METHODS: 42 participants (no surgical experience) were randomized to control group (CG)
or feedback group (FG) and video-recorded while completing 2 rounds (R1 and R2) of
suturing tasks on a daVinci surgical robot. Participants were assessed on needle handling
(NH) and needle driving (ND), and feedback was provided via a visual interface after R1
(Fig). For CG: participants were presented with randomly-selected video clips from R1. For
FG: participants were informed of their AI-based skill assessment and presented with …
