This morning I got my always-excellent Cool Tools newsletter, and read about the SpaceNavigator, a 3-D control device. From the newsletter:
With a little practice you can move through and around the model using the mouse and SpaceNavigator, never touching the keyboard. It provides a huge increase in productivity and, frankly, fun. I’m designing an addition to our house and my kids (6 & 8) have learned to fly through the model without my help. Of course you can use it with other 3D applications, like AutoCAD, Rhino and Maya.
It’s been a while since I’ve seen a new input device which apparently works. They’ve got an explanatory Flash video on their site to demonstrate how you use the thing. I wonder if the thing works with Adobe Illustrator or, say, Second Life?
