US12663234 - System and method for proximity based assignment

Disclosed embodiments provide systems and methods for simulation of firearm discharge and training of armed forces and/or law enforcement personnel. A motion tracking system tracks motion of one or more users. In embodiments, the users wear one or more sensors on their bodies to allow tracking by the motion tracking system. A scenario management system utilizes position, orientation, and motion information provided by the motion tracking system to evaluate user performance during a scenario. A weapon simulator includes sensors that indicate position of the weapon and/or orientation of the weapon. The weapon simulator may further provide trigger activation indications to the scenario management system. In embodiments, the scenario management system generates, plays, reviews, and/or evaluates simulations. The evaluation can include scoring based on reaction times, posture, body position, body orientation, and/or other attributes.

Claim 1

1 . A computer-implemented method executed by a system for conducting a firearm usage simulation, comprising: assigning one or more head mounted displays (HMDs) to one or more users participating in the firearm usage simulation; detecting a position of each HMD; calibrating a plurality of tracked devices corresponding to each user, wherein the tracked devices include one or more wearable sensors and a weapon simulator; determining which tracked devices correspond to which user by detecting the tracked devices that are in closest proximity to the HMD assigned to each user and associating those devices with the respective user; generating an avatar corresponding to each user; determining, by a motion tracker component, an initial position and subsequent motion and posture of a user, wherein the motion tracker component comprises one or more cameras deployed in an area of the simulation, the one or more cameras being configured to track infrared light emitted from the one or more wearable sensors worn by the user; determining, by the motion tracker component, the one or more wearable sensors, and a user-facing camera included within goggles worn by the user, an initial physiological orientation of the user, wherein a subset of the one or more wearable sensors are affixed to the HMD and are affixed to one or more limbs of the user, wherein each user is represented by their corresponding avatar in the simulation, wherein the avatar’s position, posture and motion in the simulation reflects the user’s position, posture and motion; detecting one or more threats to the user including a weapon discharge in the simulation; and determining, by a data analysis component, a reaction of the user in response to the threats and whether the user discharged their weapon simulator. assigning one or more head mounted displays (HMDs) to one or more users participating in the firearm usage simulation; detecting a position of each HMD; calibrating a plurality of tracked devices corresponding to each user, wherein the tracked devices include one or more wearable sensors and a weapon simulator; determining which tracked devices correspond to which user by detecting the tracked devices that are in closest proximity to the HMD assigned to each user and associating those devices with the respective user; generating an avatar corresponding to each user; determining, by a motion tracker component, an initial position and subsequent motion and posture of a user, wherein the motion tracker component comprises one or more cameras deployed in an area of the simulation, the one or more cameras being configured to track infrared light emitted from the one or more wearable sensors worn by the user; determining, by the motion tracker component, the one or more wearable sensors, and a user-facing camera included within goggles worn by the user, an initial physiological orientation of the user, wherein a subset of the one or more wearable sensors are affixed to the HMD and are affixed to one or more limbs of the user, wherein each user is represented by their corresponding avatar in the simulation, wherein the avatar’s position, posture and motion in the simulation reflects the user’s position, posture and motion; detecting one or more threats to the user including a weapon discharge in the simulation; and determining, by a data analysis component, a reaction of the user in response to the threats and whether the user discharged their weapon simulator.
