3DRudder, a VR controller run completely by ones feet. 3DRudder supports complete freedom of movement for strolling and turning, and it facilitates movement along the Z axis, which means it can also be used to fly, but in a very different way than VIRZoom. 3DRudder is all about choreographing feet to kind of dance through VR. Tools like this will be important to business users who will need to navigate VR, but also keep their hands free to perform various tasks in VR, like optimizing layout for a new facility, or writing a comment on a conference booth design.
It may seem a stretch that VR scenarios support so much flying, but for business applications, this is akin to setting a camera position from above a target. If you are building a high rise or examining a new plane, VR’s ability to fly is a cheap alternative to the real-world need to rent a helicopter or deploy a scissor lift — and its a whole lot safer and perhaps more useful because you can practice doing things, or test out ideas, in VR without worrying about the expense of rework. For many consumers, flying is probably the one ability where they feel humankind was most deprived in evolution’s lottery. VR offer an entirely new way to experience personal flight in the safety of one’s game room.
