Summary
This study developed a novel colonoscope controller for video games, showing experts performed better than novices. This offers a cheaper, more engaging alternative for endoscopy training.
Area of Science:
- Medical Simulation
- Gastroenterology
- Human-Computer Interaction
Background:
- Procedural simulation is key for endoscopy training.
- Commercial simulators face cost and compliance barriers.
- First-person shooter (FPS) games offer popular engagement.
Purpose of the Study:
- To assess if a novel colonoscope controller for an FPS game mirrors real-life endoscopy skills.
- To compare expert endoscopists and novice residents using the controller.
Main Methods:
- Participants played an FPS game (Portal) with a conventional and a modified endoscope controller.
- Evaluated 12 experts and 12 novices on completion time, button presses, and hand motion.
- Analyzed performance differences between controller types and experience levels.
Main Results:
- Experts significantly outperformed novices in completion time and hand movements with the endoscope controller.
- No significant differences were found in button presses or total path length.
- Performance did not differ when using conventional game controls.
Conclusions:
- The endoscope-controlled video game demonstrates similar performance metrics to real-life endoscopy.
- Expertise in endoscopy correlated with better performance on the novel controller.
- This approach presents a potential low-cost, engaging alternative to current endoscopy simulators.
