solution to detect multi- finger touch position

Hello, i am build platform on PC, not on android or ios, so the function Input.touches doesn’t work. In my project, i put 2 finger on the screen at the same time, I am looking for a solution to get the second touch position, for the moment i only know the first touch position by using function Input.Getmousedown(0) .

i wonder whether there is a solution for doing it on PC platform.

i am stuck in the problem for many days, any help or suggestion is appreciated, thanks in advance!

If you have access to a mobile device with a touch screen, you can use Unity remote (http://docs.unity3d.com/Documentation/Manual/unity-remote.html)

This is what I do to try out mobile apps in Unity.
