Touchscreen keyboard softwareWhat is touch screen? A touch screen is a computer display screen that is also an input device. The screens are sensitive to pressure; a user interacts with the computer by touching buttons or keys on the screen. Touchscreen monitors have become more and more commonplace as their price has steadily dropped over the past decade. Touchscreens are popular in heavy industry and in other situations, such as museum displays or room automation, where keyboard and mouse systems do not allow a satisfactory, intuitive, rapid, or accurate interaction by the user with the display's content. The development of multipoint touchscreens facilitated the tracking of more than one finger on the screen, thus operations that require more than one finger are possible. These devices also allow multiple users to interact with the touchscreen simultaneously. Multi-touch allows the user to interact with the device by placing two or more fingers directly onto the surface of the screen.
A dual-touchscreen is a computer display setup which utilizes two screens - either or both of which could be touch-capable - in order to display both elements of the computer's graphical user interface and virtualized implementations of common input devices, including touch screen keyboards. Usually, in a dual-touchscreen computer or computing device, the most persistent GUI elements and functions are displayed on one, hand-accessible touch screen (changing with the software application in use) alongside the virtual touchscreen keyboard, while the other, more optically-centric display is used for those user interface elements which are either less or never accessed by user-generated behaviors. |
