Although I really haven’t been looking, I don’t think I’ve seen any iPhone applications that use multi-touch for 3D navigation, so I thought I’d see if I could come up with a simple mapping suitable for navigation in E15, effectively turning the iPhone into a device for remote navigation of 3D space. My initial set of mappings used the pinching gesture to navigate in the z direction, and parallel two-fingered gestures for rotation about the x and y axes.
