Haptics

[!TIP] This article covers Uno-specific information for the Windows.Devices.Haptics namespace. For a full description of the feature and instructions on using it, see Windows.Devices.Haptics Namespace.

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

VibrationDevice class

The GetDefaultAsync method is implemented on all platforms and returns null for the unsupported platforms (Skia Desktop).

Platform-specific requirements

Android

For Android, there is one permission you must configure before using this API in your project. To do that, add the following to AndroidManifest.xml:

<uses-permission android:name="android.permission.VIBRATE" />

Tizen

For Tizen, the http://tizen.org/privilege/haptic privilege needs to be declared in tizen-manifest.xml file.

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);
        }
    }
}
