A virtual keyboard is a software component that allows a user to enter characters. Designed for anyone with a disability that prevents him or her from typing on a physical computer keyboard. As long as the physically challenged person can control a mouse, trackball, touch screen or other pointing device, this software keyboard allows you to send keystrokes to virtually any Windows application or DOS application that can run within a window.
If you spend a lot of time responding to e-mail or jotting down notes on your mobile computer and find your hardware keyboard awkward or too small, a screen software keyboard may be just the improvement you’ve been seeking. This handy keyboard has keys large enough to be typed with the fingertips.
