owkeey, we ‘ve al been slammed with Surface, the cool new technology by Microsoft..( if you haven’t heard about it ’till now, go back to Pluto where you belong !)

Now Ars Technica has written an article where they explain how it works..

“Ars Technica takes a closer look at Microsoft’s new “Surface” tabletop device. Turns out that Surface isn’t actually a touchscreen at all, but uses five cameras located in the table’s base to record movement and touch. ‘The five cameras are near-infrared devices, but that’s not because they are trying to read heat signatures from fingertips (or other body parts) on the table. Instead, it’s because the entire surface of Surface is bathed in light; by illuminating the top of the table, the cameras can easily see when things are placed on it. Shining colored light across the surface of the table would spoil the effect that Microsoft wants, so near-infrared light is used for invisible illumination.’ The whole setup runs on a Core 2 Duo and off-the-shelf hardware, and can handle 52 simultaneous touches.”

This shows a different perspective on Surface!

But in this article, Bill G says he doens’t got one in his home..

I hear you don’t have one in your house. Are you getting one?
Gates: No. There’s a whole thing about (needing) a complete refresh of my home software. When it first was done quite some time ago, almost six, seven years ago, it was very advanced. Every time I come up from a trip, the photos we took are all up on the displays. Any song, any movie. Today, people can say that’s nice and it’s not like wow. We have a tiny bit like the surface (computing) thing in that we have these touch-screen displays. But they are nothing like the surface thing. They are vertical touch-screen displays.
