US12782089 - Firearm simulation device with haptic feedback

There is a need in the firearm training field for a firearm that can analyze the shooter's grip, aim, position, and anything else that could affect a shooter's technique. The invention is designed to monitor the shooter's technique in real-time using motion sensors to determine any movement by the firearm or the shooter. A light based detection system also tracks the shooter's and firearm's movement by detecting the amount of time it takes for light emitted from the device to reflect back to the device. The motion detected is analyzed and converted into a haptic feedback for the device to emit to the user, usually in the form of a vibration or shaking. The shooter can interpret the haptic feedback in real-time and correct their shooting technique without having to interrupt their shooting session.
