SHULE is a surgical training tool that combines haptic simulators with serious games. It aims to improve the development time of surgery simulators. The tool has two components - HLogic controls scenario creation/execution, and HOgre is a game platform that adds haptic interaction. SHULE frameworks surgical training scenarios as "serious games" to motivate practice. It also integrates with other educational systems to publish performance results.
