If you don't have a multitouch device you still can test multitouch gestures using one the following methods:

• StandardInput has a fake touch simulator when you hold ALT and click.
• If you have an iOS, Android, Windows Phone or Windows RT device you can use TUIOInput and an app on your device to remotely send touch input.
  • TuioPad on iOS.
  • TUIODroid on Android.
  • FreeTouch4WP on Windows Phone.
  • Need a link for a Windows Store app.
• If you want to test Windows touch you can use touchproxy to convert TUIO messages to touches.
