I would prefer buttons instead of swipes
I took your idea on board and had a bit of a brainstorm. So in addition to swipe and tilt there could be:
- D-Pad (floating?). Can control horiz and vert rotation, or just horiz if tilt is enabled
- touching left vs right side of screen rotates the view left or right. Possibly the distance from the center dictates the speed? Probably requires tilt mode for vertical movement.
- tapping on the screen to send the view straight to that position. Holding finger down will cause the view to continue seeking in that direction at a speed relative to the distance from the center of the screen.
Does any of that sound anything like what you had in mind?
