Hello,
At Imagina 2010 was presented an awesome 3D mouse : Lexip 3DM.
Basically, it is a high-end mouse (1600 to 3600 dpi) with a thumb mini-joystick, and a rocking cradle (front-rear + left-right).
The cradle and the stick can be used for several purposes : 3D navigation on google Earth, running right-forward + leaning right + shooting + keyboard action all in the same time in a FPS, or driving a car in TrackMania for quick examples.
But what has driven me to buy one, except the will to free my WASD keys in WoW, is 3D modeling.
Here is a video explaining how it can interact in 3D softs.
(other purposes demoed in LexipBe3D youtube channel)
Reviews are very satisfied with experience, one even saying that for desktop works, the mouse is much better than an already proven quality product : Logitech MX Revolution.
Well, I admit that it’s not a real revolutionary interface, but it has neat design, is affordable, and could save precious minutes in 3D applications.
Product is sold in 3 versions : Home, Advanced and Pro.
Home is basic (1600 dpi) but no cradle rocking, Advanced has tweakable software (tweak dpi, etc) 3200 dpi and cradle rocking, and Pro got 3600 dpi + a dedicated team to develop special plugins for different applications (currently supporting most of 3D softwares).
Home Advanced can be found at least on Pixmania, but as it’s a growing but still young business, I don’t know how to buy the Pro outside of France.
Although, I’m sure that they could proceed with personal shipping and support.
Official Site (in french, unfortunately)
I will receive my Pro in like 4 days, so I’ll keep you in touch with a short review.
