A general term for these is Performance error as the linked journal article mentions. These can be caused by motor difficulties, literal fat fingers, accidental movement or an incorrect assumption of where the virtual cursor will land.
A touch screen specific problem is the offset from where the user presses, and offset could also describe the excessive movement from a first click point that causes a double click to fail.
With induction pens and resistive screens the touch point might be slightly off from where the computer reads the input as a result of calibration; I never have problems with mouse double clicking but on my first Tablet PCs I had to specify a specific double click distance as I noticed it's much easier to click outside the allowed area.
Capcative touch screens generally don't have this problem but due to using your fingers two problems arise; you can't see the touch point anymore, and your exact touch point is offset from where you think you're pressing. You may think you're about to press a button with the tip of your finger, but accidentally touch the next button down with the pad of your finger if they are'nt properly spaced and you aim low on the first button.
There's a fair body of research in HCI in regards to touch screen offsets for pen/touch interactions. A common suggestion is an offset cursor which shows above the pen/finger tip, offset enough that the user can see it even when their input method covers the touch point.
