The disclosed invention contemplates a device and method related to training medical personnel (i.e., for example, surgeons) to perform endoscopic procedures. The disclosed technology solves two problems currently present in the art of using surgical simulators. The first improvement provides a dynamic training program, rather than a program that is the same for every training run. In one embodiment, the device provides a target array that can change position in three dimensions during the training session. In one embodiment, the target array can also change position at various velocities. Consequently, the present invention provides improved discrimination between evaluating innate skill of hand-eye coordination versus surgical skill.
