Currently solutions for walking in VR are limited to large and expensive 360-degree treadmills, but Google's new VR shoes patent shows that the tech giant is interested in solving this VR issue. Best described as stationary skates, this Google patent closely resembles roller skates and is described in the patent as "motorized footwear." These VR shoes essentially sync up with a VR headset and allow users to walk anywhere in VR without bumping into any real walls.
This technology may only work in a large space, but the VR shoes actually feature a sensor that brings users back to a "return zone" if they venture beyond a prescribed area. This helps avoid collisions with real-world objects, while still allowing for a freedom of movement in a VR space.
