The impact of expertise on the processing of 2-D and 3-D images: The case of minimal invasive surgery
A-S Blavier, A-S Nyssen
Although 3-D images lead to better performances than 2-D ones in reaching and grasping tasks, the effect of subject expertise on this difference has never been investigated. In order to answer this question in a natural and meaningful setting, we compared the performance of twelve novices (medical students) with that of twelve laparoscopic (2-D view) surgeons and four robotic surgeons, using a new robotic system that allows 2-D and 3-D view. Our results showed a trivial effect of expertise (surgeons generally performed better than novices). Furthermore, we showed that the effect of 2-D and 3-D view was influenced by expertise level: the performance of novices was strongly influenced by 2-D - 3-D difference (they performed significantly better in 3-D than in 2-D), whereas laparoscopic surgeons accurately compensated for the loss of depth perception in 2-D view and achieved similar performance in 2-D and 3-D. Robotic surgeons, used to manipulating robotic system in 3-D, were also influenced by 2-D - 3-D difference (they achieved the same performance as laparoscopic surgeons in 2-D view and a significantly better performance in 3-D).
