Abstract

A user friendly shooting simulating process and training system are provided to more accurately and reliably detect the impact time and location in which a projectile shot from a shotgun, rifle, pistol or other weapon, hits a moving target. Desirably, the shooting simulating process and training system can also readily display the amount by which the projectile misses the target. The target impact time is based upon the speed and directions of the target and weapon, as well as the internal and external delay time of the projectile. In the preferred form, the training system includes a microprocessor and special projectile sensing equipment, and the targets and projectiles are simulated and viewed on a virtual reality head mounted display.
