[Q] Unlock screen without touchscreen topic

Hi guys,

I've got a problem. My Nexus 4 fall on the ground, and the touchscreen is broken. The phone works, I can got to the lock screen, but then I cannot selection anything to unlock it. I know the schema to do. Is it possible to change my finger for anything else, like mouse? Or find another solution?
Then I could unlock and try to get something from it.

Thanks
