I'm with 3dRudder, a French start-up, and we designed a foot-powered 3D mouse that can be used while working Rhino 3D to control camera modes with your feet.
Here’s a quick video: Video Rhino3D with 3dRudder
You can navigate within your 3D designs with effortless movements of your feet on the 3dRudder: dolly in/out, pan, orbit, vertical pan & orbital camera. It frees your hand for design only, it also relieves joints and offers transparent commands (you can change perspective and shape your design at the same time). The device is progressive (the more you push with your feet, the quicker you go, and vice versa) and surprisingly intuitive to control.
It’s very easy to install: basically, once you receive the device, you just need to install the plugin within Rhino3D and you’re ready to work. You can visit our page for more info: click here
I'd like very much to hear your opinion about our solution and listen to any advice you might have.
Thanks for your feedback
