7/8/2014

Review the settings, dependencies and any notes for the TabletPC-Platform-Input-Core section of the Embedded Core module in the Windows Embedded 8 Standard (Standard 8) module catalog.

These settings include support for touch-screen interfaces through both single and multiple touch points.

Settings

This module includes the following settings.

• MultiTouchEnabled 
• PanningDisabled 
• TouchGate 
• TouchUI 
• TouchUISize 

Notes

Windows Embedded 8 Standard (Standard 8) supports the following Touch scenarios:

• Full Touch, which is the full Windows 8 touch experience.
• Legacy Touch, in which the touch experience is similar to the full Windows 8 touch experience with the following exceptions:
  
  • Windows edge UI values are adjusted to relax edge triggering from 1 pixel to 20 pixels to better accommodate finger swipes from the edges of the display. 
  • There is no Windows touch prediction that provides faster, crisper interaction.
  • There is no ability to swipe to reveal accent keys on the Windows On-Screen keyboard.

Touch Hardware Quality Assurance (THQA) is used to allow or prevent a full touch experience on a device. To have a full touch experience, touch devices must meet the Windows Hardware Certification Requirements. Touch vendors can use Microsoft testing facilities, the Windows Touch Test Lab, to certify that the touch quality of a device meets these certification requirements. A touch input device that complies with the requirements receives a THQA signature in the device firmware to show certification. For more information about the Windows Touch Test Lab, see this MSDN website: http://msdn.microsoft.com/en-us/library/windows/hardware/hh872970.

The following table shows how the Touch experience is based on THQA certification:

Product	THQA certified	Not THQA certified
Standard 8	Full Touch	Legacy Touch
Windows Embedded Enterprise (FES)	Full Touch	Legacy Touch with external monitor* No Touch support with internal monitor*

* Monitors are identified as internal or external via the D3DKMDT_VIDEO_OUTPUT_TECHNOLOGY member of the DXGK_VIDEO_OUTPUT_CAPABILITIES which is reported within the DXGK_CHILD_CAPABILITIES as a result of the DxgkDdiQueryChildRelatios DDI call.

有關 Windows 8 Touch 相關問題，參考了MSDN上的文件，做個簡單的整理如下表：

Product	THQA certified	Not THQA certified
Standard 8	Full Touch	Legacy Touch
Windows Embedded Enterprise (FES)	Full Touch	Legacy Touch with external monitor* No Touch support with internal monitor*

可以發現微軟把 Touch 分成兩種，
1. Full Touch：擁有 Windows 8 使用經驗
2. Legacy Touch：相似於 Full Touch，但是擁有以下的例外
          - 當指頭從螢幕邊緣滑進來的偵測從 1pixel 變成 20 pixels
          - 沒有提供快速、互動式的聯想輸入法
          - 沒有提供語氣加強符號在螢幕小鍵盤中

THQA 認證為微軟所提供，主要是確保 Touch vendor 所提供的 touch 能相容於 Windows。

判斷內部與外部螢幕，由 D3DKMDT_VIDEO_OUTPUT_TECHNOLOGY 的參數所決定，以下有附上相關連結參考。
