Vitrual Keyboard

A Virtual Keyboard is a software component that allows a user to enter characters. A virtual keyboard can usually be operated with multiple input devices, which may include a touchscreen, an actual computer keyboard and a computer mouse.

On a desktop PC, one purpose of a virtual keyboard is to provide an alternative input mechanism for users with disabilities who cannot use, or do not have access to a physical keyboard. This is the basic thing.

Virtual keyboards can be categorized by the following aspects:

1. Physical keyboards with distinct keys comprising electronically changeable displays integrated in the keypads

2. Virtual keyboards with touchscreen keyboard layouts or sensing areas

3. Optically projected keyboard layouts or similar arrangements of "keys" or sensing areas

4. Optically detected human hand and finger motions

5. Virtual keyboards to allow input from a variety of input devices, such as a computer mouse, switch or other assistive technology device.

An optical virtual keyboard was invented and patented by IBM engineers in 2008. It optically detects and analyses human hand and finger motions and interprets them as operations on a physically non-existent input device like a surface having painted keys. In that way it allows to emulate unlimited types of manually operated input devices such as a mouse or keyboard. All mechanical input units can be replaced by such virtual devices, optimized for the current application and for the user's physiology maintaining speed, simplicity and unambiguity of manual data input.

 

VIRTUAL KEYBOARDS is a keyboard used as a most secure keyboard till now. This keyboard works virtually it is a on screen keyboard. Most of the bank prefer Virtual keyboard because if your system is infected some types of Trojans or key logger etc. so this will help you to protect from it. If you use virtual keyboard the keys which you pressed is not monitored or saved in key loggers.

Virtual keyboards may be used in some cases to reduce the risk of keystroke logging. For example, Westpac’s online banking service uses a virtual keyboard for the password entry, as does TreasuryDirect. It is more difficult for malware to monitor the display and mouse to obtain the data entered via the virtual keyboard, than it is to monitor real keystrokes. However it is possible, for example by recording screenshots at regular intervals or upon each mouse click.
