E-archery: prototype wearable for analyzing archery release

This paper describes a wearable device prototype that utilizes an accelerometer to track hand motion in order to capture an archer's "release" and uses this information to help archers in training sessions where the coach is not present. Release is a critical component of an archer's form and is categorized into either good, bad, or pluck release. This paper aims to provide a data driven approach to train archers, a process that is currently visually detected and manually tracked. 50 samples of each of the three types of release were used to train and validate an classifier that achieved classification recall greater than 90% for all three types.
