In a firearm simulation system enabling a user to project a laser beam from a laser transmitter assembly secured to a firearm toward a target and including a sensing device, a processor and an actuation detection unit coupled to said laser transmitter assembly and said processor to detect actuation of said firearm, a method of simulating firearm operation comprising the steps of:
- (a) detecting impact locations of said laser beam on said target via said sensing device and producing impact information for transmission to said processor;
- (b) detecting actuation of said firearm via said actuation detection unit and transmitting an actuation signal to said processor in response to said detection;
- and
- (c) determining locations of beam impacts on said target from said impact information to simulate a projectile trajectory and determine impact locations relative to said target, wherein said impact information is processed in response to said actuation signal to reduce false detections.
