10. ACCIDENTAL INPUT PREVENTION AND PALM DETECTION


 


ACCIDENTAL INPUT:


You can prevent accidental inputs that happen from the touchpad when you are typing by enabling the Option "Ignore accidental input" in Trackpad prefpane at System preferences. 


 


Customization:


You can configure accidental input with the following plist options. Located at IOKitPersonalities->Smart-Pad->Preferences->Keyboard in the plist.


  1. TriggerAccInputForKeyPressCount (Value 0 - 10) : Sets the number of key presses needed to trigger accidental input. 

  2. TimeOutEnablesTPadAfterAccInput (Value 0 - 5000) : Sets the timeout for enabling the touchpad back when it was disabled for accidental input.

  3. TapEnablesTPadFromAccInput (Yes/No) : Allows to enables touchpad back when it was disabled by accidental input using a single finger tap gesture instead of waiting for timeout.

PALM DETECTION:


You can also enable/disable Palm detection which can be customized for the pressure and width of the palm by editing plist options from "Others" section of the touchpad plist. Default its enabled and configured to the best values found by the testers in beta testing. If you have problem disable this and PM me for support.


 

Customization:

You can configure palm detection with the following plist options. Located at IOKitPersonalities->Smart-Pad->Preferences->Others in the plist.


  1. PalmDetection (Yes/No) : Enables/Disables palm detection.

  2. PalmCheckMinPressure (Value 0 - 255) : Sets the minimum pressure needed to identify the touch as palm. 

  3. PalmCheckMinWidth (Value 0 - 15) : Sets the minimum width needed to identify the touch as palm.

12. CUSTOMIZATION OF FEATURES
 
We can customize the touchpad features by the editing "info.plist" file located inside the kext (ApplePS2SmpartTouchpad.kext/Contents/). In the plist, go to the section "IOKitPersonalities->Smart-Pad->Preferences" and edit the value of the feature like you want.
 
NOTE: You need to install the kext again after editing the plist. 
Values for boolean controlled features: Yes/No if you use Xcode/Plist editor (or)

true/false if you use Text editor for editing the plist.

 

  • SleepInitDelay: Sets the delay after sleep before enabling the touchpad. Its needed for some touchpads as they fail if we try to enable immediately after sleep because they might be not ready yet. Default value is 1500 ms.

14. Support for Asus Keyboard backlight with Idle Auto on/off:
My driver supports Asus keyboard backlight control using Fn keys mode in keyboard and Idle Auto on/off which can be enabled from touchpad plist keyboard section.
 
Following are the options that controls and enables Asus Keyboard backlight:
Set the entry "EnableAsusKBacklightSupport" to Yes for enabling keyboard backlight controls in F3 and F4 by default. 
Set the entry "AsusKBacklightHas16Levels" to Yes for enabling 16 keyboard backlight levels. 
Set the entry "EnableAsusKBacklightAutoOff" to Yes for enabling keyboard backlight Auto on/off after idle timeout .
Set the entry "AsusKBacklightAutoOffTimeOut" to your required timeout value in milli seconds for enabling keyboard backlight Auto off after idle timeout. Default timeout is 10 sec (10000ms).
 
You also need to use the following patches in DSDT:
 Add the following methods to your ATKD device section in DSDT (or) use the attached patch files in DSDT editor.

 

NOTE: Some systems may need additional tweaking depending on their DSDT.

NOTE 2: Some notebooks might have "SBRG" instead of "LPCB" or something different. So, try to check the method “SLKB” in your DSDT for the the following line values and modify â€œ^^PCI0.LPCB.EC0.WRAM (0xxxx, Local1)”.
