Key Points

  • Weapon simulation system that can provide reliable, low latency shot detection to a variety of commercial and custom augmented reality (AR) or virtual reality (VR) systems or live training
  • Trigger Detection Module (TDM) enables a soldier to interact with head-mounted displays (HMDs) with both real and surrogate weapons
  • Cross-platform, cross-domain solution that can be employed quickly


The University of Central Florida invention describes the Trigger Detection Module (TDM)—a lightweight, low-cost solution that can mount in the M4 pistol grip. The TDM enables a soldier to interact with common augmented reality (AR) or virtual reality (VR) head-mounted displays (HMDs) with both real weapons and commercially available surrogate weapons. Traditional weapons training can include firearms and other weapons training using devices and ammunition for simulated weapon use. The training system can include laser technology that is more than 25 years old, is expensive, and does not accurately simulate weapons fire. Current training infrastructure is heavily reliant on manufacturers of expensive surrogate training weapons made solely for training.

Additional configurations of the TDM connect to the Picatinny Rail System (PRS), enabling use on common weapon systems such as the M9. Using either configuration allows head-mounted displays such as the Microsoft Hololens to receive weapon orientation data and high-quality characterized weapon fire events. The TDM supports a robust open Interface Communication Document that can be tailored to suit various end-user live training applications.
