Summary
The development of an open-source serious game provides a novel, accessible methodology for quantifying the cognitive and performance-based challenges inherent in keyhole surgery. By simulating the restricted field of view typical of laparoscopic procedures, this research establishes a clear correlation between visual limitations and decreased operational efficiency. The primary thesis posits that serious games serve as effective, engaging proxies for clinical environments, allowing researchers to gather robust quantitative data that can inform the development of computational image mosaicking and other surgical support technologies.
Experimental data derived from 25 participants confirms that a reduced field of view exerts a profound impact on task performance, with completion times increasing by 60% to 100% under restricted conditions. Statistical analysis reveals significant performance degradation, with completion times rising from 9.8 seconds to 16.4 seconds in controlled tests. These findings indicate that visual constraints represent a more substantial barrier to task completion than other common surgical difficulties, such as vessel intertwining. The study utilizes standardized metrics, including the NASA-TLX and System Usability Scale, to validate both the cognitive load experienced by users and the overall usability of the simulation platform.
Published in February 2025, this research highlights the utility of gamified simulations in bridging the gap between nontechnical engagement and clinical training. While the current findings demonstrate the efficacy of the game as a data-gathering tool, future iterations are expected to incorporate more clinically realistic environments and broader user demographics to further validate these results. Ultimately, the study confirms that serious games offer a scalable, cost-effective approach to analyzing the ergonomic and visual demands of minimally invasive surgery, providing a foundation for future advancements in surgical visualization technology.
