Touch Gesture Icons

For example, the double-finger-double-tap a coalesced double-ring is good enough, there is no need of hand on the icon. Similarly for triple-tap three rings coalesced together is enough, drop the hand.
'Press and hold' could be done with the icon you've for 'hold timer' -- without the hand of course. For left, right, up and down swipes something else is required. Hand is terrible while arrows alone won't cut it. We also need icons to suggest typing(keyboard) mode or doodling(free hand) mode on touch screens.
However, it's unlikely that people would recognise they are expected to gesture without some context - the clearest way to indicate the correct context is with the hand.
The hand is providing a necessary function here - although I agree it might be a bit heavy and that it will be less necessary once you've established the context.
The swipe-ups should have the hand off to one side so the arrows can be seen more clearly.
IMO most of these would be better with just a finger or fingers.
We have no iconography. We have no language. It must be representative to actually get people to understand what you want them to do. Iconography can come later, when people actually understand that swiping is a thing you do with your finger. This is at least pretty clear.
If you zoom out to 50%, that's about how big I would expect them to be on a phone, and some of the gestures (especially tap vs. hold) start to blend together.
As a suggestion, perhaps the relative sizes between the hands and the signs could be reconsidered, and a more abstract level of representation of the hand could be thought of.
should be possible
This one needs l10n variants. Haven't you seen Inglourious Basterds?
