It also has some limitations mainly caused by inaccurate depth perception, limited field of view and more execution time required. Recently, 3D imaging technology had been applied to laparoscopic surgery. However, it brought some visual fatigue and discomfort during or after surgery. In this study, two tasks, peg transferring (more depth perception needed) and circle tracing (less depth perception needed), were used to be performed with two display conditions (2D and 3D) by students from different universities. The result indicated that performance of peg transferring was better in 3D compared with 2D imaging, as it showed lower movement time and errors with 3D imaging. On the other hand, the performance of circle tracing showed the reverse because participants performed worse in 3D imaging. However, no significant difference on decrease of CFF and mental workload was observed. The result from the subjective questionnaires showed performing tasks with 3D images induced more visual fatigue and discomfort. From the analytical results in present study, it can be concluded that 3D imaging had better performance for tasks that require more depth perceptions, but worse when the tasks require less depth perception. Even if the current developments in 3D technology had interesting promises, it is still premature to say the technology provides perfect image quality which is free of limitations. Therefore, to enhance the performance of laparoscopic surgery, it is worth looking forward to 3D imaging technology that can provide a better image quality with minimum side effects.
