Almost every time we've played around in virtual reality, be it of the Oculus Rift or Gear VR variety, we've had a game controller of some sort in our hands. It's necessary to navigate an environment, pop around and generally have a look about. The folks behind 3DRudder want to take that paddle and put it under your feet. At its simplest, the 3DRudder is an unobtrusive circular platform that replaces a D-pad on the controller. It's about 12 inches across and has a halved sphere underneath. Gyroscopes and accelerometers tucked inside track your movements via the pitch and yaw of your tootsies, and it connects to your computer via USB. According to the developers, the primary use they have in mind is for navigating 3D modeling programs like ZBrush or Maya, freeing your hands to switch brushes or change a tool while using feet to get around the scene you're making.
