Claim:
1. A firearm training system, comprising: a device body simulating a firearm that includes a trigger guard having one or more interior facing surfaces that at least partially define a trigger region; and an electronic module including one or more optical sensors observing the trigger region through an opening formed in an opposing interior facing surface along a ceiling of the trigger region of the device body that opposes the one or more interior facing surfaces of the trigger guard, the electronic module tuned to detect incursion of an object within the trigger region based on a defined wavelength or wavelength range of visible or infrared light captured by the one or more optical sensors; wherein the one or more optical sensors have a field of view that includes at least a portion of the one or more interior facing surfaces of the trigger guard, and the one or more interior facing surfaces of the trigger guard have a light absorbent property that includes textured surfaces formed in the material of the trigger guard that reduces light reflection or increases light absorption within the defined wavelength or wavelength range of visible or infrared light to filter reflected light within the defined wavelength or wavelength range of visible or infrared light to a greater extent than one or more other surfaces of the device body located outside the field of view of the one or more optical sensors.
