A low-cost omni-directional VR walking platform by thigh supporting and motion estimation

We propose a low-cost omni-directional VR walking platform by thigh supporting and motion estimation. Specifically, this platform supports the thighs of the user to the walking direction, and the user make the stepping motion while leaning to the walking direction. Thereby making it possible to change the center of gravity of the foot sole like an actual walking. Moreover, our platform estimate the foot movement which constrained by thigh supporting part with load cells around the user's thigh, and render to the HMD according to the estimated foot movement. As a result, our platform enables user to make the walking sensation more realistic at low-cost.
