Key result
3D viewing on the da Vinci robot lowers mental workload versus 2D viewing.
Why the study?
Mental workload differences between 2d and 3d viewing conditions of the da Vinci Surgical robot during training tasks were not well characterized.
Does the 3D viewing condition of the da Vinci Surgical robot reduce mental workload compared to the 2D condition in medical students?
Does the 3D viewing condition of the da Vinci Surgical robot reduce mental workload compared to the 2D condition in medical students?
Using a 3D viewing condition on the da Vinci Surgical robot reduces mental workload for medical students during training tasks compared to 2D viewing.
3D viewing may ease trainee workload; hypothesis-generating for robotic education and requires validation before practice change.
Fifteen medical students performed a standard training task using the da Vinci Surgical robot's 2d and 3d viewing conditions. Measures of mental workload associated with both viewing conditions were assessed using a secondary interval production task as well as the NASA Task Load Index (NASA-TLX) and the Multiple Resources Questionnaire (MRQ). The Results of the NASA-TLX indicated that the 3d viewing condition results in lower scores of mental workload when compared to the 2d condition. The MRQ data provided diagnostic information regarding which information processing pools were stressed in both the 2d and 3d viewing conditions.

Klein et al. (2009) studied this question. 3d viewing condition vs. 2d viewing condition was evaluated on Mental workload assessed using NASA-TLX, MRQ, and a secondary interval production task. The 3d viewing condition of the da Vinci Surgical robot resulted in lower scores of mental workload on the NASA-TLX compared to the 2d viewing condition.
