The virtual keyboard is an innovation in product software that allows alternative to use of a conventional computer keyboard. Sometimes referred to as a laser keyboard, it provides a simple and effective solution for persons who are unable to operate standard keyboards. Currently, there are several emulation programs on the market today that can be added to any desktop or laptop system and create a virtual keyboard environment.
Loading the software for a virtual keyboard is no different from loading any software package. Once in place, the keyboard can be activated and allowed to reside on the desktop for easy access. When it comes to working the keyboard, different software packages will make use of different input devices. In some cases, the actual keyboard is used to active the virtual component, then the mouse can be used to move over the virtual keys, allowing the user to type by selecting the right keys on the display. This format is often very helpful for persons who are suffering from any condition that limits the mobility of the hands.
Along with operation by the use of a computer mouse, there are a couple of alternative devices that are available with some virtual keyboard software. The headmouse and eyemouse are excellent solutions when body mobility is impeded. Utilizing laser technology, it is possible to operate the virtual keyboard with the use of simple head movements, or even by blinking the eyes.
Hand held devices are also often equipped with a virtual keyboard. In this type of application, the keyboard is usually accessed and manipulated using a stylus that is included with the unit. By simply holding the stylus in one hand, it is possible to draft messages, move through stored documents, and make entries on spreadsheets that are stored on the hard drive. While not quite as user friendly as the virtual keyboard solutions offered for desktop and laptop computers, virtual keyboards loaded onto personal data assistants do eliminate the need to connect a folding keyboard to the PDA in order to work with documents and programs.
