A soft keyboard sometimes called on screen keyboard or software keyboard is a system which replaces the hardware keyboard on a computing device with an on-screen image map. Soft and compatible keyboards are typically used to enable input on a hand-held device so that a keyboard doesn't have to be carried with it.

These kind of keyboards can usually be moved and resized, and usually can allow any input that the hardware version does. Apart from that, other features such as speech synthesis or word completion or prediction, may be included. A soft keyboard is perhaps the most common type of virtual keyboards.

Although there have been a number of portable keyboards and keyboard alternatives developed for handheld devices, they have often been awkward and error-prone. With a soft keyboard, you can enter data by tapping keys on the keyboard display, generally with a stylus , so that accuracy depends only on hitting the right key.

Some soft keyboards comprise programs that recognize the likelihood of certain keystrokes, so that they can choose the most likely choice when a keystroke is ambiguous. Soft and compatible keyboards are typically used as an on-screen input scheme in devices with no physical keyboard, where there is no room for one, such as a tablet or touch screen equipped mobile phone or pocket computer

Virtual keyboards are also used as features of emulation for systems that have fewer buttons than a computer keyboard would have. For people who are not able to use a regular keyboard, these soft and compatible keyboards allow input through a variety of means, including mouse or trackball  control, touch screen , and head-pointing devices.

These keyboards optically detects and analysis human hand and finger motions and interprets them as operations on a physically non-existent input device like a surface having painted keys. The performance of these new virtual software keyboards is highly customizable. Assign unique sounds to a group of keys, set commands and macros, and use pen gestures instead of the Shift key enable fast typing with better feedback. For more visit www.global-emarketing.com
