History of Screen Keyboard

by admin

Screen Keyboard is a utility that displays a virtual keyboard which is a software component that allows a user to enter characters. Screen Keyboard can usually be operated with multiple input devices, which may include an actual keyboard, a computer mouse, a headmouse, and an eyemouse. Besides providing a minimum level of functionality for some people with mobility impairments, Screen Keyboard can also help people who do not know how to type. Another major use for an on-screen keyboard is for bi- or multi-lingual users, who continually need to switch between different character sets or alphabets. Although hardware keyboards are available with dual layouts (for example Cyrillic/Latin letters in various national layouts), the on-screen keyboard provides a handy substitute while working at different stations or on laptops, which seldom come with dual layouts.

Screen Keyboard displays the following types of keyboards:

* Composer Keyboards enable you to compose text. To type alphanumeric characters, you select the characters on the composer keyboard.

* Dynamic Keyboards reflect the applications that are currently running on the desktop. For example, On-Screen Keyboard generates dynamic keyboards that contain keys to represent the applications that are running on your desktop or the menus that are contained in an application

The standard on-screen keyboard utility on most Windows systems allows hot-key switching between layouts from the physical keyboard (typically alt-shift but this is user configurable), simultaneously changing both the hardware and the software keyboard layout. In addition, a symbol in the sys-tray alerts the user to the currently active layout.

Virtual keyboards are also used as features of emulation software for systems that have fewer buttons than a computer keyboard would have. On devices such as personal digital assistants or touchscreen equipped cell phones it is common for the user to input text by tapping a virtual keyboard built into the operating system of the device.

Virtual keyboards can be categorized by the following aspects:

  • physical keyboards with distinct keys comprising electronically changeable displays integrated in the keypads
  • virtual keyboards with touchscreen keyboard layouts or sensing areas
  • optically projected keyboard layouts or similar arrangements of “keys” or sensing areas
  • optically detected human hand and finger motions
  • Screen-keyboards to allow input from a variety of input devices, such as a computer mouse, switch or other assistive technology device.

Many on-screen keyboards can be customized. Extra keys can be added to provide whole words or sentences or ‘macro’ scripts that perform a function such as turning on a lamp or shutting down the computer. Keys can even link to extra ‘pages’ of the keyboard that provide whole new layouts of custom-made keys.

The software works by analysing your high frequency words and providing suggestions as you type the first one or two letters, or even as you complete the previous word. This can be of enormous benefit to Screen Keyboard users as the number of virtual keystrokes saved cuts down on physical exertion and greatly accelerates the overall typing rate.

An Screen Keyboard is alternative that is truly accessible. Besides, having a screen keyboard can come in very handy. Whatever the real motivation might be, this is a great alternative to the out of the box options that come with most operating systems.

Screen Keyboard overview

by admin

A Screen Keyboard is Windows based computer program designed to run on touchscreen computers and monitors. Since touchscreen computers do not normally have a physical keyboard, Screen Keyboard was designed to be a software keyboard which is displayed on touch screen and has functions like a regular keyboard without any physical devices. It is just like any normal keyboard except that you touch the keys on the screen. It will work with any Windows programs running on the computer.
The On-Screen Keyboard can be manipulated by the mouse or other pointing devices and can be configured in three layouts;
* 101 keys display (standard keyboard)
* 102 keys display (an extra backslash)
* 106 keys display (extra characters useful for typing Japanese).
There are many different keyboard layouts, all trying to help users input text as quickly and hassle-free as possible. Most of them are using screen keyboard in different kinds such as: Kiosk, POS systems, hospital terminals, industrial systems, smart phones, etc. with a touch screen.
The virtual keyboard can be launched at Start-up of the computer so it is available as soon as the Windows desktop is displayed. It will display a small computer icon in the bottom right corner of the desktop. Touching this icon at any time will display the full keyboard. Touching it again, will hide the full keyboard
