The 3dRudder is a hands-free solution for VR gaming movement. The device sits on the floor with your feet on top of it, and using your feet you control movement inside of games. It works using pressure sensors, so if you move your feet forward slightly you'll move forward. Push backwards a little and you'll move backwards, and so on and so forth. However, it is only to be used while seated and it is not to be stood on. This may sound like a downside, but in reality it'll be handy for those with limited space and so can't make use of room-scale games (not that we PSVR players have such a luxury).
The device has actually been available for a while for PC users, but now 3dRunner is coming to PlayStation VR in partnership with Sony. The company behind the device will also be partnering with numerous developers to implement 3dRudder into their games. According to the press release notes, it is expected that 30 PSVR games will be compatible with 3dRudder upon release with more to follow in the future.
The 3dRudder goes for $99.95 over on the official website, so it's likely we'll see a similar price for the PSVR-compatible model.
