INTRODUCTION
Virtual Keyboard is just another example of today’s
computer trend of ‘smaller and faster’. Computing is now not limited
to desktops and laptops, it has found its way into mobile devices like
palm tops and even cell phones. But what has not changed for the last
50 or so odd years is the input device, the good old QWERTY
keyboard and the virtual keyboard technology is latest development.
The new virtual keyboard technology uses sensor technology
and artificial intelligence to let users work on any surface as if it were
a keyboard. Virtual Keyboards lets you easily create multilingual text
content on almost any existing platform and output it directly to PDAs
or even web pages. Virtual Keyboard, being a small, handy, welldesigned
and easy to use application, turns into a perfect solution for
cross platform multilingual text input.
QWERTY KEYBOARDS
Inside the keyboard
The processor in a keyboard has to understand several things
that are important to the utility of the keyboard, such as:
• Position of the key in the key matrix.
• The amount of bounce and how to filter it.
• The speed at which to transmit the typematics.
DIFFERENT TYPES
Keyboards have changed very little in layout since their
introduction. In fact, the most common change has simply been the
natural evolution of adding more keys that provide additional
functionality.
The most common keyboards are:
• 101-key Enhanced keyboard
• 104-key Windows keyboard
• 82-key Apple standard keyboard
• 108-key Apple Extended keyboard
Portable computers such as laptops quite often have custom
keyboards that have slightly different key arrangements than a
standard keyboard. Also, many system manufacturers add specialty
buttons to the standard layout. A typical keyboard has four basic types
of keys:
• Typing keys
• Numeric keypad
• Function keys
• Control keys
