1. A system that facilitates evaluation of pitching efficiency of a pitch of a baseball by a person, comprising:
- a control component that receives and synchronizes motion data monitored by each of a set of one or more inertial measurement units (IMUs) that are attached to at least the person to create synchronized motion data, wherein the synchronized motion data includes data indicative of one or more of arm speed, arm slot, wrist motion and hand motion during the pitch; and
an analysis component that analyzes the synchronized motion data in connection with a motion standard and generates pitching efficiency feedback based at least in part on the analysis, wherein the pitching efficiency feedback comprises information relating to one or more of grip and ball release including arm slot, wrist motion and hand motion.

Abstract
Systems and methods of motion tracking are disclosed that can be used in connection with sports motion. Such a method can include placing one or more inertial measurement units (IMUs) on at least one of a person or one or more pieces of equipment, recording motion data associated with the at least one of the person or the one or more pieces of equipment, and synchronizing the recorded motion data. The method can also include analyzing the synchronized motion data in connection with a motion standard, and generating feedback based at least in part on the analyzed motion data.

7. A system that facilitates evaluation of pitching consistency by a person, comprising:
-
a control component that;
(i) receives and synchronizes first motion data monitored by each of a set of one or more inertial measurement units (IMUs) that are attached to at least a baseball to create first synchronized motion data, wherein the first synchronized motion data includes data indicative of rotation, velocity or trajectory of the baseball during a first pitch by the person, and (ii) receives and synchronizes second motion data monitored by each of the set of one or more inertial measurement units (IMUs) to create second synchronized motion data, wherein the second synchronized motion data includes data indicative of rotation, velocity or trajectory of the baseball during a second pitch by the person; andan analysis component that compares at least the first synchronized motion data and the second synchronized motion data to generate pitching consistency feedback, wherein the pitching consistency feedback comprises information relating to baseball rotation, velocity or trajectory. - View Dependent Claims (8, 9, 18, 19)
