Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? All reviewed studies agreed that increased degree of image rotation decreased performance, though conclusions about the optimal angle varied. → Vajsbaher Tina 2018
q2 i? Camera rotations between 15° and 90° led to a 10 to 30% increase in error due to decreased directional spatial-motor ability. → Vajsbaher Tina 2018

q2 · i? · review · r3
Review synthesis on ergonomic setup. The review reports monitor displays increased performance when located directly opposite the surgeon at a 180° angle, and that "Reduction in performance was reported with camera rotations of 270° angles" and between 15° to 90° angles.
"All studies agreed that increased degree of image rotation decreased performance, although the conclusion in regards to the optimal degree of angle varied."
Discussion¶
Related Claims¶
- Mental rotation ability shows a specific, significant influence on MIS learning and operative performance
- Visuo-spatial ability impacts operative simulator performance in minimally invasive surgery, mainly in inexperienced novices
- Teaching orientation strategies to novice laparoscopic surgeons significantly increases performance and reduces cognitive burden
- Mental rotation ability moderates the alignment benefit: higher-ability participants benefit more from recording–expected angle alignment — related
- Participants informed in advance about a misaligned task angle performed worse and reported higher video cognitive load than those surprised by the misalignment — related
- Mismatch between recording angle and expected angle increases cognitive load both during video observation and during task execution — related
- Recording angle alone does not affect self-reported cognitive load during video observation or task execution — related
