Haptics

Tip

This article covers Uno-specific information for Windows.Devices.Haptics namespace. For a full description of the feature and instructions on using it, consult the UWP documentation: https://learn.microsoft.com/en-us/uwp/api/windows.devices.haptics

• The Windows.Devices.Haptics namespace provides classes for accessing and managing vibration devices and haptic feedback.

VibrationDevice

The RequestAccessAsync method is implemented on all platforms and returns Allowed on all platforms, except for Android and Tizen. In case of Android, the android.permission.VIBRATE permission needs to be declared. In case of Tizen, the http://tizen.org/privilege/haptic privilege needs to be declared.

The GetDefaultAsync method is implemented on all platforms and returns null for the unsupported platforms (WPF, GTK).

SimpleHapticsController

The SupportedFeedback property returns the list of supported feedback types for the given platform. In most cases this includes Click and Press.

The following code snippet illustrates the usage of VibrationDevice and SimpleHapticsController:

var result = await VibrationDevice.RequestAccessAsync();
if (result == VibrationAccessStatus.Allowed)
{
    var vibrationDevice = await VibrationDevice.GetDefaultAsync();
    if (vibrationDevice != null)
    {
        var simpleHapticsController = vibrationDevice.SimpleHapticsController;
        var feedbackType = simpleHapticsController.SupportedFeedback.FirstOrDefault(
            feedback => feedback.Waveform == KnownSimpleHapticsControllerWaveforms.Press);
        if (feedbackType != null)
        {
            simpleHapticsController.SendHapticFeedback(feedbackType);
        }
    }
}
