This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

The InputDeviceCapabilities.firesTouchEvents read-only property returns a Boolean that indicates whether the device dispatches touch events.

You can use this property to detect mouse events that represent an action that may already have been handled by touch event handlers. This doesn't necessarily mean the device is a touch screen. For example, stylus and mouse devices typically generate touch events on mobile browsers.


var boolean = InputDeviceCapabilities.firesTouchEvents


A Boolean


myButton.addEventListener('mousedown', function(e) {
  if (!e.sourceCapabilities.firesTouchEvents)
