Microsoft recently filed patents with the U.S Patent and Trademark Office for a virtual reality mat. Within the patent documents, Microsoft referred to the concept as a “virtual reality floor mat activity region”.
The virtual reality mat could have the potential to be integrated with technology that would compliment a VR headset, like integrated "fiducial markers," or "spatially distributed pressure sensors." This could allow for the user's location on the mat to be accurately tracked and in turn used in virtual reality. In the patent, Microsoft also states that "vibration devices" could be used in the mat.
The mat could be used as a complementary piece of hardware that works well with VR headsets. The technology could help the functionality of headsets, as well as provide a more immersive experience.
