The Analysis of Human-Gun Interaction Process Based on the Functional Near-Infrared Spectroscopy

This study explored the applicability of the human-gun interaction process using the functional near-infrared spectroscopy (fNIRS). The method overcomes the drawbacks of the electroencephalogram (EEG) method that are susceptible to interference by firing. Using fNIRS technique, this study explores the human cognitive characteristics during the shooting of rifle. The concentration of oxyhemoglobin was the analytical indicators for the brain function. It is concluded that: (1) It was obviously regular in time domain characteristics. The five stages were distinguished: raising - aiming - firing - reaiming - reholding. (2)In the spatial characteristics, the cognitive brain activity was mainly related to the orbital prefrontal cortex (OPFC) and rostral prefrontal cortex (PFC). (3)Through calculating Laterality Index, the higher the level of the shooter, the higher the activity of the right hemisphere brain. This study can make an important contribution to human-gun interaction mechanism.
