1. A method comprising: receiving, at data processing hardware ( 240 ), an inertial measurement ( 232 ) from an inertial measurement sensor ( 230 ) disposed on a user ( 10 ), the user ( 10 ) defining a vertical gravitational axis (V g ) and a forward travel direction (D T ), the user ( 10 ) having a pose (P) defined by a sway angle (θ s ) of the user ( 10 ) relative to the vertical gravitational axis (V g ) and a sway direction (D S ) of the user ( 10 ) relative to the forward travel direction (D T ), the inertial measurement ( 232 ) indicative of a movement of the user ( 10 ) from a first pose (P 1 ) to a second pose (P 2 ) away from the first pose (P 1 ); determining, by the data processing hardware ( 240 ), a movement vector (M) defining the movement of the user ( 10 ) from the first pose (P 1 ) to the second pose (P 2 ) based on the inertial measurement ( 232 ), the movement vector (M) relative to the first pose (P 1 ); determining, by the data processing hardware ( 240 ), whether the movement vector (M) satisfies a threshold movement vector (M T ); and when the movement vector (M) satisfies a threshold movement vector (M T ), instructing, by the data processing hardware ( 240 ), at least one actuator ( 220 ) to apply a feedback response on the user ( 10 ).
