Virtual targeting in three-dimensional space

Methods of measuring human gun shot accuracy include tracing real or virtual shots. Issues in utilizing real shots in shot accuracy experiments involve intermittently halting the study to restore the integrity of the apparatus and reduced safety due to fired projectiles. A videogame is an existing form of a virtual targeting system employing a light gun. However, this device limits users to two dimensions. A tracking system was developed to monitor gun movement and firing in three-dimensional space. Two test protocols examined the reliability of the system. The first tested the repeatability of the system while the second verified the accuracy of the system. For 25 targets, with n=9 for each target, the first test revealed average distances missed for x, y and z of 0.08 inches, 0.05 inches and 0.05 inches respectively. The second test determined a system error rate of 0.1 inches. The system provides the ability to determine shot accuracy and location, given specific targets.
