One Finger Zoom - 3D Touch Concept

Still working on a map concept.
It's just an idea on how to use 3D touch (or similar, could be a long touch...) to avoid using two fingers.

here is how it would work:
- Press harder (3D touch) to activate the zoom mode
- The anchor point will now be this area
- Slide up or down to zoom in / out
- Slide left or right to rotate the map.

The first point you pressed will simulate an anchor point, as if it was your second finger.

You can now drink your coffee with a hand and easily find your way with your other hand :)

It's just a concept, tell me what you think about it!
