Human behavioral simulator for cognitive decision-making

Abstract

A simulator is disclosed for training a responder to react in situations that have the potential for the use of force when encountering a main character, such as a person, whom a police officer might encounter during a routine stop and search. The simulator is equipped with natural language recognition and processing such that the main character reacts to voice commands from the trainee. In addition, feedback from the weapon and the weapon aimpoint alters the behavior of the main character. The dynamic scenario architecture is responsive to the language and weapon and interacts with the main character to affect the main character's behavior. The main character is equipped with a behavioral model to vary behavior in a given scenario.

1 . A simulator for training a responder to react in situations that have a potential for use of force when encountering a main character in a scene rendering, the main character having the ability to exhibit a spectrum of behavior, the simulator comprising:
 a. a natural language interface for processing voice input from the responder;   b. a weapon tracking system having a weapon aimpoint input, a trigger-pull input and at least one simulated weapon, the weapon tracking system being for tracking aimpoint and trigger-pull from each simulated weapon;   c. a logic module comprising a component interface;   d. an image generator for the main character and the scene rendering, the image generator being responsive to the logic module;   e. the logic module being further responsive to the natural language interface, and the weapon tracking system;   f. wherein the image generator is responsive to the natural language interface, and the weapon tracking system and the logic module, for the main character and the scene rendering to react to the voice input, the aimpoint and the trigger-pull input; and   g. wherein the natural language interface, the logic module, the computer image generator and the weapon tracking system are for training a responder to react in situations that have the potential for the use of force when encountering a character having the ability to exhibit a spectrum of behavior.   
     
     
         2 . The simulator of  claim 1  further comprising an instructor operator station having an output device wherein the logic module and the image generator are responsive to signals from the instructor operator station. 
     
     
         3 . The simulator of  claim 1  having a natural language speech input which is visible on the instructor operator station output device, and input from the instructor operator station overrides the natural language input. 
     
     
         4 . The simulator of  claim 1  further comprising a digital audio capability wherein the main character includes voice output that reacts to voice input from the responder. 
     
     
         5 . The simulator of  claim 1  wherein the natural language interface comprises:
 a. a speaker independent speech recognition system using domain specific corpora for natural language understanding to provide for the trainee to freely converse with the main character presented by the computer image generator;   b. digitized audio for the main character to verbally converse with the trainee; and   c. wherein the main character and the trainee communicate in a natural language.   
     
     
         6 . The simulator of  claim 5  wherein the weapon tracking system comprises, a plurality of simulated weapons, each weapon simulating a different force level from the other weapons for training the responder to respond with varying levels of force. 
     
     
         7 . The simulator of  claim 1  wherein the image generator includes a dynamic scenario architecture module comprising, a behavioral model for affecting verbal and physical responses of the main character. 
     
     
         8 . The simulator of  claim 7  wherein the behavioral model includes a probabilistic model for predetermined outcomes. 
     
     
         9 . A computer program product embodied on a tangible computer readable storage medium for training a responder equipped with a weapon to react in situations that have the potential for the use of force when encountering a main character, the computer program comprising: recognizing natural language for processing speech input from the responder, processing weapon aimpoint and trigger-pull data from the weapon, processing dynamic scenario architecture responsive to the natural language speech recognition and further responsive to the weapon tracking system, determining the main character behavioral states, associating a behavioral state with the main character, and wherein the main character reacts to speech input from the responder, to the weapon aimpoint and the trigger-pull data from the responder, and to the scene rendering. 
     
     
         10 . A simulator system for training a responder equipped with a weapon means to react in situations having the potential for the use of force when encountering a main character, the computer program comprising:
 a. means for natural language recognition and process of speech input from the responder;   b. means for weapon aimpoint and trigger-pull data processing from the weapon;   c. means for processing dynamic scenario architecture responsive to the means for natural language recognition and process, and further responsive to the means for processing weapon aimpoint and trigger-pull;   d. means for determining character behavioral states, associating a behavioral state with the main character, and   e. wherein the main character reacts to the speech input from the responder, to the means for weapon aimpoint and triggering data from the responder, and to the scene rendering.   
     
     
         11 . The simulator system of  claim 10  comprising a means for after action review.
