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
• 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.

What is Virtual Keyboard?

• A virtual keyboard consists of a laser
• that projects an image of a keyboard onto
• 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

• Step1Template 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.
• 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.

9

• Step3Map 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.
• 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 Pcs

• A keyboard image is projected onto any surface.
  Touching a keys image generates a unique
  electronic signal corresponding to the keys
  image that was touched.

11
Virtual keyboard for PDAs

• 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 PDAs.

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.

Bluetooth Virtual Laser Keyboard

• The Bluetooth Virtual Laser Keyboard comes with a
  self-contained, rechargeable lithium ion battery
  that provides it with an internal power supply,
  so it doesn't need to drain any power. The
  battery lasts several hours, ample time for
  emailing, instant messaging, SMS'ing, typing
  documents or updating your calendar and phone
  book entries.
