Digital Keyboard

A new concept of keyboard working on it .. This type of keyboard will have an android OS..It will support more than 10 languages that can be written or are being used just by single click.
The technology commences to have holographic tech attached which can make any surface as an interactive keyboard.

Without your computer keyboard, whether it's part of a desktop or a laptop, it might've been fairly difficult to get to this article. Sure, maybe you've bookmarked the Web site and you used your mouse to click around between several links, but most of the time, you probably type the Web site address into your browser to get here. Most of us with personal computers use a keyboard almost every day to compose e-mails, type out word processing documents, visit Web sites and perform searches. And as easy as it may seem, typing is a skill we have to learn and practice in order to perform properly. Most students take typing classes as early as elementary school, and word processing is one of the most common skills listed on a job-seeker's resume.

Without keyboards, communicating between family, friends and businesses would be a much less streamlined affair. Today, even smartphones come equipped with smaller keyboards. Phones that are more focused on e-mail and text messaging, like the BlackBerry or several of the slider phones, offer these as a more straightforward way of typing out text. On a typical cell phone with a three-by-four numeric keypad, for instance, where at least three letters are assigned to a number, you often have to punch through each key several times to get one word on the screen. Some people are remarkably adept at this -- just watch some people on a train or at the airport rifle through several text messages in a matter of no time -- but for some, the act is cumbersome and takes far too long. Miniature keyboards, however, attempt to solve that problem by giving users a complete QWERTY setup to type e-mails, text messages and reminders.
       

When you type on a virtual laser keyboard, there aren't any switches involved. In fact, there aren't any mechanical moving parts at all. The device projects the image of a QWERTY keyboard onto a flat, non-reflective surface using a red diode laser. The laser, similar to the kind you see on those cheap laser pointers people wave at rock concerts, shines through a Diffractive Optical Element (DOE), which is simply a tiny image of the keyboard. The DOE, along with special optical lenses, expands the image to a usable size and projects it onto a surface.

But a simple image of a keyboard won't get you anywhere -- something needs to analyze the information you type in. Situated near the bottom of the device is an infrared (IR) laser diode, which shoots out a thin plane of infrared light. The plane, which is invisible and runs parallel to the surface, rests only millimeters above the image of the keyboard. When you start typing, you pass your fingers through certain areas of the infrared light. A CMOS (complimentary metal-oxide semiconductor) images your finger's position within the area of the keyboard, and a special sensor chip called a Virtual Interface Processing Core analyzes the location of the intended keystroke. The device then sends this information to the computer receiving the commands.
But there is a catch .... You can not just start typing anywhere you feel like and expect the keyboard to work properly . It requires a flat surface and also an opaque one to function properly. So there are some constraints attached to it but still they can be very convenient and handy .
