Japanese OS Design Development (Windows Embedded CE 6.0)

1/6/2010

For Japanese, Windows Embedded CE offers a choice of two Input Method Editors (IME) and five Input Methods (IM). All Japanese IMs are implemented as Component Object Model (COM) components and exposed through the input panel component. The Japanese IM implementation in Windows Embedded CE consists of two parts: the Software-based Input Panel subsystem and the IMs. The input panel is responsible for converting non-keyboard input into a keyboard event.

The following table shows the three IMEs that are included in Windows Embedded CE for the Japanese locale.

IME Description

Pocket IME

Compact and customizable. A default and two optional lexical databases are provided, as is a sample customizable UI.

IME 3.1

Provides samples skins and allows you to customize the IME toolbar, candidate window and default composition window. The property dialog boxes, dictionary tool dialog boxes, and the system tray icon support are separated, allowing you to select specific UI functionality for your OS design. Supports portrait and landscape orientation.

TESTIME

Basic; use to create your own IME.

For more information about how to customize the Japanese Pocket IME, see Japanese Pocket IME.

For more information about how to customize the Japanese IME 3.1, see Japanese IME 3.1.

The Japanese Edit Control functionality in Windows Embedded CE allows OEMs to configure editing functionality for an Input Method Editor (IME). Unlike in previous versions of the operating system, where the default level was set to level 3, in Windows CE .NET 4.0 and later the default level of the Japanese Edit Control is set to level 2. OEMs can change the level of Japanese Edit Control functionality by setting a registry key. For more information, see Japanese Edit Control.

In addition to three IMEs, Windows Embedded CE supports a hardware keyboard for a Japanese build, which is a U.S. keyboard with ALT+" equal to VK_KANJI. Windows Embedded CE also provides eight Input Methods (IM) for the Japanese locale. The following table describes the available IMs.

IM Description

Bushu-kensaku

A search by radical engine that enables complex Kanji character selection based on radicals. UI is provided as a sample for customization.

Soukakusu-kensaku

A search by stroke engine that enables complex Kanji character selection based on character strokes. UI is provided as a sample for customization.

Microsoft Kana

An on-screen keyboard that enables input of Hiragana and Katakana directly. This IM is provided as sample code.

Microsoft Roma

An on-screen keyboard that enables input of the Western alphabet. This IM is provided as sample code.

Multibox

A sample UI for Japanese handwriting input that works with IME 3.1 and with Pocket IME. The source code is located in %_WINCEROOT%\Public\Common\Sdk\Samples\Multibox.

All Character IM

A sample IM that enables character input based on a comprehensive character list.

Character Auto Complete (CAC)

A sample UI that works with the handwriting recognition engine. This IM automatically updates a list of possible character candidates with each character stroke that the user draws.

Handwriting Recognizer Engine (HWX)

A handwriting recognition engine for supporting user-drawn ideographs and characters. You can use the Multibox and CAC IM samples to develop an IM for this engine, or create an entirely new UI.

Choosing the date format, gg yy/MM/dd, in Windows Embedded CE results in an Era symbol and a Gregorian calendar year. To display the Era calendar year, which displays years from the current emperor's accession, you must use the gg ee/MM/dd format.

OS Design Information

The following table shows operating system design information for Japanese.

Concept Description

Dependencies

The Japanese IMs that use a soft keyboard (mskana and msroma) require the Software-based Input Panel Driver Catalog item.

Hardware considerations

The Japanese IMs that use a soft keyboard require a touch screen.
