BIDI makes LCD touchscreen A PASSE past

1. This is definitely going to be some thing new for most of the readers.....the following article makes the present touchscreen a PASSEE by introducing the BIDI.

2. The BiDi Screen is an example of a new type of I/O device that possesses the ability to both capture images and display them. This thin, bidirectional screen extends the latest trend in LCD devices, which has seen the incorporation of photo-diodes into every display pixel. Using a novel optical masking technique developed at the Media Lab, the BiDi Screen can capture lightfield-like quantities, unlocking a wide array of applications from 3-D gesture interaction with CE devices, to seamless video communication.The BiDi Screen uses a sensor layer, separated by a small distance from a normal LCD display. A mask image is displayed on the LCD. When the bare sensor layer views the world through the mask, information about the distance to objects in front of the screen can be captured and decoded by a computer.

3. This allows a typical LCD screen working by interpreting hand gestures, without touching the screen.This allows viewers to control on-screen objects by waving their arms in the air without touching the screen, let alone a mouse or keyboard.Although users can touch the screen to activate controls on the display but as soon as they lift their finger off the screen, the system can interpret their gestures in the 3-D.

4. "This is a level of interaction that nobody's ever been able to do before," New Scientist quoted Ramesh Raskar at the Massachusetts Institute of Technology Media Lab, as saying.The screen - dubbed BiDi, short for bi-directional - allows users to manipulate or interact with objects on the screen in three dimensions.

5. It will also function as a 3D scanner, he adds. "If you spin an object in front of screen, the software will stitch together a 3D image."The new system uses an array of optical sensors that are arranged behind a grid of liquid crystals, similar to those used in LCD displays. They physically control how much light passes from the display's backlight.In the new system a regular grid of hundreds of pixels spread across the screen use their liquid crystals to create a tiny hole that acts as a pinhole camera lens, focusing an image of the scene in front onto a thin translucent film a few centimetres behind the LCD.

6. Those images are detected by a camera inside BiDi, allowing the device to know what is happening before it.

Y2K Bug!!!!Do u remember the time?

1. I was just wondering about the time when the much-hyped Y2K crisis had come in with a long, sustained roar and went out with a mewl.While the world excogitated dire predictions of massive global infrastructure failures -- everything from elevators to air traffic control systems was rumored to be vulnerable , the specter of a total paralysis of business operations resulting from cascading Y2K failures galvanized organizations into a frenzy of activity. For many CIOs, the unprecedented size and scope of addressing Y2K problems was the biggest project of their careers.

And then it was over. On Dec. 31, 1999, the world held its breath and nothing happened. Jan. 1, 2000 came in just like any other day. There were no major failures to report anywhere.

2. Today after 10 years....I feel the time has just rolled like a ball....so quickly we are a decade ahead of that night....the night that was a wakeup call for every one who felt that there is no need of IT then....the night that showed how heavily we r banked on the IT......

3. Thanks to http://www.computerworld.com for making me remember that.

Google Binged!!!! - My 100th Post

1. For so many days wanting to upload some post but just could'nt find anthing so interesting before I read about this.

2. From the time Bing was introduced and pitted against arch rival Google,there have been talks and forums across proving each others superiority over each other.Now for the first time some one Big has come up with this.....it follows down..please read!!!

3. A Mozilla official today advised Firefox users to the extension that adds Microsoft's Bing to the list of the browser's search engines after Google's CEO downplayed consumers' privacy concerns.

4. Citing a clip from a CNBC broadcast shown below, during which Google chief executive Eric Schmidt discussed online privacy, During the interview, Google chief executive Eric Schmidt was asked: "People are treating Google like their most trusted friend...should they be?" It was Schmidt's answer that motivated Dotzler to show users how to drop Google, Firefox's default search engine, for rival Bing.

"IF YOU HAVE SOMETHING THAT YOU DON'T WANT ANYONE TO KNOW, MAYBE YOU SHOULDN'T BE DOING IT IN THE FIRST PLACE," SCHMIDT TOLD CNBC. "IF YOU REALLY NEED THAT KIND OF PRIVACY, THE REALITY IS THAT SEARCH ENGINES, INCLUDING GOOGLE, DO RETAIN THIS INFORMATION FOR SOME TIME AND IT'S IMPORTANT, FOR EXAMPLE, THAT WE ARE ALL SUBJECT IN THE UNITED STATES TO THE PATRIOT ACT AND IT IS POSSIBLE THAT ALL THAT INFORMATION COULD BE MADE AVAILABLE TO THE AUTHORITIES," ADDED SCHMIDT.

5. Asa Dotzler, Mozilla's director of community development, then on provided a link to the Firefox extension that adds Bing to Firefox's search engine list.

6. Google chief executive Eric Schmidt would be now trying to undo his statement in some form but the arrow has been shot….and the dent on the google is seen……so googler’s Be ware now on!!!!!!
