Walk through with space mouse

I am trying to make a drive by video of a proposed town entry statement. I personally find the controls in the walk through menu to be a little clunky, and it's hard to get a nice smooth video (unless you travel in a straight line). I've tried using constraints, without much luck.

I have a 3DCONNEXION space mouse, wondering if anyone has found a work around that allows you to use the space mouse to control motion for a walk through. (I guess I could record my screen, and make the video that way, but I want to use photoview 360 to render the video)

I've also tried creating the walk through using a motion study animation, by setting key frames and having the camera move between them. It's ok, but still not as smooth, fluid as I'd like.

Anyone have any tips?
