Summary
A new serious game reveals that a limited field of view significantly increases task completion time in simulated keyhole surgery. This research provides data to develop tools for improving surgical outcomes.
Area of Science:
- Medical simulation
- Surgical technology
- Human-computer interaction
Background:
- Keyhole surgery presents challenges due to a restricted view of patient anatomy.
- Limited field of view is a major limitation in minimally invasive procedures.
- Effective tools for studying these visual limitations have been lacking.
Purpose of the Study:
- To develop an engaging serious game simulating keyhole surgery challenges.
- To quantitatively assess the impact of a reduced field of view on surgical task performance.
- To inform the development of technologies mitigating visual limitations in surgery.
Main Methods:
- An open-source serious game was developed in JavaScript.
- The game simulates selective cauterization during twin-to-twin transfusion surgery.
- Task performance was analyzed under varying fields of view and vascular complexity.
Main Results:
- 25 participants tested the game, with performance data collected.
- A reduced field of view significantly increased task completion time (P<.001).
- Participants found the game engaging and reported enhanced understanding of visual challenges.
Conclusions:
- The serious game effectively demonstrates the impact of limited fields of view in surgery.
- Quantitative data supports the detrimental effect of restricted vision on performance.
- The open-source game can be used by researchers to study surgical limitations.
