System for automatic evaluation of martial arts moves

A method of evaluating a martial arts move, comprising:

• identifying a distance between a target and a nine degree of freedom (DOF) sensor coupled with a user;
• receiving motion data from the nine DOF sensor, wherein the motion data comprises three-dimensional linear acceleration data as a function of time and three-dimensional rotation data as a function of time;
• calculating, based at least in part on the distance and the three-dimensional linear acceleration data, an end point in three-dimensional space of the martial arts move;
• determining whether the user made contact with the target based at least in part on a comparison between the end point and a three-dimensional representation of the target;
• calculating, based at least in part on the three-dimensional rotation data, a rotational characteristic of the martial arts move;
• comparing the rotational characteristic of the martial arts move to a stored model gesture corresponding to the martial arts move;
• evaluating the martial arts move based at least in part on whether the user made contact with the target and the comparison of the rotational characteristic;
• and
• transmitting an indication of the evaluation of the martial arts move to a user device.
