We are trying to monitor the Touchpad event like touchpad left click, touchpad right click, or touchpad double tap, etc.
I have a few questions w.r.t. TouchPads.
How to monitor Touchpads events?
How to differentiate between Touchpad events and Mouse events?

Microsoft does not have this type of click event. You can use WM_TOUCH to recognize gestures to monitor touchpad events.

It seems TOUCH events are for the touchscreen only. Touchpad is treated as a mouse input.
"Note that devices such as a touchpad that is common on laptop computers do not support touch if the device merely converts the finger's position and movement as mouse input."Additionally tried the TouchDown, TouchUp, etc. events using a sample application. And observed that the events were triggered for touchscreen only, it was not triggered for the touchpad.
Also, 'MouseEventArgs' parameters do not have any specific parameter which differentiates the touchpad and mouse events.

2025-02-27T15:23:18.83+00:00 Hi @Jiale Xue - MSFT , I understand that there is not Specific Event, is there any parameter which can be monitored to differentiate between touchpad and mouse events.

2025-02-28T06:08:26.8133333+00:00 There is no direct field to specify whether the device is a touchpad. It is possible to infer it through other means, but without high reliability. If your touchpad can get the device name, it may be possible.
