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
Cursor tracking data (mouse position on screen)
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 (fkolbing@purdue.edu) or Zheyuan Zhang (zhan4101@purdue.edu).

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

Video Evaluation

Video 1

📋 Video Evaluation

⚠️ You must watch the ENTIRE video. You may adjust playback speed or skip less relevant sections, but please ensure you review the full procedure before completing your evaluation.

🖱️ Mouse Tracking — Important:

While watching the video, keep your mouse cursor over the area of the video you are currently focusing on.
Move your cursor to follow your area of attention — for example, point at the instrument tip, tissue, or anatomical structure you are commenting on.
Your cursor position on the video will be recorded alongside your audio commentary to help us understand your focus of attention.
You do not need to click — simply hover your mouse over the relevant area.

GOALS: Global Assessment of Laparoscopic Skills

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

GEARS: Global Evaluative Assessment of Robotic Skills

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
