On-screen keyboard delay
When an external keyboard (e.g. Bluetooth keyboard or barcode scanner which connects as an HID keyboard) is used with a device, the on-screen keyboard is hidden. When the screen is touched, there is a hard-coded delay period of 60 seconds before the on-screen keyboard reappears. Typically, the user selects an input field on the screen and then uses the external keyboard/barcode scanner to enter the data.
This customization enables an OEM to change that delay period. The delay value is read on boot-up and cannot be changed during runtime. The optional customization specifies the delay in seconds with a default value of 60. If the value is set to 0, then the on-screen keyboard is not hidden.
Create a customization answer file using the contents shown in the following code sample.
<?xml version="1.0" encoding="utf-8" ?> <ImageCustomizations xmlns="http://schemas.microsoft.com/embedded/2004/10/ImageUpdate" Name="HWKeyboardActivityInterval" Description="Use to configure the setting for the delay in showing the on-screen keyboard when an external keyboard is connected" Owner="" OwnerType="OEM"> <Static> <Settings> <Setting Name="HWKeyboardActivityInterval" Value="" /> <RegistrySource Type="REG_DWORD" Path="HKEY_LOCAL_MACHINE\Software\Microsoft\Input\HWKeyboardActivityInterval" /> </Settings> </Static> </ImageCustomizations>
Specify an Owner.
Set the value to the required delay between when a user touches the screen of the device, and when the on-screen keyboard appears, in seconds.
- Flash the build containing this customization to a device
- Connect an external Bluetooth keyboard to the device
- Select the input field on the screen via the on-screen keyboard
- Type abc via the on-screen keyboard.
- Type dce via the external keyboard. The on-screen keyboard shrinks from the screen.
- Touch the screen again and confirm the on-screen keyboard remains hidden until the specified delay expires.
