Surgical Video Review System

You are invited to participate in a research study evaluating a multimodal annotation platform for surgical video analysis.

What will be collected:

Audio recordings of your verbal commentary during video review
Eye-tracking data (gaze position on screen) via the Gazepoint eye tracker
Your assessment responses (button clicks and scores)
Basic demographic information (experience level, specialty)

Key points:

Participation is voluntary — you may withdraw at any time
No identifying information is stored with your data
Audio recordings will be deleted after transcription is verified
All data is stored on Purdue's secure Fortress server

For questions, contact Dr. Fiona Kolbinger ([email protected]) or Zheyuan Zhang ([email protected]).

I have read and understood the above information and agree to participate

GOALS / GEARS Assessment

Standardized Skill Assessment

Watch full procedure videos and score surgical skill using GOALS (laparoscopic) or GEARS (robotic) criteria while providing verbal commentary on each dimension.

📊 5 Videos⏱️ ~15 min each

Open Review

Open Peer Commentary

Watch full procedure videos and provide open-ended verbal commentary on surgical quality — technical execution, decision-making, safety moments, and specific things to work on.

🎬 5 Videos⏱️ ~15 min each

Dimension	1 (Poor)	3 (Average)	5 (Excellent)
1. Depth Perception	Constantly overshoots	Some overshooting	Accurately directs
2. Bimanual Dexterity	One hand, poor coordination	Both hands, not optimal	Expert complementary use
3. Efficiency	Uncertain, tentative	Slow but planned	Confident, efficient
4. Tissue Handling	Rough, tears tissue	Reasonable, minor trauma	Gentle, negligible injury
5. Autonomy	Unable even with guidance	Needs moderate guidance	Completes independently

Dimension	1 (Poor)	3 (Average)	5 (Excellent)
1. Depth Perception	Constantly exceeds target	Some failures but corrected	Directs in correct plane
2. Bimanual Skill	One hand, poor coordination	Both hands, not optimal	Complementary for exposure
3. Efficiency	Tentative, no progress	Slow but organized	Confident, efficient
4. Force Control	Jerking, tears tissue	Reasonable handling	Proper handling, no breaking
5. Autonomy	Unable to complete	Some guidance needed	Completes alone
6. Robot Control	Poor position, collision	Occasional collision	Optimal, no collision
