The reading window disappears because you have entered a complete pronunciation. A character is displayed on top of the Notepad cursor. This character is not part of Notepad, rather it is displayed in another window on top of Notepad and hides the existing characters in Notepad that are beneath. This new window is called the composition window, and the string in it is called the composition string. The composition string is underlined in the display.
Now type "H", "A", "O", "3" to enter another character. Note that the reading window shows up when "H" is typed and disappears when "3" is typed. As shown below, the composition string now contains two characters. Press the left arrow on the keyboard once. The composition cursor moves one character to the left, at the second character you typed. A window appears on top of Notepad as shown below.
This window is called the candidate window. It displays a list of characters or phrases that match the pronunciation that you have typed.
You can select the intended word from the entries in the candidate list. In this example, two candidate characters are available with the same pronunciation. Type "2" to select the second entry. The candidate window now closes, and the composition string is updated with the selected character. This tells the IME that the composition is complete and the string should be sent to the application - Notepad in this example. The underline is gone in the following figure because the two characters shown are part of the text in Notepad.
Launch Notepad. Click the input locale indicator on the Windows taskbar, and select Chinese Taiwan. The indicator display changes to CH to reflect that the new input language is Chinese Taiwan. On the keyboard type "S", then "U".
The small vertical rectangle is the reading window, which displays the current reading string. As shown in the following figure, the reading string has two characters as a result of typing "S" and "U".
Now type "C", "L", and "3" to enter another character. Note that the reading window shows up when "C" is typed and disappears when "3" is typed. Type the down arrow on the keyboard once. The same interface is also used in assistive technology products such as the screen reviewing tool or on-screen keyboard. By supporting TSF, developers can leverage a wide variety of input services so that assistive technology products can access key information more effectively than with the legacy IMMbased solutions.
The techniques introduced in this article are examples that are available today. Developers of Microsoft Windows applications should be aware of these techniques and related variations. In addition to the graphical user interface GUI elements, it is critical for these assistive technology products to get real-time text events and strings in proper timings to effectively translate a user's input in various forms.
With the complexity of the East Asian languages, it is impossible to map all language-specific characters into Western alphabet maps. For this reason, input services were designed to support the complex typing steps. Assistive technology products translate all user interactions between IME and key inputs while the user is typing. The screen reader may transform the UI activities into synthetic speech text-to-speech engine or a refreshable Braille display.
Typically, in East Asian versions of screen reader, the tools need to access both composition strings and alternative candidate strings or hint text explain what is being displayed on screen.
Composition strings appear as text on the line of the edit field as focused typically underlined and alternative candidate text is stored as a list item shown in the IME candidate UI.
The user typed "n, i, h, a, o" for instance, this could be supported by the Chinese screen reader by pronounced "N I 'nii' H A O". User typed "k, o, n, n, n, i, t, i, h, a, comma , o, g, e, n, k, i, d, e, s, u, k, a,? For instance, this could be supported by Japanese screen reader by pronounced "K 'ko' N 'n' N 'ni' T 'chi' H 'ha' 'ten'.
The support may also be installed as part of Microsoft Office XP applications on Microsoft Windows and other down-level operating systems. However, some assistive technology products require access to only the composition string by way of the TSF layer and control the user interaction by using the programmatic interface provided by the framework. For example, a software keyboard may be written to display the candidate text in its UI rather than allow the user to actually access the text though the IME candidate UI.
TSF is a powerful tool to access not only the composition string but also the whole Document Object Model of the target application. Assistive Technology products can still use the older input manager IMM32 for the programmatic access to composition and candidate strings IMMGetCompositionString , although new input services may be available only though the new interface.
