Soft input panel
The Soft Input Panel (also known as SIP) is a special on-screen input method for devices that do not have standard keyboards . SIP is generally used in Microsoft Pocket PCs and tablets that do not have their own keyboard.
A similar panel is integrated in the Microsoft Windows operating system, which is displayed on the screen as Microsoft Active Accessibility (MSAA). It also includes the option of changing the layout in relation to the keyboard language and key assignment required.
The panel used by Microsoft Corporation was patented on November 15, 2004 at the US Patent Office under patent number 6,819,315.
Procedure
The input of user data takes place with the help of a graphical window environment. A touch-sensitive display screen is used to display images and track user activity. It is a management component that creates a connection from the graphical environment to an input field window that is displayed on the screen.
When the user touches the screen at the input environment, this input calls up the function of the management component and the corresponding input information is adopted like a conventional key press.
The management component then transmits the user data back to the graphical window environment as a message, an application program receiving it and displaying the message as if the corresponding data had been generated using a hardware input device (keyboard).
