Motional training is achieved by providing a subject with vibrotactile
feedback in response to an attempt by the subject to perform
predetermined motions. In particular, an attempt by the subject to
perform at least one predetermined motion is monitored using sensors,
such as force plates or inertial sensors. The sensor signals indicate
results of the attempt by the subject to perform the at least one
predetermined motion, and a variance between the at least one
predetermined motion and the results of the attempt by the subject to
perform the at least one predetermined motion is determined. Vibrotactile
signals are then sent to the subject by activating one or more actuators
coupled to the subject, where the one or more actuators are spatially
oriented with respect to the subject to indicate one or more directions.
The vibrotactile signals indicate the variance with respect to the one or
more directions.
