Round VR walking rugs
[Philip Lelyveld comment - round rugs are standard for good VR walking experiences. This company is creating premium round rugs designed for VR.]
...24″ and 36″ diameter mat were perfect for standard room sizes. The definable safety zone is considerably larger than the diameter of the mat because it is designed to allow for 1 foot on and one foot off when stepping away from the center of the mat.
The next step was to create a more definable center of the mat which we call the “Home” locator, this was accomplished by using a harder rubber that is taller than the matting itself without creating a catch point or something that could hurt you if you stepped down on it. The choice was a translucent red urethane for the black mat and a translucent blue urethane for the gray mat which were chosen for aesthetics and how well they worked. We are looking at alternatives for the buttons on the final production.
