I didn't have time to address this yesterday, but Disney has filed a patent for "moving floors". Much like what was seen in the VR fueled film Ready Player One. The major overall point being able to walk infinitely in a finite amount of space. They've broke it down to three different ways. The first using vibration tech to create friction to the user's feet. Allowing the platform to kinda steer the user out of any contact with walls or other users. The other will use rotating disks to influence direction. Each disk will rotate independently or as a whole to avoid obstructions. The final one mentioned is definitely my favorite of the three, & the most like the setup of Ready Player One . It involves magnets on the users shoes & on a treadmill beneath the floor. As the user walks, that moves the magnetic treadmill, allowing the user to walk forever in the same spot. The schematic pics below, give some more ideas, but this will be a major step for Virtual Reality. I can't wait to see if they can make this hit the light of day. I'm sure I'm not the only one that will spend a lot of time with this tech. Anyway, put your thoughts in the comments, like, & share.
