Virtual Keyboard
When entering confidential data (such as a user name and password at an online store) with a normal keyboard, there is always a risk of this data being intercepted by spyware. Such programs record keystrokes and in this way read information that is entered with a normal keyboard. This information is then sent to the intruder through the Internet.
Functions of different keys on the Virtual Keyboard
Caps Lock: This key can be used to enter upper case if the password consists of capital letters.

Disadvantages of a Virtual Keyboard
Tactile Feel
One benefit of a physical keyboard is the ability to feel the keys pushing down. Although this is not necessary, it does help some users determine when a key is struck with an appropriate amount of force. The virtual keyboard does not provide the same tactile feel and can take some adjustment for those composing letters, documents or chatting online.
Space
On a device with enough screen space to accommodate a full size keyboard, it can be difficult to see the document being typed on the screen. A full-size QWERTY keyboard uses a large amount of the screen
space to accommodate two hands while typing. This limits the ability to proofread a document or letter while typing. Only a fraction of the letter or document will be visible above the virtual keyboard.
Dirty Screens
While a physical keyboard can become dirty with crumbs, dust and debris, the screen usually remains clean. When using a virtual keyboard
and touch-screen technology, the screen will inevitably become smudged and dirty. Over time, the device’s screen can become difficult to see and read.
Ergonomics
Using a virtual keyboard on a larger tablet style device can cause ergonomic issues for the user. The device must be propped at an angle
to keep wrists in the proper position for comfortable typing. The user must also look directly down on the screen while typing and this can lead to neck injury or neck fatigue if typing for a long period.
