Windows Eye Control Registry Key Location

This article provides an overview of where Windows stores the configuration settings for the built-in Eye Control accessibility feature within the Windows Registry. By navigating to the designated registry paths, administrators and advanced users can inspect, modify, or back up specific parameters such as dwell times, cursor control, typing behavior, and hardware integration.

Primary User Configuration Path

The user-specific configuration for the Windows Eye Control feature is primarily stored in the following registry path:

HKEY_CURRENT_USER\Software\Microsoft\EyeControl

Under this key, Windows manages the active preferences and calibration settings for the current user profile. Key values stored in this location typically include:

• DwellTime: Determines the amount of time the user must fixate their gaze on an element before a click or action is triggered.
• EnableMouse: Controls whether the eye-tracking hardware moves and interacts with the mouse cursor.
• EnableKeyboard: Dictates the state of the on-screen Eye Control keyboard.
• Smoothing: Manages gaze smoothing algorithms to prevent cursor jitter.
• ShapeWritingEnabled: Configures whether shape-writing (swiping) is enabled for the eye-gaze keyboard.

System-Wide and Policy Paths

For device-wide configurations, hardware detection parameters, or enterprise policy enforcements, Windows references two additional locations:

1. System Defaults and Hardware State:
   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\EyeControl
   This path maintains global hardware associations, default configuration profiles, and system-level installation parameters for connected eye-tracking peripherals (such as Tobii devices).

2. Group Policy Configurations:
   HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\EyeControl
   If Eye Control settings are managed through Administrative Templates or Mobile Device Management (MDM), enforced policies will be registered in this key.

How to Access the Settings via Regedit

1. Press Win + R, type regedit, and press Enter to open the Registry Editor.
2. Navigate to HKEY_CURRENT_USER\Software\Microsoft\EyeControl using the navigation pane on the left or by pasting the path into the address bar at the top.
3. Modify the desired DWORD or String values according to your configuration requirements.
4. Restart the Eye Control application or sign out and back into Windows for the modifications to take effect.
