AB  - Introduction: The da Vinci Skills Simulator (DVSS) is an effective platform for 
      robotic skills training. Novel training methods using expert gaze patterns to 
      guide trainees have demonstrated superiority to traditional instruction. Portable 
      head-mounted eye-trackers (HMET) offer the opportunity for eye tracking 
      technology to enhance surgical robotic simulation training. Objective: To 
      evaluate if training guided by expert gaze patterns can improve trainee 
      performance over standard movement training techniques during robotic simulation. 
      Methods: Medical students were recruited and randomized into gaze training (GT, 
      n = 9) and movement training (MT, n = 8) groups. First, the participants reviewed 
      an instructional video, with the GT group emulating expert gaze patterns and the 
      MT group (n = 8) standard movement-based instruction. Training consisted of 10 
      repetitions of "Suture Sponge 3" on the DVSS while wearing HMET; the first three 
      repetitions were followed by group-appropriate video coaching (gaze vs movement 
      feedback), while the remaining repetitions were without feedback. Finally, two 
      multitasking repetitions with a secondary bell-counting task were completed. 
      Primary outcomes included DVSS scores during training and multitasking. Secondary 
      outcomes included metrics collected from the HMET (gaze patterns and gaze 
      entropy). Results: Total score, efficiency, and penalties improved significantly 
      over the training in both groups; the GT group achieved higher scores on every 
      attempt. Total scores in the GT group were higher than the MT group postvideo 
      review (20.3 +/- 21.8 vs 3.0 +/- 6.2, p = 0.047), after coaching repetitions 
      (61.8 +/- 18.8 vs 30.1 +/- 26.2, p = 0.01), and at the last training attempt 
      (73.0 +/- 16.5 vs 63.1 +/- 17.4, p = 0.247). During multitasking, the GT group 
      maintained higher total scores (75 +/- 10.1 vs 63.3 +/- 15.3, p = 0.01), efficiency 
      (86.3 +/- 7.4 vs 77.4 +/- 11.2, p = 0.009), and superior secondary task performance 
      (error: 6.3% +/- 0.06 vs 10.7% +/- 0.11, p = 0.20). Gaze entropy (cognitive-load 
      indicator) and gaze pattern analysis showed similar trends. Conclusion: 
      Gaze-augmented training leads to more efficient movements through adoption of 
      expert gaze patterns that withstand additional stressors.
