The SimpleHapticsController is an API provided by Microsoft for developers to implement haptic feedback in Windows applications. However, the API itself is not specific to touchpad support; instead, it is designed to work with a variety of input devices that support haptic feedback, such as game controllers, touchscreens, and touchpads.

Verify that the target device, such as a touchpad, supports haptic feedback and is compatible with the SimpleHapticsController API. Not all touchpads might have haptic feedback capabilities.

您好，我这需要做一个touchpad（当前通过BLE连接），请问怎么可以让系统识别到我的触摸板支持振动，我使用VibrationDevice.FindAllAsync接口返回的是null，touchapd配置了Simple Haptic Controller描述符。

Hi.

您可以尝试使用Simple Haptic Controller的UUID来查找设备，然后使用VibrationDevice.FromIdAsync方法来获取设备实例。如果您的设备支持振动，那么您应该能够获取到设备实例。如果您仍然无法获取设备实例，您可以尝试检查设备是否已正确连接并且已启用振动功能。

Hope the information is helpful.

这边按照你的方式获取的实例还是null,。这边是通过蓝牙连接的，除了设备端添加了Simple Haptic Controller描述符没有做其它任何处理，windows下使用的是默认驱动。

var result = await VibrationDevice.RequestAccessAsync();

if (result == VibrationAccessStatus.Allowed)
{
	var device = await VibrationDevice.FromIdAsync("HID\\{00001812-0000-1000-8000-00805F9B34FB}_DEV_VID&021915_PID&EEEE_REV&0001_C62E7917AD23\\9&429E206&0&0000");

	if(device != null)
	{
		var simpleHapticsController = device.SimpleHapticsController;
		var feedbackType = simpleHapticsController.SupportedFeedback.FirstOrDefault(feedback => feedback.Waveform == KnownSimpleHapticsControllerWaveforms.Press);
		if (feedbackType != null)
		{
			simpleHapticsController.SendHapticFeedback(feedbackType);
		}
   }
}

hi,

我按照你的方式返回的实例是null，这边使用的触摸板是ble连接，设备端只是描述符添加了Simple Haptic Controller，系统端没有做任何处理。这边想问下，系统确认设备支不支持振动是根据设备端有没有Simple Haptic Controller判断的还是其它的？

下面是我的测试code:

var result = await VibrationDevice.RequestAccessAsync();

if (result == VibrationAccessStatus.Allowed)
{
	var device = await VibrationDevice.FromIdAsync("HID\\{00001812-0000-1000-8000-00805F9B34FB}_DEV_VID&021915_PID&EEEE_REV&0001_C62E7917AD23\\9&429E206&0&0000");

	if(device != null)
	{
		var simpleHapticsController = device.SimpleHapticsController;
		var feedbackType = simpleHapticsController.SupportedFeedback.FirstOrDefault(feedback => feedback.Waveform == KnownSimpleHapticsControllerWaveforms.Press);
		if (feedbackType != null)
		{
			simpleHapticsController.SendHapticFeedback(feedbackType);
		}
   }
}
