Metrics are widely employed in virtual environments and provide a yardstick for performance measurement. The current method of defining metrics for medical simulation remains more an art than a science. Many studies have demonstrated that trainees who practice laparoscopic skills in a simulated environment will improve their mastery of those skills when tested in that same environment. Fewer studies have been able to document the learning curve for mastery of tasks in a virtual reality simulator. This study will investigate the learning curve for tasks in a virtual reality laparoscopic simulator.
