1. A method comprising: receiving, at data processing hardware, an inertial measurement from an inertial measurement sensor disposed on a user, the inertial measurement sensor comprising a tri-axial accelerometer and a tri-axial gyroscope, the user defining a vertical gravitational axis and a forward travel direction, the user having a pose defined by a sway angle of the user relative to the vertical gravitational axis and a sway direction of the user relative to the forward travel direction, the inertial measurement indicative of a movement of the user from a first pose to a second pose away from the first pose; determining, by the data processing hardware, a movement vector defining the movement of the user from the first pose to the second pose based on the inertial measurement, the movement vector relative to the first pose; determining, by the data processing hardware, whether the movement vector satisfies a threshold movement vector; and when the movement vector satisfies a threshold movement vector, instructing, by the data processing hardware, at least one actuator to apply a feedback response on the user, the at least one actuator disposed on a band circumscribing a portion of the user, the feedback response comprising at least one force that is substantially opposite and proportional to the movement vector.
