Methodologies for the analysis, design and evaluation of laparoscopic surgical simulators
First Edition
The problem addressed in this PhD thesis is how to offer an effective and efficient VR means of training in laparoscopic surgery. And more focused to the design of the simulator, the question is to determine what makes it a useful didactic tool. This b
