I've recently been thinking about what I am calling double or compound walking where you walk with both the joystick and your real body for potentially combined movement speed. I don't have enough room to verify if it works in any games but after I move I have a decently long hallway I could test it in. My thinking is to work around the abysmal stamina in the vr games I've played so far and weirdly slow movement speed.
The holotile would probably need some way to pass its tracking to the game if that was being used though.
