I see more than one problem with this approach. First, I cringe at the idea of trying to explain this finger manipulation pattern to my mom. Second, placing three fingers from the same hand on the touch screen would block the place on the screen I am trying to magnify/manipulate from my view. Using two hands to perform this task would be very cumbersome on the larger tablets like an iPad (I just tried without putting my ipad down, didn't go so well). Third, there are already use cases where three fingered swipes are used, increasing the possibility of performing the wrong action. Hover is a way of hiding complexity in a design. Eliminating that complexity is the best way to hide it.

No words necessary! > Second, placing three fingers from the same hand on the touch screen would block the place on the screen I am trying to magnify/manipulate from my view. Wrong. Only certain triangular placements will do this and users will easily learn not to do that. Very flat triangles will have the hand off to the side, just as if you were holding a magnifying glass with no handle. With the right hand, you can do this by having the index finger and thumb extended, with the middle finger bent to sit just below and to the right of the index finger, like so: x x x Since your hand is forming a backwards L, less than 1/4th of the magnifier circle is obscured by your hand. There are many other possible positionings which result in an unobscured view of the reticle. EDIT: This gesture would only work on the iPad. The iPhone would be too small to accommodate it.
