know how do 3D glasses work? Keep reading!
Anaglyphic [ana·glyph·ic /"a-n&-'gli-fik/] adjective -- A stereoscopic motion or still picture in which the right component of a composite image usually red in color is superposed on the left component in a contrasting color to produce a three-dimensional effect when viewed through correspondingly colored filters in the form of spectacles.
The mode of 3D presentation you are most familiar with are the paper glasses with red and blue lenses. The technology behind 3D, or stereoscopic, movies is actually pretty simple. They simply recreate the way humans see normally.
Since your eyes are about two inches apart, they see the same picture from slightly different angles. Your brain then correlates these two images in order to gauge distance. This is called binocular vision - ViewMasters™ and binoculars mimic this process by presenting each eye with a slightly different image.
Now you're learning! Need to know more about how 3D glass work? Read on. The binocular vision system relies on the fact that our two eyes are spaced about 2 inches (5 centimeters) apart. Therefore, each eye sees the world from a slightly different perspective, and the binocular vision system in your brain uses the difference to calculate distance. Your brain has the ability to correlate the images it sees in its two eyes even though they are slightly different.
If you've ever used a ViewMaster™ or a stereoscopic viewer, you have seen your binocular vision system in action. In a View-Master, each eye is presented with an image. Two cameras photograph the same image from slightly different positions to create these images. Your eyes can correlate these images automatically because each eye sees only one of the images.
A 3D film viewed without glasses is a very strange sight and may appear to be out of focus, fuzzy or out of register. The same scene is projected simultaneously from two different angles in two different colors, red and cyan (or blue or green). Here's where those cool glasses come in -- the colored filters separate the two different images so each image only enters one eye. Your brain puts the two pictures back together and now you're dodging a flying meteor!
3D glasses make the movie or television show you're watching look like a 3-D scene that's happening right in front of you. With objects flying off the screen and careening in your direction, and creepy characters reaching out to grab you, wearing 3-D glasses makes you feel like you're a part of the action - not just someone sitting there watching a movie. Considering they have such high entertainment value, you'll be surprised at how amazingly simple 3-D glasses are.

The reason why you wear 3-D glasses in a movie theater is to feed different images into your eyes just like a View-Master does. The screen actually displays two images, and the glasses cause one of the images to enter one eye and the other to enter the other eye. There are two common systems for doing this:
Although the red/green or red/blue system is now mainly used for television 3-D effects, and was used in many older 3-D movies. In this system, two images are displayed on the screen, one in red and the other in blue (or green). The filters on the glasses allow only one image to enter each eye, and your brain does the rest. You cannot really have a color movie when you are using color to provide the separation, so the image quality is not nearly as good as with the polarized system.
allowing only one image to enter each eye.
At Disney World, Universal Studios and other 3-D venues, the preferred method uses polarized lenses because they allow color viewing. Two synchronized projectors project two respective views onto the screen, each with a different polarization. The glasses allow only one of the images into each eye because they contain lenses with different polarization.
each eye because each lens has a different polarization.
