Virtual reality treadmills might become a thing in the future. We have already seen a couple of interesting VR treadmills in the past few months. The PAO is another solution that lets you walk, run, and jump while playing games. It uses sensors and transmitters to capture motion. It can be used with PC, Android, and other platforms.
The PAO is lightweight and easy to assemble. It will let you get a more dynamic VR experience while playing games. You can find out more about it on Kickstarter.
