Some of the 3DConnexion's directional terms I feel are a bit ambiguous, such as Spin and Tilt, which in other contexts could mean rotation in any direction. Zoom is a bit confusing as well, as pan up/down is usually used to 'zoom' in Google Earth. Perhaps there could be an option to display actions in aeronautical terms instead, for those familiar those terms.
