“…Learning curves constructed from average execution time for grasping tissue and the average number of grasp attempts over a given procedure gradually decreased over subsequent surgical experiences, asymptoting between 30-40 procedures before surgical competence was reached under -S-R paradoxical viewing conditions. Gould and Frydman (2007) found for similar improvements general surgery residents using a video trainer under -S-R reverse-alignment paradoxical view conditions, and minor improvements in performance have been reported by placing the monitor at different positions relative to the viewer (e.g., Haveran, et al, 2007), or partially rotating versus inverting the image (e.g., Inagaki, et al, 2021). However, there are no straightforward links to gamification training using modifications to existing games and/or controllers like the previously discussed methods to help novice surgeons to overcome the -R-E fulcrum effect.…”

From video games to laparoscopic surgeries, individual differences in users’ abilities to effectivelyadapt to new control schemes when interacting with 2D displays as proxies for 3D environments canhave significant, even deadly impacts on performance. Starting with the question of why some videogame players invert the y-axis on their console controllers, this work aims to provide a foundation forfuture investigations of how inconsistent control schemes (e.g., an inverted camera view) cansignificantly impact performance. We argue that fragmented research across human factors,ergonomics, cognitive science, and related fields hinders a unified understanding of how the spatialrelationships between users, interfaces, and visual displays affect performance. Therefore, we beginwith a multidisciplinary literature synthesis, clarify existing findings, and identify methodologicalinconsistencies that contribute to conflicting results. We then explore the relationship between y-axisinversion preference and key behavioral and cognitive factors in a group of experienced 3rd persongamers. Based on the results of this preliminary study contextualized within the reviewed literature, wepropose a “general purpose” framework to systematically investigate how control inversion and visualinput influence perception and performance across various movement goals, applicable to both singleand multi-user real-world situations.

“…Furthermore, there is a large difference in the proficiency between experts and nonexperts. [ 10 , 11 ] The puncture of Rob port R1 and Con-Lap port L1 are also performed in the identical conditions, but the reason the results differ significantly from Rob port R4 and Con-Lap port L3 may be because Rob port R1 and Con-Lap port L1 have been performed by advanced surgeons. In addition, on the left side of the patient, the sigmoid colon runs in parallel with the common iliac artery.…”

Objectives: Port placements at the mid-abdomen (mainstay of robotic surgery [Rob]) appear to be difficult compared to that at lower abdomen (mainstay of conventional laparoscopy [Con-Lap]). We hypothesized that the reason for this may be the difference in port puncture places. Materials and Methods: We examined how the differences between the place and puncture order of ports affected Con-Lap cases with ports mainly placed in the lower abdomen and Rob cases with ports mainly placed in the middle abdomen. The trocar time was measured from the time when the puncture position and skin incision were determined and initiated, respectively, to the time when the port was punctured and fixed and used as the indicator of difficulty. Results: In the Con-Lap group analysis, the trocar time of the left lower port was longer (right lower: 77 s, middle lower: 117.5 s, and left lower: 138 s, P < 0.0001). In the Rob group analysis, the trocar time of the left most port was significantly longer (right-most: 89.0 s, right-middle: 92.5 s, left-middle: 121.0 s, and left-most: 197.0 s; P < 0.0001). In addition, the total trocar time was significantly longer in the first puncture at the right-middle port in the Rob group (right-most first: 8.4 min, right-middle first: 12.4 min, and left-middle first: 8.5 min, P = 0.0063). Conclusion: In the mid-abdomen port placement, mainstay of Rob cases, the puncture order, and port site have a significant impact on the difficulty of the procedure. It is preferable to avoid initially puncturing the right-middle port in case of the Rob.

“…12,13 In our previous study on mirror-image, we evaluated the difficulty of surgery by performing the operation on a plane in the center of the space, which was considered the easiest place to operate under the mirror-image condition. 14 However, in actual surgery, it is necessary to operate in the 3-dimensional space of the abdominal cavity, which is wide and deep. Furthermore, in actual surgery, even when operating with mirror-image, the ease of operation often differs depending on the surgical location and the hand performing surgery (left or right).…”

Background: Laparoscopic colon surgery frequently requires performing maneuvers under mirror-images conditions; the complexity differs depending on the surgical site location in the abdominal cavity. However, no previous reports have examined this. Methods: Eleven surgeons participated in this study. Operations were performed on 25 points placed at the bottom and sides of a laparoscopic training box under mirror-image conditions. The mean time-point required to operate at each point and variation between surgeons were evaluated. Results: When the right hand was used, time-points to touch the right side-superficial ends were 0.50 to 0.58 and 0.27 to 0.45 for the other sites. With the left hand, time-points to touch the left side-superficial ends were 0.58 to 0.63 and 0.28 to 0.51 for the other sites, indicating that the most difficult manipulation was at the proximal site of the surgical port. The variation in the difficulty according to the spots increased with a decrease in the surgeon’s experience (right hand, r=−0.248; left hand, r=−0.491). Conclusions: In performing laparoscopic surgery under mirror-image conditions, the technical difficulty varies by location, and operating in locations close to the forceps port is the most difficult.
