Abstract: Methods, systems, and devices for automatically evaluating a martial arts move are described. The method may include identifying a distance between a target and a sensor coupled with a user and receiving motion data from the sensor. The motion data may include linear acceleration data and rotation data. The method may further include calculating, based on the distance and the linear acceleration data, an end point in three-dimensional space of the martial arts move and determining whether the user made contact with the target based on a comparison between the end point and a three-dimensional representant of the target. The method may further include determining a rotational characteristic of the move and comparing the rotational characteristic with a stored model of the move. The method may further include evaluating the move based on whether the user made contact with the target and the comparison of the rotational characteristic.
