The invention relates to a direction
control system and method. The invention particularly relates to a wearable device comprising a wearable IMU configured to measure a user, a mounting component, and a controller comprising at least one
processing core, at least one memory including
computer program code; the at least one memory and the
computer program code are configured to, with the at least one
processing core, cause the device at least to perform: receiving data from the wearable IMU, the data comprising motion information related to a motion of the user, the motion of the user comprising a
relative motion between a
thumb of the user and a finger of the user, during at least a portion of the motion, a surface of the
thumb contacts a surface of the finger, using a gesture classifier and based at least in part on the motion information, classifying the motion of the user as a candidate gesture, the candidate gesture being at least one of: a left directional motion, a right directional motion, an up directional motion, or a down directional motion, and outputting the classified candidate gesture.
