According to UploadVR, Google has filed a patent application for motorized VR walking shoes. Apparently, Google is trying to tackle the issue of VR "playspaces" requiring large indoor areas or expensive, bulky hardware to be effective. By adding physical feedback to the "infinite redirected walking" visual illusion some approaches already uses, Google seems to think that realistic VR spaces could be simulated in reasonably sized rooms.
As you’re walking towards the edge of the room, the motors in the shoes will activate in the opposite direction when your feet touch the ground. Until recently, the main approach to physically walking through large virtual environments has been omnidirectional treadmills (ODTs) such as Kat Walk Mini or Omni. ODTs are pretty great at providing a true feeling of walking, but their sheer size means they are expensive both to build and to ship. Many people wouldn’t be able to fit them through their doors, requiring “assemble on delivery” designs that are even more complex and costly. A much more simple approach to VR shoes is that of the recently successful Cybershoes Kickstarter. Cybershoes approach is to have the player seated on a bar stool like chair and slide along a slippery surface with slippery shoes. Very simple rollers transmit movement data back to the PC, but they are not motorized in any way. The main advantage of Cybershoes is its significantly lower cost compared to alternatives. The disadvantage of the Cybershoes, and the main problem Google’s approach seems to be tackling is that it only works seated.
