3. What is Keyboard? The set of typewriter-like keys that enables you to enter data into a computer. Computer keyboards are similar to electric-typewriter keyboards but contain additional keys. The keys on computer keyboards are often classified as follows: The set of typewriter-like keys that enables you to enter data into a computer. Computer keyboards are similar to electric-typewriter keyboards but contain additional keys. The keys on computer keyboards are often classified as follows:  Alphanumeric keys -- letters and numbers.  Punctuation keys -- comma, period, semicolon,and so on.  Special keys -- function keys, control keys, arrow keys, Caps Lock key,and so on. The standard layout of letters, number, and punctuation is known as a QWERTY keyboard. The standard layout of letters, number, and punctuation is known as a QWERTY keyboard.

5. What is Virtual Keyboard?  A virtual keyboard consists of a laser that projects an image of a keyboard onto that projects an image of a keyboard onto a flat surface which can then be typed on as if it were actually there. a flat surface which can then be typed on as if it were actually there.

6.  The Virtual Keyboard attaches to handhelds and projects the image of a full-size keyboard onto the surface of the desk where the handheld is placed, allowing the user to input text without a physical keyboard.

7. HOW ITS WORK?

8. Step1 :Template creation (Projection Module) A template of the desired interface is projected onto the adjacent interface surface. The template is produced by illuminating a specially designed,highly efficient holographic optical element with a red diode laser. A template of the desired interface is projected onto the adjacent interface surface. The template is produced by illuminating a specially designed,highly efficient holographic optical element with a red diode laser. Step2 : Reference plane illumination (Micro- illumination Module TM) A infra-red plane of light is generated just above, and parallel to the, interface surface. This light is invisible to the user and hovers a few millimeter above the surface. A infra-red plane of light is generated just above, and parallel to the, interface surface. This light is invisible to the user and hovers a few millimeter above the surface.

9. Step3 :Map reflection coordinates (sensor module) Reflected light from user interaction with the interface surface is passed through an infra-red filter and imaged on to a CMOS image sensor in the sensor module. Reflected light from user interaction with the interface surface is passed through an infra-red filter and imaged on to a CMOS image sensor in the sensor module. Custom hardware embedded in the sensor chip the makes a real-time determination of the location of the reflected light. Custom hardware embedded in the sensor chip the makes a real-time determination of the location of the reflected light. The processing core can track multiple reflection events simultaneously and can thus support both multiple keystrokes and overlapping cursor control inputs.

10. Virtual Keyboard for Pc’s  A keyboard image is projected onto any surface. Touching a key’s image generates a unique electronic signal corresponding to the key’s image that was touched.

11. Virtual keyboard for PDA’s  There are no mechanical moving parts whatsoever in the Virtual Laser Keyboard, it provides a projected image that is the perfect portable input device for PDA’s.

12. Features of Virtual keyboard  About the size of a small cellular phone, (90 x 34 x 24 mm), the VKB enables users to type texts or e- mails as easily as with a ordinary keyboard. Imagine how easy it would be, if you had a proper mobile phone keyboard that fits in your pocket...  VKB's adaptable technology studies the user's finger movements to interpret and record keystrokes.
