			The best results seem to be obtained when the player keeps one foot stationary while stepping. There is, however, no way to enforce this and even with reminders to the player, it’s easy to forget to do this. Nausea can occur if the footing is not maintained.

			This locomotion style also seems to encourage drift from the center of the play space. Eventually the player ends up near the edge of the playspace where they can no longer take a step. This causes a break in immersion as well as frustration.

			The simple implementation described above also doesn’t lend itself to easy turning. In order to change direction, the player must return to the origin, reorient their body, and then step in the correct direction. This was the primary cause of players losing their anchored foot. Possible Improvements To address some of the issues above, a number of improvements can be made to the implementation described above. To address the cumbersome change in direction, it may be possible to incorporate the change in rotation of the head into the direction of travel.

			To address the variability of the tolerances to nausea, it may be possible to allow players to tune the locomotion parameters to something that feels the most correct. This includes the threshold distance, the max speed, and the gain applied to the lean displacement when calculating the velocity.

			The mechanics of Lean-to-Move are simple. The player initiates the movement by pressing the trigger. The system then stores the location of the head when the trigger was pressed as the origin of movement.

			Next, the system waits for the player to lean or move outside of the threshold region. Once the player breaches this radius, the distance between the head and the wall of the threshold is used to compute the player’s velocity.

			===Advantages===
			Lean-to-Move helps to mitigate nausea in a similar way to other locomotion strategies being deployed today. One major advantage of Lean-to-Move is that it frees up the player’s hands to be able to do whatever the game requires. In the FPS setting, for instance, a player can more naturally wield their weapon while moving around. Lean-to-Move also has a low activity overhead, meaning that players can use it for longer without experiencing fatigue.
