How do you trick a touch pad?

Answer 1

There is no need to "trick" a touchpad. It is capable of only one thing: sensing pressure and tracking the movement of pressure across it's surface. It doesn't care if you use your finger, a pencil, or your cat.

The guy above is an idiot with a prehistoric laptop. Whatever trackpads use to recognize biological material is unknown. Conductive materials alone fail to work. I have discovered that a penny will fool a trackpad but only if your finger is directly touching the top of the penny (using a pencil to guide it won't work, I don't have a clue as to why)
