How Microsoft surface configured?

Surface computing is the term for the use of a specialized computer GUI in which traditional GUI elements are replaced by intuitive, everyday objects. Instead of a keyboard and mouse, the user interacts directly with a touch-sensitive screen. It has been said that this more closely replicates the familiar hands-on experience of everyday object manipulation.

1)) Screen:

A diffuser turns the surface's acrylic tabletop into a large horizontal " Multi touch " screen, capable of processing multiple inputs from multiple users. The surface can also recognize objects by their shapes..

 2)) Infrared :

Surface's "machine vision" operates in the near-infrared spectrum, using an 850 nanometer wavelength LED light source aimed at the screen. When objects touch the tabletop, the light reflects back and is picked up by multiple infrared cameras with a net resolution of 1280 * 960.

3)) cpu :

Processor: Core 2 Duo processor
Graphics card : 256MB
Operating system is modified version of Microsoft Vista

4)) Projector :

Microsoft’s Surface uses the same DLP light engine found in many rear-projection HDTVs. The footprint of the visible light screen, at 1024 * 768 pixels , is actually smaller than the invisible overlapping infrared projection to allow for better recognition at the edges of the screen.

Magic Mouse

Magic Mouse — with its low-profile design and seamless top shell — is so sleek and dramatically different, it brings a whole new feel to the way you get around on your Mac.

You can’t help but marvel at its smooth, buttonless appearance. Then you touch it and instantly appreciate how good it feels in your hand. But it’s when you start using Magic Mouse that everything comes together.

The Multi-Touch area covers the top surface of Magic Mouse, and the mouse itself is the button. Scroll in any direction with one finger, swipe through web pages and photos with two, and click and double-click anywhere.

Inside Magic Mouse is a chip that tells it exactly what you want to do. Which means Magic Mouse won’t confuse a scroll with a swipe. It even knows when you’re just resting your hand on it.

laser tracking system :
It tracks with precision on nearly every surface — whether it’s a table at your favorite cafe or the desk in your home office — without the need for a mousepad .



Bluetooth Icon Magic Mouse connects to your Mac via Bluetooth wireless technology, so there’s no wire or separate adapter to worry about. Pair Magic Mouse with your Mac and enjoy a reliable and secure connection up to 33 feet away.

 It is simply awesome gadget By Apple...

Grid computing

When we have to work with a large application with only one is very much difficult task..
To handle such application easily we have to use "GRID COMPUTING".

What it does?
It divides a large application into number of modules, and give each module to a individual computer..and operate each module separately..and at the and give output as a integration of all module..

In short Grid computing deals with the sharing of tasks over number of computers.

To apply grid we have to connect number of computers and have to make a mini which all devices are connect with GRID.
these arrangement can be of three types:

Intragrids:  – Single organizations
                   – No partner integration
                    – A single cluster
Extragrids:  – Multiple organizations
                    – Partner integration
                    – Multiple clusters
Intergrids:  – Many organizations
                   – Multiple partners
                   – Many multiple clusters

Applications for Grid:

•  Bio Informatics applications
        BLAST : Basic Local Alignment Search Tool, is an algorithm for comparing primary biological
                       sequence information

        FASTA : FASTA is a DNA and protein sequence alignment software package

•  High Energy Physics Applications
        LCG (Large Hadron Collider (LHC) Computing Grid) : ALICE-A Large Ion Collider Experiment

•  Weather Modeling and Predicting Ocean Currents
        Weather Prediction

        – Storm, Rain, Surface pressure and Winds
        – Comparing data from sea, ground and air
        – Correlating with previous climate data

•  Disaster Management
        Natural Calamities

        – Flood, Earth Quake, Cyclones Requirements for Disaster Management
        – Timely dissemination of disaster information to user agencies
        – Organize logistics around automated and secure work flow and data base
           Challenges in Disaster Management

•  Aerodynamic Simulations
