Abstract: The invention relates to an electronic wearable device designed to detect unintended movement that occurs immediately prior to a firing event of a gun. The wearable device encompasses at least one sensor, such as an accelerometer, a gyroscope and Electromyography (EMG), to detect a flinch movement that can occur prior to the event of a gun being fired. The user or firer can then be provided with real-time feedback on whether a flinch occurred or not during a firing practice. Feedback can be given to the user, in one embodiment, in the form of an audible tone or a vibrating motor in the wearable device.
